Summary
Brings Algorand-based payment rails into Claude through the AlgoVoi platform. You get USDC and native token operations across Algorand, VOI, Hedera, and Stellar chains without leaving your conversation. Reach for this when you're building payment flows or treasury operations that need to touch multiple chains with a unified interface. The stdio transport keeps it local, so you're running payment logic directly from your machine rather than routing through external services. Useful for prototyping cross-chain payment scenarios or automating multi-network treasury management without juggling separate SDKs for each blockchain.

AlgoVoi Platform Adapters
Drop-in payment adapters for connecting e-commerce platforms, AI agent frameworks, and automation tools to AlgoVoi — a compliance-aware crypto payment gateway with native stablecoin support across seven blockchains.
What is AlgoVoi?
AlgoVoi is compliance-aware payment infrastructure for stablecoin settlement. The same gateway that handles payment routing across seven chains also runs continuous sanctions screening, KYB gating, and a write-once SHA-256 audit chain on every payment — so merchants and autonomous agents don't quietly carry UK MLRs / OFAC / SAMLA exposure they didn't sign up for. Compliance posture is published live at /compliance/attestation.
The compliance perimeter is the product. Multi-chain breadth (Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo) and protocol coverage (x402, MPP, AP2, A2A) are how we deliver it on a single endpoint, without merchants having to manage wallets or blockchain integrations directly.
Supported settlement assets:
| Asset | Network | Details |
|---|---|---|
| USDC | Algorand mainnet | Native ASA (ASA ID 31566704), issued by Circle |
| aUSDC | VOI mainnet | Native ASA (ASA ID 302190), Aramid-bridged USDC |
| USDC | Hedera mainnet | HTS token 0.0.456858, issued by Circle |
| USDC | Stellar mainnet | Credit asset issued by Circle (GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN); receiver must have a trust line before accepting |
| USDC | Base mainnet | ERC-20 token (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), issued by Circle |
| USDC | Solana mainnet | SPL token (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v), issued by Circle |
| USDCe | Tempo mainnet | TIP-20 token (0x20c000000000000000000000b9537d11c60e8b50, 6 decimals); Tempo is a Stripe/Paradigm EVM L1 (chain ID 4217) with USDC as the native gas token |
| ALGO / VOI / HBAR / XLM / ETH / SOL | Any mainnet | Native coin payments also supported on every chain (6/6/8/7/18/9 decimals respectively) |
What is this repository?
This repository contains production-ready payment adapters and integration documentation for connecting e-commerce platforms, custom applications, and AI agent services to AlgoVoi Tenant Services.
Included:
- Recurring / standing-authority subscriptions (
Recurr/) — Tier 2 lets a customer sign ONCE and AlgoVoi auto-pulls per cycle on all 7 chains (Algorand SpendingCapVault, EVM ERC-20 approve, Solana SPL Approve, Hedera HTS allowance, Stellar Soroban auth_entry, VOI). Per-chain wallet-side reference flows + chain-agnostic merchant-side examples.native-python/algovoi.pyv1.2.0+ ships the merchant HTTP wrappers (8 lifecycle methods) - Drop-in plugins for WooCommerce, OpenCart, PrestaShop, and Shopware (tested and deployed)
- CMS payment gateways for Drupal Commerce, Easy Digital Downloads (WordPress), and Ghost — all Comet-validated 2026-04-15
- Native adapters for PHP, Python, Go, Rust, and TypeScript (zero external dependencies) — all at v1.2.0 with full Tier 2 (recurring) surface
- Agent protocol middleware for MPP and AP2 (gate APIs behind payment challenges)
- AI platform adapters for OpenAI, Claude, Gemini, Bedrock, Cohere, xAI/Grok, and Mistral (MPP + AP2 + x402, all 7 chains)
- AI agent framework adapters for LangChain, LlamaIndex, CrewAI, Hugging Face, AutoGen, Semantic Kernel, Pydantic AI, DSPy, Vercel AI SDK, Google A2A, LangGraph, and Agno — gate LLM-agnostic pipelines, RAG chains, multi-agent crews, and autonomous agents (MPP + AP2 + x402, all 7 chains)
- No-code / automation adapters for Zapier, Make (Integromat), n8n, and X (Twitter) — drop-in Python classes that bridge AlgoVoi payment flows into any no-code workflow, with webhook verification, MPP + x402 + AP2 challenge generation, and all 14 networks (7 mainnet + 7 testnet); the X adapter auto-posts payment confirmations and checkout links to X via webhook (OAuth 1.0a, stdlib-only, 4-chain mainnet verified 2026-04-18)
- MCP server (
@algovoi/mcp-server/algovoi-mcp) — exposes 13 AlgoVoi tools natively inside Claude Desktop, Claude Code, Cursor, and Windsurf via the Model Context Protocol - x402 embeddable widget for any HTML page (Cloudflare Pages)

