Audit Agent Service Discoverability

agent_discoverability_audit

Measure one service's brand-blind rank, source-family coverage, expected-route presence, canonical-vs-alias listing identity, duplicate records, competitors, and exact-price drift across ten public machine-service discovery views. Supply runtimeUrl with an exact GET route to derive the comparison price from one coherent live unsigned x402 or MPP offer; otherwise expectedPriceUsd remains caller-supplied. Set surfaceAudit to check the target's public Agent Card, ERC-8004 registration document, and action catalog. Set materializationAudit with an exact GET or POST route to distinguish Coinbase seller ineligibility from provider acceptance without exact-resource Bazaar materialization. Catalog queries use no credentials or payments. Results are point-in-time provider and catalog evidence, not demand, seller trust, settlement, or future-rank proof. Payment challenge and credentials are bound to GET https://agents.samedaydesk.com/distribution/agent-discoverability-audit, not mcp://. Retry the identical authorized arguments and credential.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
payToNoOptional EVM payTo for alias matching
routeNoOptional expected exact path
intentYesBrand-blind capability description
methodNoExact route method for the optional Coinbase materialization audit. Defaults to GET; runtimeUrl is GET-only.
originYesPublic HTTPS service origin
runtimeUrlNoOptional exact same-origin HTTPS GET URL whose unpaid x402 or MPP offer supplies the runtime price reference. Requires route and an exactly matching pathname.
surfaceAuditNoWhen true, inspect the target's public Agent Card, ERC-8004 registration document, and action catalog for the expected route through bounded same-origin fetches.
expectedPriceUsdNoOptional exact route price expected by the caller. A coherent runtimeUrl offer takes precedence and caller drift is reported.
materializationAuditNoWhen true with route and method, distinguish Coinbase seller ineligibility from provider acceptance without exact-resource Bazaar materialization.
