Readiness findings
Warnings and fixes from the latest readiness report.
-
Fix the x402 manifest shape
The manifest should be JSON and include a services array with endpoint, method, price, network, and asset metadata. Reference
-
Add listing metadata for Bazaar-style catalogs
Name, description, category, tags, owner URL, and contact fields make services usable in agent marketplaces. Reference
-
Publish facilitator and settlement metadata
Expose facilitator details plus asset, payTo, scheme, timeout, and resource fields so clients can verify and settle payments deterministically. Reference
-
Refresh the x402 manifest timestamp
A stale or missing manifest timestamp makes agents doubt whether prices, networks, and facilitator metadata still describe the live endpoint. Reference

Provider actions
Keep evidence useful, then add clearly labeled reach if needed.
Refresh is recommended: Evidence is older than Ontario's 168-hour strict-payment freshness window. Payment cannot improve the grade or edit provider metadata.
Agent handoff: Validate listing_id lst_7993c3750432 with POST https://ontarioprotocol.com/api/x402/refresh-listing/validate. If validation returns ok and local policy allows 0.10 USDC on Base, call POST https://ontarioprotocol.com/api/x402/refresh-listing with {"listing_id":"lst_7993c3750432"}. Probe the 402 challenge before signing locally; never send wallet keys to Ontario.
Readiness evidence kept fresh automatically after the included window, five Bazaar buyer searches re-run weekly with the history shown above, and an optional webhook alert when the grade changes or the endpoint stops answering. Currently maintained until 2026-10-19.
Agent handoff: POST https://ontarioprotocol.com/api/x402/renew-listing {"listing_id": "lst_7993c3750432"} (validate free first at https://ontarioprotocol.com/api/x402/renew-listing/validate)
Payment buys a fresh observation, not a better score, metadata edit, ranking, traffic, or strict-discovery eligibility.