CartMandate issues
PaymentMethodDataper extension schema (network,receiver,amount_microunits,asset_id,min_confirmations,memo_required). PaymentMandate acceptspayment_response.details.{network, tx_id, note_field}. ed25519 sig + on-chain AVM verification. PyNaCl + cryptography fallback both confirmed. 81/81 tests.
Two payment flows
Hosted checkout — Customer is redirected to a secure AlgoVoi-hosted payment page. Supports Algorand, VOI, Hedera, Stellar, Base, Solana, and Tempo. Works with any wallet (Pera, Defly, Lute, HashPack, Freighter, LOBSTR, MetaMask, Phantom, …). Payment confirmed via webhook or API status check. Used by all platforms including Shopify.
Extension payment — Customer pays directly on the store page using the AlgoVoi browser extension and algosdk. Supports Algorand and VOI only (AVM chains). Buyers paying on Hedera or Stellar use hosted checkout with their chain-native wallet. No redirect required for extension flow. Available on WooCommerce, OpenCart, PrestaShop, and Shopware.
Shopify checkout extension — "Pay with Crypto →" link rendered on the thank-you page via Shopify Checkout UI Extension (Preact). Customer selects their chain on a dedicated pay page. Webhook automatically adds payment link to order notes.

AI Platform Adapters
Drop-in payment gates for AI provider APIs. Each adapter wraps the AI call behind an on-chain payment check — the caller pays 0.01 USDC (or any configured amount) before the AI responds. All adapters accept OpenAI-format message lists and share a common interface: check(headers, body) → result, complete(messages) → str, flask_guard() convenience method.

AI Agent Framework Adapters
Gate entire orchestration frameworks behind on-chain payment — not just a single model provider. These adapters are LLM-agnostic: pass any pre-built ChatModel, LCEL chain, RAG pipeline, or ReAct agent and the payment check wraps the whole thing.

LangChain — Quick start
from langchain_algovoi import AlgoVoiLangChain
gate = AlgoVoiLangChain(
openai_key = "sk-...", # OpenAI key (or pass llm= to use any ChatModel)
algovoi_key = "algv_...",
tenant_id = "your-tenant-uuid",
payout_address = "YOUR_ALGORAND_ADDRESS",
protocol = "mpp", # "mpp" | "ap2" | "x402"
network = "algorand-mainnet",
amount_microunits = 10000, # 0.01 USDC per call
)
@app.route("/ai/chat", methods=["POST"])
def chat():
body = request.get_json(silent=True) or {}
result = gate.check(dict(request.headers), body)
if result.requires_payment:
return result.as_flask_response()
return jsonify({"content": gate.complete(body["messages"])})
Bring your own model — pass any pre-built LangChain ChatModel instead of an OpenAI key:
from langchain_anthropic import ChatAnthropic
gate = AlgoVoiLangChain(
algovoi_key = "algv_...",
tenant_id = "...",
payout_address = "...",
llm = ChatAnthropic(model="claude-opus-4-7"),
)
Gate any LCEL chain or RAG pipeline:
chain = ChatPromptTemplate.from_template("Answer: {question}") | ChatOpenAI() | StrOutputParser()
result = gate.check(headers, body)
if not result.requires_payment:
output = gate.invoke_chain(chain, {"question": body["question"]})
Drop into a ReAct agent as a BaseTool:
tool = gate.as_tool(resource_fn=lambda q: my_handler(q), tool_name="premium_kb")
from langchain.agents import create_react_agent, AgentExecutor
agent = create_react_agent(llm, tools=[tool], prompt=prompt)
executor = AgentExecutor(agent=agent, tools=[tool])
The tool accepts {"query": "...", "payment_proof": "<base64>"}. Returns a challenge JSON dict if proof is absent or invalid; calls resource_fn(query) and returns the result if verified.
All 7 chains and all 3 protocols supported. Full reference: ai-agent-frameworks/langchain/README.md
LlamaIndex — Quick start
from llamaindex_algovoi import AlgoVoiLlamaIndex
gate = AlgoVoiLlamaIndex(
openai_key = "sk-...",
algovoi_key = "algv_...",
tenant_id = "your-tenant-uuid",
payout_address = "YOUR_ALGORAND_ADDRESS",
protocol = "mpp",
network = "algorand-mainnet",
amount_microunits = 10000,
)
# Gate a LlamaIndex QueryEngine (RAG pipeline)
result = gate.check(headers, body)
if not result.requires_payment:
answer = gate.query_engine_query(query_engine, body["query"])
# Gate a ChatEngine (multi-turn)
if not result.requires_payment:
reply = gate.chat_engine_chat(chat_engine, body["message"])
ReAct agent tool — drop into any LlamaIndex agent:
from llama_index.core.agent import ReActAgent
tool = gate.as_tool(resource_fn=my_handler, tool_name="premium_kb")
agent = ReActAgent.from_tools([tool], llm=llm, verbose=True)
The tool accepts {"query": "...", "payment_proof": "<base64>"}. Returns a ToolOutput with .content (challenge JSON or resource result), .tool_name, .raw_input, .raw_output.
Bring your own LlamaIndex LLM (Anthropic, Google, Cohere, Bedrock, etc.):
from llama_index.llms.anthropic import Anthropic
gate = AlgoVoiLlamaIndex(
algovoi_key = "algv_...",
tenant_id = "...",
payout_address = "...",
llm = Anthropic(model="claude-opus-4-7"),
)
All 7 chains and all 3 protocols supported. Full reference: ai-agent-frameworks/llamaindex/README.md
CrewAI — Quick start
from crewai_algovoi import AlgoVoiCrewAI
from crewai import Agent, Task, Crew, LLM
gate = AlgoVoiCrewAI(
openai_key = "sk-...",
algovoi_key = "algv_...",

