write = sends, deletes, buys or posts

catalogue_statsFree
Size and health of the x402 catalogue as of the latest full scan: resources, hosts, verdict counts, and payable endpoints per network.
drift_statusFree
Verdict changes between the two latest full scans (catalogue wide, or for one host), plus the declared model drift watch.
find_endpointsFree
Search the catalogue by host or URL substring. Returns up to `limit` endpoints with their latest verdict, plus the total match count. Use this first when you do not know the exact resource URL. Optional network filter (for example eip155:8453 or solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) and sort=price for the cheapest first.
host_summaryFree
Summary for a host (no time series): first/last seen, current verdict mix, n_resources, total verdict changes, gone_since if absent from the latest full scan, and a small resources_sample.
payability_verdictFree
Latest payability observation for one exact resource URL (path and query included), with the meaning of the verdict, remediation if it cannot be paid, and the per-network options seen.
reportsFree
Published weekly payability reports (from the signed manifest).
verify_signatureFree
Offline EIP-191 verify of a signed nsgoods response. Strips preview/demo post-sign fields, canonicalises (JCS, trying both ASCII escaping modes), recovers the signer, and checks it against the published manifest signers.
x401_statusFree
Current x401 emitter adoption across the scanned catalogue (from the daily watcher).
