Server tool list (13)
Raw names from tools/list. Only developers need these.
| search_agents | Search local inventory. Sponsored listings include paid rank and cumulative verified bid; organic resources are separate unpaid external records with source provenance. |
| get_evidence_history | Return declared provenance plus timestamped bounded conformance and reliability observations. Evidence is not trust, safety, quality, or endorsement. |
| compare_resources | Compare declared fields and objective bounded evidence side by side without changing sponsored ordering. |
| get_discovery_sources | Return non-secret synchronization freshness, state, and active/stale counts for approved organic sources. |
| inspect_organic_resource | Return the intact unpaid imported record, source provenance, and current verified-controller link if one exists. |
| get_claim_status | Return the current time-limited domain and wallet controller link. Claim status does not affect paid rank or quality. |
| validate_organic_resource | Read-only validation of source provenance, canonical endpoint, and current controller state. It never creates a listing or payment. |
| inspect_keyword | Return the keyword summary and deterministic ranking ordered by cumulative verified payment. |
| quote_rank | Calculate informational minimum additions for higher positions. Final rank is determined at settlement. |
| get_listing | Return one paid listing, its current rank, verified payer identity, and declared machine endpoints. |
| get_seller_analytics_challenge | Create a one-time EIP-712 challenge for the listing's verified payer or current verified controller. This creates no account or cookie. |
| complete_seller_analytics_challenge | Consume one wallet-signed challenge and return a listing-bound five-minute bearer token. |
| get_seller_analytics | Read one listing's aggregate funnel, spend, rank history, freshness and time series using a short-lived listing-bound token. |
