Nsgoods Workbench tools (8)

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. Identifies the service from the manifest (or the optional `service` arg), strips exactly that service's post-sign fields, canonicalises (JCS, both ASCII modes), recovers the signer and checks it against the published manifest signers. Reproduction-attestation (JCS/byte-length) and envelope (signer/signature, components) shapes are reported as unsupported_shape, not verified here.

  • x401_statusFree

    Current x401 emitter adoption across the scanned catalogue (from the daily watcher).
