Valuein — SEC EDGAR fundamentals for analysts, quants, and AI agents

Point-in-time, survivorship-free SEC fundamentals — built for AI agents, safe enough for institutions that fear AI. Every number is born in a filing and carries a fact_id; the model never mints a digit. Streamed as Parquet, queried with DuckDB or natural language, reproducible run to run.

This repository is the public home and discovery hub for the Valuein data platform. It hosts the documentation, examples, notebooks, and the MCP registry manifest used by AI agents to find us. Source code for the SDK, MCP server, and data pipeline lives in dedicated repositories — this is the front door.

pip install valuein-sdk          # data for code
# or add this URL to any MCP-capable AI client:
# https://mcp.valuein.biz/mcp     # data for agents

The data product

Survivorship-bias-free, point-in-time US fundamentals sourced directly from SEC EDGAR.

• 12M+ filings — 10-K, 10-Q, 8-K, 20-F, 40-F, and amendments since 1993
• 111M+ standardized facts across 19,000+ US public companies — including every bankruptcy, merger, and delisting since 1993
• 11,966 raw XBRL tags normalized to 292 canonical standard_concept values plus 164 materialized financial ratios (FY + TTM); unmapped tags are exposed under 'Other' rather than dropped
• 20 Parquet tables — 14 core (fundamentals, ratios, valuations, index membership, daily OHLCV price history with adjusted close) + 6 smart-money tables (Institutional tier)
• Cloud Parquet on Cloudflare R2 — stream with DuckDB; no database setup, no local downloads
• PIT-correct — every fact carries filing_date and millisecond-precision accepted_at

Why it's different

Property	What it means for you
🕒 Point-in-time	filing_date <= trade_date removes look-ahead bias. accepted_at gives intraday resolution for same-day signals.
⚖️ Survivorship-bias free	Delisted, bankrupt, and acquired companies remain in every snapshot — your backtest sees the universe the market saw.
📊 Standardized concepts	Both the raw XBRL tag (fact.concept) and the canonical name (fact.standard_concept) are on every row. No hidden mapping table.
🔍 CPA-verified catalog	Every standard_concept carries a review_confidence — 1.0 once an accountant has signed off on its name, statement and rule (then it's locked; the pipeline only ever adds new concepts, never mutates a verified one), 0.7 while provisional. Filter review_confidence >= 1.0 for the labels analysts, quants and AI models can agree on and train against.
🚀 DuckDB-native	Millisecond analytics over remote Parquet via httpfs. Zero database provisioning.
🔁 Append-only restatements	A 10-K/A adds a new row — the original stays. Reconstruct the as-reported view of any historical date.
🧾 Measured, published accuracy	Mathematical consistency checked against published, cited accounting identities — CI-gated, and re-derivable yourself with one DuckDB command. The current measured figure lives in docs/accuracy/baseline.json.
🔐 One token, every channel	The same Bearer token authenticates the SDK, MCP server, and bulk-data API.

Built for AI agents

Valuein is MCP-first and agent-agnostic: the same typed tool surface works in Claude, Copilot, ChatGPT, Perplexity, Gemini, Grok, Cursor, or your own LangGraph / CrewAI agent. The design goal is simple — the model never mints a number. Numbers are born in tools, carried as provenance-tagged facts, and the model is only allowed to arrange words around figures it was handed.

Guarantee	How it's enforced
Fact-level lineage	Every figure a tool returns carries a fact_id and its source filing; verify_fact_lineage round-trips any fact_id back to the exact SEC filing URL in one call.
Zero look-ahead	Every time-series tool accepts as_of_date and reconstructs the information set as of that date — the same PIT discipline the Parquet layer enforces for backtests.
Reproducible runs	Deterministic, idempotent tools: same inputs, same output. No rolling windows, no hidden "latest". Agents can cache, retry, and replay; you can reproduce a run later.
Agent-agnostic state	Theses, claims, watchlists, alerts, and reports persist server-side across sessions and across clients — save a thesis from Claude today, list it from Cursor tomorrow.
Human-on-the-loop (HOTL)	Mutating and outward-facing tool actions go through a staged-action approval ledger: the agent proposes, a human approves, and the decision lands in an immutable audit entry. Read-only tools never stage.
Governed managed runs	Server-side managed agent runs execute at temperature 0 with a model allow-list and destructive-tool stripping — reproducible research, not improvisation.
Graded track records	Saved theses and claims are scored against subsequent fundamentals and prices; publishing builds a public, verifiable track record — your agent keeps score.

The full tool reference is in docs/MCP_TOOLS.md; agent-facing runtime instructions are in AGENTS.md.

