x402
Conclave x402 Listing Watch is a paid API for AI agents from conclavex402p04.pythonanywhere.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-16).
Fetches a cached snapshot of one x402 listing from a fixed public directory to detect changes or verify its current state before paying.

How this service works
Pay-per-call x402 data endpoints behind one public payTo: a normalized Solana token snapshot and a multi-rail status snapshot, plus deterministic /u/* micro-utilities.
Output
Returns a JSON object containing the listing ID, payee address, array of resources with their tags, accepted payment assets (network, asset, amount), resource URL, description, and last-updated timestamp, plus a 'changed' boolean indicating whether the snapshot differs from a prior state, a 'fetched_at' timestamp, and a 'snapshot_token' for integrity reference.
Example use cases
Pre-payment listing integrity check
“Before I send any USDC to that x402 endpoint, grab the listing snapshot for ID '0xABC123' in the 'bazaar' directory so I can confirm the payee address and accepted assets haven't changed.”
Automated listing change detection
“Check the x402 listing watch for ID 'svc_99' under the 'payai' directory and tell me if the 'changed' flag is true — I want to know if anything shifted since our last snapshot.”
Auditing a new x402 seller
“I'm about to integrate a third-party x402 service listed under the 'github' directory with ID '0xDEF456' — fetch its current listing snapshot so I can review the resource list and payment requirements before trusting it.”
Technical details
Endpoint
GEThttps://conclavex402p04.pythonanywhere.com/v1/listing-watch/%7Bdirectory%7D/%7Bid%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify or monitor a specific x402 listing by directory and ID before committing to a payment — particularly when you want to detect whether listing metadata (payee, resources, accepted assets) has changed since a prior check. Prefer this over the x402 Integrity Check endpoint when you want a cached directory snapshot rather than a live catalog-vs-live comparison. Best suited for pre-payment due diligence workflows and automated change-detection pipelines operating on known x402 directories.
Side effects
- Invalid or unknown directory/ID combination returns a 404 or error body
- Directory or listing not found in the fixed public catalog returns an error
- PythonAnywhere hosting may introduce occasional cold-start latency or downtime
- Missing required path parameters (directory or id) results in a routing error
- Payment failure (insufficient USDC balance) prevents the call from completing
- Stale cache may not reflect real-time changes if the snapshot TTL hasn't expired