payout_address = "YOUR_ALGORAND_ADDRESS",
protocol = "mpp",
network = "algorand-mainnet",
amount_microunits = 10000,
)
# Gate a crew.kickoff() call
result = gate.check(headers, body)
if not result.requires_payment:
output = gate.crew_kickoff(my_crew, inputs={"topic": body["topic"]})
# Or use flask_guard with an inputs extractor
@app.route("/ai/research", methods=["POST"])
def research():
return gate.flask_guard(my_crew, inputs_fn=lambda b: {"topic": b.get("topic", "")})
Add AlgoVoiPaymentTool to any CrewAI agent:
tool = gate.as_tool(resource_fn=my_handler, tool_name="premium_kb")
researcher = Agent(
role = "Research Analyst",
goal = "Use premium_kb to answer questions.",
backstory = "Expert researcher.",
tools = [tool],
llm = LLM(model="openai/gpt-4o"),
)
The tool uses PaymentToolInput (Pydantic args_schema) — the agent generates {"query": "...", "payment_proof": "<base64>"}, CrewAI validates it, and _run(query, payment_proof) is called directly as kwargs. Any crewai.LLM provider (OpenAI, Anthropic, Gemini, Bedrock, Groq, Together AI, …) is supported via the LiteLLM router.
All 7 chains and all 3 protocols supported. Full reference: ai-agent-frameworks/crewai/README.md
Hugging Face — Quick start
from huggingface_algovoi import AlgoVoiHuggingFace
gate = AlgoVoiHuggingFace(
hf_token = "hf_...",
algovoi_key = "algv_...",
tenant_id = "your-tenant-uuid",
payout_address = "YOUR_ALGORAND_ADDRESS",
protocol = "mpp",
network = "algorand-mainnet",
amount_microunits = 10000,
model = "meta-llama/Meta-Llama-3-8B-Instruct",
)
# Gate InferenceClient.chat_completion()
result = gate.check(headers, body)
if not result.requires_payment:
reply = gate.complete(body["messages"])
# Gate a transformers pipeline
from transformers import pipeline
pipe = pipeline("text-generation", model="HuggingFaceH4/zephyr-7b-beta", token="hf_...")
if not result.requires_payment:
answer = gate.inference_pipeline(pipe, body["messages"])
Drop into a smolagents ToolCallingAgent:
from smolagents import ToolCallingAgent, InferenceClientModel
tool = gate.as_tool(resource_fn=my_handler, tool_name="premium_kb")
model = InferenceClientModel(model_id="meta-llama/Meta-Llama-3-8B-Instruct")
agent = ToolCallingAgent(tools=[tool], model=model)
agent.run("Use premium_kb to answer my question.")
The tool accepts query and payment_proof (base64) as kwargs. Returns challenge JSON if proof absent/invalid; calls resource_fn(query) and returns the result if verified. Works with any smolagents agent type (ToolCallingAgent, CodeAgent, custom).

Semantic Kernel — Quick start
from semantic_kernel_algovoi import AlgoVoiSemanticKernel