Plans & access

Pricing and feature scope are mirrored from valuein.biz/pricing — the website is the source of truth and our checkout flow routes to the correct Stripe product.

Plan	Universe	History	Data freshness	Price	Get it
Sample	S&P 500 (~500 tickers)	5-year window	Quarterly snapshots	Free · no signup	Just pip install valuein-sdk
Free	S&P 500 (~500 tickers)	1993 – present	Daily	Free · register	Register
Pro	Full active + delisted US universe (19,000+ entities) — fundamentals dataset only	15-year rolling (2011 → present)	24h after SEC	$49 / mo · $490 / yr	Subscribe
Institutional	Same universe + smart-money dataset (insider transactions on Forms 3/4/5/144 + institutional ownership on Forms 13F/13D/13G)	1993 – present (unlimited)	4h priority + filing-event webhooks	$499 / mo · $4,790 / yr	Subscribe
Enterprise	Negotiated · dedicated infrastructure · expanded redistribution scope	Custom	Real-time 8-K + zero-retention option	Talk to us	sales@valuein.biz

Each tier removes a different buyer objection — Pro removes the universe + history limits on the fundamentals dataset; Institutional adds the smart-money dataset (insider transactions + institutional ownership), unlimited history back to 1993, filing-event webhooks, and a commercial redistribution license under a business-hours SLA; Enterprise adds dedicated infrastructure and bespoke contracts.

Pay-per-call (MPP)

Autonomous AI agents that hit a rate or tier limit can pay per request using Stripe card tokens — no human checkout loop. Payment uses the Machine Payment Protocol. The agent quotes a price, charges a card Shared Payment Token, then retries the MCP call with the confirmed token.

Payment is card-only today. Fetch https://api.valuein.biz/api/mpp/well-known to see which networks are live before paying.

Category	Examples	Price
Provenance / schema	describe_schema, verify_fact_lineage	Free
Discovery	search_companies, get_sec_filing_links	$0.01 / entity
Fundamentals	get_company_fundamentals, get_financial_ratios	$0.10 / entity
Analytics	get_valuation_metrics, get_peer_comparables, compare_periods, get_capital_allocation_profile	$0.50 / entity
Compute	compute_dcf, forensic_audit, generate_dcf_xlsx, generate_research_brief_docx, generate_comps_xlsx	$2.50 / call
Screens / universe	screen_universe, get_pit_universe	$5.00 / call
Smart money (Institutional dataset)	get_insider_transactions, get_insider_sentiment, get_institutional_holdings, get_manager_portfolio, get_blockholders, get_top_holders, get_smart_money_flow	$5.00 / entity

PAYG is priced at 5× the subscription-equivalent rate — steady-state agent usage is almost always cheaper with a Pro or Institutional subscription. Daily spend caps exist per token as abuse protection; caps are raisable on request. See AGENTS.md for the full three-step MPP flow.

The whole pattern — an agent that buys its own data, safely — is written up as a reference implementation in docs/AGENT_ECONOMY_RAIL.md: the two live consent models (a human-authorized bounded budget that auto-charges and serves inline; or per-call MPP for wallet-holding agents), why it's the safe default, and a runnable demo — examples/python/agent_buys_its_own_data.py — that discovers the rail and reads back a live quote for free.

Rate limits per tier (canonical at https://data.valuein.biz/v1/plans):

Plan	Per minute	Per hour
Sample (anonymous)	60	600
Free	60	1,000
Pro	100	3,000
Institutional / Enterprise	300	10,000

Quickstart (30 seconds, no token)

Pick whichever Python workflow you already use — both work in any virtual environment, and both run the same code below:

# Option A — pip (universal, ships with Python)
python -m venv .venv && source .venv/bin/activate
pip install valuein-sdk

# Option B — uv (10–100× faster; install from https://docs.astral.sh/uv/)
uv venv && source .venv/bin/activate
uv pip install valuein-sdk

Zero-friction by design. No VALUEIN_API_KEY? No problem. The SDK detects the missing token and falls back to the SAMPLE dataset (S&P 500, last 5 years); the edge gateway does the same — GET /v1/{sp500,pro,full}/:table with no Authorization header automatically 302-redirects to /v1/sample/:table. The snippet below runs as-is.

from valuein_sdk import ValueinClient

with ValueinClient() as client:
    print(client.me())               # {plan, status, email, createdAt}
    print(client.manifest())         # snapshot id, last_updated, tables
    print(client.tables())           # currently loaded tables

    df = client.run_query("""
        SELECT r.symbol, r.name, r.sector
        FROM   "references" r
        JOIN   index_membership im ON im.cik = r.cik
        WHERE  im.index_name = 'SP500'
          AND  im.removal_date IS NULL
          AND  r.is_active = TRUE
        ORDER  BY r.name
        LIMIT  10
    """)
    print(df)

That's a real query against the live S&P 500 sample. Add a token only when you need full universe or full history:

# optional — sample tier works without a key
echo 'VALUEIN_API_KEY="your_token_here"' >> .env

The same code now reads from your tier — no other changes.

