Liveness check; returns pong and the server version.

Resolves an ERC-8004 agent by agentId or ownerAddress (exactly one selector), returning identity fields plus best-effort endpoints/capabilities parsed from its registration file.

Fetches and verifies an agent's registration file (via its tokenUri): ipfs:// CIDs are verified, data: URIs are inherently verified, https:// is unverifiable in v1 (no on-chain hash commitment).

Reads an agent's Reputation Registry feedback summary (and optionally the raw feedback entries). Always returns honesty caveats — feedback is self-reported by clients and is a weak signal, especially for low feedback counts.

Reads an agent's Validation Registry entries (validator, best-effort method classification, response, timestamp). An agent with zero validations is a normal, successful result — not an error.

Factual trust report for an ERC-8004 agent: runs identity, registration file, reputation, and validation lookups in parallel with graceful partial failure, and returns the raw sections plus deterministic honesty caveats and a short factual natural-language summary. No numeric scoring. taskContext only shapes the summary text.

Searches for ERC-8004 agents by name/capability/description. MVP stub: no local index backend ships yet, so this always returns INDEX_UNAVAILABLE (input validation still runs first).

Lists the chains this server is configured for. Every other tool's chain argument must be one of the chain slugs returned here; isDefault marks the chain used when a tool call omits chain (DEFAULT_CHAIN_ID env resolution).
