Hive Sla Monitor

hive-mcp-sla-monitor

SLA observation broker for the A2A network. Agents register a public health endpoint with target uptime and p95 latency; the shim probes it on a 60s schedule (read-only HTTP, 8s timeout) and records the result. When a rolling window misses the targets, a breach record is written. Reading breach records is paid. Inbound only. ENABLE=true by default.

Brand color: #C08D23 (Pantone 1245 C, Hive Civilization gold).

Observation only

Hive does not underwrite or settle SLA claims. This is observational data only. The shim does not hold custody, does not pay claims, and does not indemnify counterparties. The disclaimer rides every paid response and every breach record.

Surface

Layer	Endpoint	Description
MCP	POST /mcp	JSON-RPC 2.0, Streamable-HTTP, protocol 2024-11-05.
Discovery	GET /.well-known/mcp.json	Tool list and transport metadata.
REST	POST /v1/sla/register	Register an endpoint. 402 if no proof.
REST	GET /v1/sla/status/{id}	Read observed uptime and p95. 402 if no proof.
REST	GET /v1/sla/breaches?monitor_id=…	Read recent breach records. 402 if no proof.
REST	GET /v1/sla/today	UTC-day ledger snapshot. Free.
Health	GET /health	Liveness, pricing, recipient address.
Root	GET /	HTML for browsers, JSON for agents (Accept-header sniff).

Tools

Name	Tier	Cost	Description
sla_register	1	$0.01/probe	Register a public endpoint for probing.
sla_status	1	$0.01	Read observed uptime and p95 over the rolling window.
sla_breach_history	2	$0.10	Read recent breach records. Disclaimer rides every record.
sla_unregister	0	free	Deactivate a monitor.

Probe semantics

The scheduler scans active monitors every 60 seconds and issues a GET with an 8-second timeout. 2xx and 3xx count as up; 5xx and timeouts count as down. Probe rows are stored at /tmp/sla.db along with the monitor record and any breach records.

The breach evaluator runs after each probe. It looks at the rolling window (default 60 minutes), computes observed uptime and observed p95 latency, and records a breach if either target is missed. Repeated breaches inside half the window are de-bounced so a single bad window does not fan out.

The service caps active monitors at 100 (SLA_MAX_MONITORS) to keep probe fan-out deterministic.

x402 envelope

Every paid endpoint returns a 402 envelope on first hit:

{
  "error": "payment_required",
  "x402_version": 1,
  "disclaimer": "Hive does not underwrite or settle SLA claims. This is observational data only.",
  "payment": {
    "nonce": "…",
    "amount_usd": 0.01,
    "accept_min_usd": 0.007,
    "accepts": [{
      "chain": "base",
      "asset": "USDC",
      "contract": "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913",
      "decimals": 6,
      "recipient": "0x15184bf50b3d3f52b60434f8942b7d52f2eb436e",
      "scheme": "exact"
    }],
    "tier": 1,
    "product": "sla_register",
    "floor_pct": 0.7
  }
}

Submit the proof inline via X-Payment header on the retry, or POST it to mint an access token used in X-Hive-Access.

Pricing inherits the hivemorph barter floor pattern: the envelope advertises both amount_usd (asking) and accept_min_usd (floor). A client may submit a proof whose on-chain paid amount is anywhere in [floor, asking] and the shim accepts it.

Settlement

USDC on Base L2 (0x833589fcd6edb6e08f4c7c32d4f71b54bda02913) to the recipient address above. Verification reads Transfer logs on the receipt against the configured Base RPC. Real chain reads, no mocks. A single tx_hash may only be redeemed once.

Environment

Variable	Default	Notes
PORT	3000	HTTP port.
ENABLE	true	When false, only /health and / respond.
WALLET_ADDRESS	0x1518…436e	USDC recipient.
SLA_REGISTER_PRICE_USDC	0.01	Per registration.
SLA_BREACH_PRICE_USDC	0.10	Per breach-history read.
SLA_STATUS_PRICE_USDC	0.01	Per status read.
SLA_PROBE_INTERVAL_MS	60000	Probe loop interval.
SLA_PROBE_TIMEOUT_MS	8000	Per-probe HTTP timeout.
SLA_MAX_MONITORS	100	Active monitor cap.
BASE_RPC_URL	https://mainnet.base.org	Base L2 JSON-RPC.
SLA_DB_PATH	/tmp/sla.db	SQLite path.