Production pattern — context manager, typed errors, pre-built templates

from valuein_sdk import (
    ValueinClient,
    ValueinAuthError,
    ValueinPlanError,
    ValueinRateLimitError,
    ValueinAPIError,
    ValueinError,
)

# Two-level try/except is intentional:
#   outer = init errors raised by ValueinClient.__enter__ (auth, manifest, 503)
#   inner = per-query errors raised by run_query / run_template (rate-limit,
#           plan denial, bad SQL). Each level dispatches by exception type so
#           you can act on the right cause — exit on auth, sleep on rate-limit,
#           upsell on plan, log + skip on a single bad row.

try:
    with ValueinClient() as client:
        try:
            # 1) Build & run a raw SQL query → pandas DataFrame
            sql = "SELECT COUNT(cik) FROM entity"
            result = client.run_query(sql)
            print(result)

            # 2) Run a named SQL template with kwargs (the SDK quotes safely)
            df = client.run_template(
                "fundamentals_by_ticker",
                ticker="AAPL",
                start_date="2020-01-01",
                end_date="2024-12-31",
                form_types=["10-K", "10-Q"],
                metrics=["TotalRevenue", "NetIncome", "OperatingCashFlow"],
            )
            print(df.head())
        except ValueinPlanError:
            print("This query needs a higher plan — see valuein.biz/pricing.")
        except ValueinRateLimitError as e:
            print(f"Rate limited; retry in {e.retry_after}s.")
        except ValueinError as ve:
            # Catch-all for any other per-query failure (validation, bad SQL, etc.)
            print(f"Query failed: {ve}")
except ValueinAuthError:
    raise SystemExit("Token missing or expired — set VALUEIN_API_KEY.")
except ValueinAPIError as e:
    print(f"Gateway error during init (HTTP {e.status_code}).")
except Exception as e:
    print(f"Initialization failed: {e}")

The SDK ships 60 named SQL templates for the most common screens, ratios, and PIT backtests. List them:

from valuein_sdk import ValueinClient
with ValueinClient() as c:
    print(c.list_templates())

Data model

Full schema in docs/schema.json (machine-readable) and docs/data_catalog.md (canonical concept names). The snapshot ships 20 Parquet tables — the core tables below plus 6 smart-money tables on the Institutional tier (insider_party / insider_filing / insider_transaction / institutional_filing / institutional_holding / insider_ownership).

Table	What it is	Why it matters
references	Start here. Flat join of entity + security. One row per security with cik, is_active, sector, exchange, FIGI. For membership, JOIN index_membership on cik = cik.	One scan for cross-company metadata; index membership stays in its own table so historical entry/exit is preserved.
entity	Company metadata — CIK, name, sector, SIC, status, fiscal year end	The legal entity dimension.
security	Ticker history (SCD Type 2 with valid_from / valid_to)	Resolve historical tickers, share classes, exchanges.
filing	Filing metadata — accession_id, filing_date, report_date, form type, amendment flag	The "what was filed when" dimension.
fact	Standardized financial facts — both raw concept and canonical standard_concept on every row	The numbers. PIT-safe via accepted_at.
ratio	Pipeline-computed financial ratios per filing	Skip the SQL — margins, returns, leverage, efficiency pre-calculated.
valuation	Two-stage DCF + DDM intrinsic values per entity per period	Cross-check your model against ours.
taxonomy_guide	2026 US GAAP Taxonomy	Definitions for every standard_concept.
index_membership	Historical index constituents (SP500, RUSSELL1000, RUSSELL2000, RUSSELL3000) — keyed on cik, with effective_date / removal_date half-open windows	Reconstruct any index on any historical date. JOIN references.cik = index_membership.cik for company metadata.
standard_concept	The canonical concept catalog itself — names, statements, mapping rules, CPA review status	The ground truth behind fact.standard_concept.
stock_price	Latest end-of-day close per entity	Quick current-price joins on any tier.
stock_price_daily	Full daily OHLCV bar series per entity, with adjusted_close and corporate-action factors	Backtest-safe price legs — pair with fundamentals for PIT valuation multiples.

