# Agent Weather x402 Health Report > Agent Weather x402 Health Report is a paid API for AI agents from api.agentweather.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15). Returns a full health report for known XRPL x402 endpoints: liveness, valid-402 status, price/payTo drift, catalog reachability, and t54 facilitator health. ## Facts - Endpoint: GET https://api.agentweather.io/v1/health/report?utm_source=zero.xyz - Price: $0.01/call - Payment: x402 - Status: unknown - Last checked: 2026-10-15 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/agent-weather-x402-health-report-5d703093 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_E3u27nWXMHISVgsCes7Mq Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability agent-weather-x402-health-report-5d703093 ``` Example prompt: Pull the latest x402 health report for all known XRPL endpoints — I want to see which ones are live, which have drifted in price or payTo address, and whether the t54 facilitator is healthy before I start sending payments. ## When to prefer this Use this endpoint when you need a comprehensive, aggregated view of the entire XRPL x402 ecosystem health before initiating payments — covering liveness, drift detection, and facilitator status in a single call. Prefer it over probing individual endpoints yourself when you want pre-validated 402 status, multi-endpoint drift history, and facilitator health together. Not suited for deep per-endpoint payment analytics (use the x402-activity endpoint for that) or for non-XRPL payment rails. ## Known failure modes - Payment required (402) if x402 payment header not provided — endpoint itself is paywalled at $0.01 USDC - Stale data if probed endpoints were unreachable during the last 20-minute cycle - Partial results if some merchant /.well-known/x402 catalogs were unreachable - Facilitator health may show incomplete data if t54 ledger scan had gaps - Response may be truncated if upstream endpoints timed out during the probe cycle ## How this service works Use when you need pre-flight readings of liveness, valid-402 status and price/payTo drift for known XRPL x402 endpoints. Health of known x402 endpoints on XRPL and of the t54 facilitator: per-endpoint liveness and valid-402 check from one unpaid GET every 20 min (merchants' own /.well-known/x402 catalogs plus endpoints we discovered), price, asset, network and payTo drift versus the previous check, catalog reachability, and facilitator health from /supported reachability and our own ledger scan (success rate, fee spikes, tagged volume). JSON with sources and data gaps. Example (illustrative): GET /v1/health/report → {endpoints:[{url, status, valid_402, ms}], drift[], facilitator}. Price: 0.01 RLUSD on XRPL mainnet (xrpl:0; RLUSD issuer rMxCKbEDwqr76QuheSUMdEGf4B9xJ8m5De) or 0.01 USDC on Base. Terms: https://api.agentweather.io/v1/terms ## Output A JSON health report containing: a list of probed x402 endpoints with liveness status, HTTP status code, valid_402 flag, and latency; drift events (price, rail, payTo changes vs previous cycle); merchant catalog reachability; t54 facilitator health (reachability, on-ledger success rate, fee and tagged volume status); metadata including cycle number, timestamps, sources, and data gaps. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "properties": { "type": "string" } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "drift": { "recent": [ { "at": "2026-10-12T02:31:29.381Z", "to": "356", "url": "https://x402.n9t2.com/rpc", "from": "355", "kind": "price", "rail": "xrpl:0|XRP|", "cycle": 516 }, { "at": "2026-10-12T02:31:29.381Z", "url": "https://api.agentweather.io/v1/agent-weather/x402-activity", "kind": "rail_added", "rail": "eip155:8453|0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913|", "cycle": 516, "amount": "10000" } ], "this_cycle": [ { "to": "356", "url": "https://x402.n9t2.com/rpc", "from": "355", "kind": "price", "rail": "xrpl:0|XRP|" }, { "url": "https://api.agentweather.io/v1/agent-weather/x402-activity", "kind": "rail_added", "rail": "eip155:8453|0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913|", "amount": "10000" } ] }, "sources": [ { "url": "https://api.agentweather.io/v1/methodology#health", "name": "Agent Weather health checker: one unpaid GET per known x402 endpoint and merchant /.well-known/x402 per cycle", "observed_at": "2026-10-12T02:31:29.366Z" } ], "data_gaps": [ { "gap": "facilitator settlement latency", "reason": "not observable on-ledger; only our own sales' claim->settle time is shown (small sample)" } ], "endpoints": { "cycle": 516, "probed": 77, "results": [ { "ms": 32, "url": "https://agent-commerce.emergedigital.com/api/xrpl/llms-txt-generate", "http": 402, "rails": [ { "asset": "XRP", "amount": "900000", "pay_to": "rERHPAkbSH8bEHYJWKDERJJ9meDab8Zb1N", "network": "xrpl:0" }, { "asset": "RLUSD", "amount": "1", "pay_to": "rERHPAkbSH8bEHYJWKDERJJ9meDab8Zb1N", "network": "xrpl:0" } ], "status": "live_402", "valid_402": true } ], "catalogs": [], "checked_to": "2026-10-12T02:31:29.366Z", "broken_share": 0.104, "checked_from": "2026-10-12T02:31:03.519Z", "status_counts": { "live_402": 58, "not_found": 6, "invalid_402": 1, "client_error": 1, "server_error": 1, "live_200_no_payment": 1, "live_402_testnet_only": 1, "live_405_get_not_allowed": 8 } }, "issued_at": "2026-10-12T02:34:12.090Z", "report_id": "awh-2026-10-12T0234Z", "facilitator": { "ok": true, "level": "ok", "reasons": [ "t54 reachable; on-ledger success rate, fees an … (truncated) ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/agent-weather-x402-health-report-5d703093/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from api.agentweather.io](https://www.zero.xyz/host/api.agentweather.io/llms.txt)
