Measured tools (10)

• import_registration

  Import an ERC-8004 Identity Registry record (chain_id + ERC-721 token_id + agentURI + owner). Idempotent: re-import updates in place. Returns the canonical record with its deterministic bridge DID (did:viridis:erc8004:<chain>:<token>).

  Parameters:

  • chain_id (required) — integer
  • token_id (required) — integer
  • agent_uri (required) — string
  • owner (required) — string
  • metadata

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• resolve_agent

  Resolve an imported ERC-8004 registration by bridge DID or by (chain_id, token_id).

  Parameters:

  • chain_id
  • token_id
  • bridge_did — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• import_feedback

  Import ERC-8004 Reputation Registry feedback records for an agent. Each item: {value: bool|0..1, at: ISO-8601, source?, weight?, feedback_id?}. Idempotent per feedback_id.

  Parameters:

  • chain_id (required) — integer
  • token_id (required) — integer
  • feedback (required) — array

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• score_agent

  Decay-weighted trust score in [0,1] + tier over the agent's imported ERC-8004 feedback — recent behavior outweighs old; no feedback scores a neutral 0.5 prior (no blind trust, no unfair zero).

  Parameters:

  • chain_id
  • token_id
  • bridge_did — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• bind_identity

  Bind a fleet DID to an ERC-8004 identity. Produces an order-independent, content-addressed (unsigned) binding attestation.

  Parameters:

  • fleet_did (required) — string
  • chain_id (required) — integer
  • token_id (required) — integer
  • proof_note — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• export_attestation

  Export the agent's current trust score as an UNSIGNED ERC-8004 Validation Registry-shaped payload, content-addressed and ready for YOUR OWN signer to anchor on-chain.

  Parameters:

  • chain_id (required) — integer
  • token_id (required) — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• verify_attestation

  Recompute a payload's content hash and report whether it is intact.

  Parameters:

  • payload (required) — object

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_registrations

  List all imported ERC-8004 registrations.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• export_validation_response

  Build UNSIGNED ERC-8004 Validation Registry validationResponse args from an Outcome Receipt (ORC v0.1): responseHash = receipt commitment, tag "orc/0.1", response 100 only if the bridge re-verifies the receipt AND your replay succeeded. Sign and submit with your own signer; this bridge holds no keys and writes to no chain.

  Parameters:

  • receipt (required) — object
  • request_hash (required) — string
  • response_uri (required) — string
  • replay_ok (required) — boolean

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• describe_agent

  Return the bridge's capabilities and input contract.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