Date columns — which to use when

Column	Table	Use for
report_date / period_end	filing / fact	Aligning to the fiscal calendar
filing_date	filing	PIT backtest filter — when the SEC received it
accepted_at	fact, filing, ratio (+ smart-money and price tables)	Millisecond-precision PIT for intraday research

For any cross-company backtest, always filter by filing_date <= trade_date. Filtering by report_date introduces look-ahead bias.

Three patterns that pay off in DuckDB

1. Start from references (one join for cross-company filters; membership is in index_membership):

SELECT r.symbol, r.name, r.sector
FROM   "references" r
JOIN   index_membership im ON im.cik = r.cik
WHERE  im.index_name = 'SP500'
  AND  im.removal_date IS NULL          -- current member
  AND  r.is_active     = TRUE
  AND  r.sector ILIKE '%technology%'

2. LATERAL for the latest filing per company:

JOIN LATERAL (
    SELECT accession_id, filing_date FROM filing
    WHERE  entity_id = r.cik AND form_type = '10-K'
    ORDER  BY filing_date DESC LIMIT 1
) f ON TRUE

3. Pivot multiple concepts in one fact scan:

SELECT
    MAX(CASE WHEN standard_concept = 'TotalRevenue'       THEN numeric_value END) AS revenue,
    MAX(CASE WHEN standard_concept = 'StockholdersEquity' THEN numeric_value END) AS equity
FROM   fact
WHERE  standard_concept IN ('TotalRevenue', 'StockholdersEquity')
GROUP  BY accession_id

Quarterly cash flows: use COALESCE(derived_quarterly_value, numeric_value) — Q2/Q3 10-Qs report YTD; this column isolates the single quarter. CAPEX sign varies by filer — always ABS(capex).

The full cookbook — 20 recipes, 8 anti-patterns, end-to-end factor screen — lives in docs/QUERY_COOKBOOK.md.

Canonical concept names

Query fact.standard_concept with canonical names like 'TotalRevenue', 'NetIncome', 'OperatingCashFlow', 'CAPEX', 'StockholdersEquity' — not raw XBRL tags ('Revenues', 'NetIncomeLoss', 'Assets'). The full list lives in docs/data_catalog.md and the machine-readable form is in docs/data_catalog.json.

MCP for AI agents

Valuein ships a remote, protocol-native Model Context Protocol server so any MCP-capable agent (Claude, Copilot, ChatGPT, Cursor, custom) can answer fundamentals questions — and keep persistent, auditable research state — without writing code.

• Endpoint: https://mcp.valuein.biz/mcp (Streamable HTTP, MCP spec 2025-11-25)
• Auth: Authorization: Bearer <your_api_token> — same token as the SDK and bulk-data API
• Manifest: server.json — published to registry.modelcontextprotocol.io as io.github.valuein/mcp-sec-edgar
• Reference: docs/MCP_TOOLS.md — every tool, every parameter, every tier gate

Tools

The server exposes 102 live tools, plus 29 agentic SOP prompts (two flagship cross-persona briefs — equity_research_brief and screen_and_shortlist — plus specialised chains for analyst, PM, quant, ratio, smart-money, and workflow personas) and 3 data resources (schema://{table}, reference://sp500, pricing://current). Tier gating happens at the data layer — Sample / Free tokens see Sample / S&P 500 data; Pro sees the full 19,000+-entity universe with a 15-year point-in-time window (2011 → present); Institutional unlocks the smart-money tools (insider transactions on Forms 3 / 4 / 5 / 144 + institutional ownership on Forms 13F / 13D / 13G), unlimited history back to 1993, filing-event webhooks, and the commercial redistribution license.

Public publishing — free reputation building (all tiers)

Publish your saved research to a public @handle profile — free to build a public track record and reputation. Reports become a shareable /r/[slug] page discoverable via keyword catalog search (no semantic search yet); theses and claims get the same free publish / unpublish visibility toggle. This is publishing, not selling; the paid report-marketplace tools (purchase_report, list_my_purchases, connect_stripe_account) remain unreleased.

Tool	What it does
publish_report	Publish a saved report to your public profile (@handle) as a shareable /r/[slug] page
unpublish_report	Take a previously published report private again
search_reports	Search the public report catalog by ticker, author, or keyword (keyword catalog search)
publish_thesis / unpublish_thesis	Toggle a saved thesis public / private on your profile — parity with publish_report
publish_claim / unpublish_claim	Toggle a saved claim public / private on your profile — parity with publish_report

Configure in Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
