Tool

Description

identity__register_agent

Register (or idempotently update) an agent identity. Returns a deterministic content-addressed DID. capabilities is a non-empty list of lowercase capability tags other agents can discover you by.

identity__resolve_agent

Resolve an identity by agent_id or DID to its full public registration.

identity__discover_agents

Find ACTIVE agents matching ALL requested capabilities (AND semantics), deterministically ordered by match count then reputation.

identity__revoke_agent

Revoke an identity: it disappears from discovery (terminal) but its record is retained for auditability.

identity__list_registrations

List registrations, optionally filtered by status (ACTIVE|REVOKED).

identity__describe_agent

Fleet-standard self-description.

trust__record_outcome

Record an interaction outcome for an agent. kind: success | delivered | dispute_won | failure | undelivered | dispute_lost | timeout | security_incident (security incidents carry a 3x penalty).

trust__score_agent

Get an agent's decay-weighted trust score in [0,1] and tier. Unknown agents get a neutral 0.5 prior — no blind trust, no unfair zero.

trust__attest

Issue a tamper-evident (hash-chained) trust attestation for an agent.

trust__verify_attestation

Verify a previously issued attestation by recomputing its hash.

trust__history

Full outcome history + attestation count + current score for an agent.

trust__describe_agent

Fleet-standard self-description.

escrow__open_escrow

Open an escrow between payer and payee. amount_minor is a positive integer in minor units (cents). The platform fee is computed and FROZEN at open (ceil bps). Returns the escrow_id (state OPEN).

escrow__fund_escrow

Mark an OPEN escrow as FUNDED (idempotent). payment_ref links the payment-rail transaction.

escrow__release_escrow

Release a FUNDED/DISPUTED escrow to the payee (exactly-once — a repeat release returns the existing terminal record, never a double payout).

escrow__refund_escrow

Refund an OPEN/FUNDED/DISPUTED escrow to the payer (exactly-once). Refunding an OPEN escrow is a cancel.

escrow__dispute_escrow

Move a FUNDED escrow to DISPUTED. An arbiter (agent-arbitration-agent) then resolves it to release or refund.

escrow__escrow_status

Current record for an escrow.

escrow__list_escrows

List escrows, optionally filtered by state (OPEN|FUNDED|RELEASED|REFUNDED|DISPUTED).

escrow__verify_audit

Validate the tamper-evident audit hash chain for an escrow.

escrow__describe_agent

Fleet-standard self-description.

metering__create_meter

Create a usage meter between a provider and a consumer agent. unit: what is being counted (call, token, kwh, ...). Price is in minor currency units (cents) per unit. Returns the meter_id.

metering__record_usage

Record a usage event. Idempotent on event_id (safe to retry — never double-billed). outcome is 'ok' or 'error' and feeds the SLA report.

metering__usage_summary

Totals for a meter: event count, total quantity, accrued minor units.

metering__sla_report

Pure SLA report: success_rate vs sla_target, breach flag. No mutation.

metering__describe_agent

Fleet-standard self-description.

arbitration__set_trust_scores

Attach trust-oracle reputation scores (party -> [0,1]) as ruling inputs.

arbitration__rule

Issue the deterministic ruling: allocates 100% of the disputed amount from evidence weights + trust scores, and emits an escrow instruction (release/refund). Exactly-once — re-ruling returns the existing ruling.

arbitration__verify_ruling

Recompute the ruling from its cited evidence + trust inputs and check it matches the stored allocation (machine-checkable justice).

arbitration__get_case

Fetch the full case record, including any ruling.

arbitration__list_cases

covenant__check_act

Check (and if allowed, record) a proposed act against a covenant. Deny-by-default. Idempotent on act_id — retries never double-consume budget. Every check lands on the audit chain.

provenance__get_certificate

Fetch an agent's genesis certificate + recall/quarantine status.

provenance__verify_certificate

Verify a certificate: recompute its content hash and check the ledger.

provenance__lineage

Full ancestry and descendants of an agent, plus its generation number.

offsets__buy_offset

Retire mass_g of verified credits for a buyer: cheapest-first matching, exactly-once (idempotent on purchase_id), returns a content-addressed offset certificate with per-fill costs. Payment settles via escrow. dry_run=true previews the exact fills/cost without mutating the book.

offsets__buy_offset_budget

Money-denominated offset purchase: retire the maximum cheapest-first verified mass whose exact cost fits inside budget_minor (never overspends). Built for callers whose restoration obligation is a currency amount — e.g. a revenue share accrued in a ledger. Idempotent on purchase_id; dry_run=true previews without mutating.

offsets__settlement_batch

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

erc8004__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.

erc8004__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).

erc8004__bind_identity

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

File a claim against an ACTIVE bond. Claims pay out ONLY when an arbitration ruling upholds them (see slash_bond).

surety__slash_bond

Execute an arbitration ruling against a claim. Requires the ruling's case id + content hash from agent-arbitration — no ruling, no slash; a given ruling pays at most once. Payout caps at the bond's available balance (over-claims exhaust the bond).

surety__release_bond

Release the remaining stake to the principal after the coverage window elapses — refused while any claim is still open.

surety__bond_status

Current record for a bond (state, balances, claims, audit head).

taxcredit-engine__calculate_tax_credit

Calculate an auditable tax-credit scenario. credit is 45Q, 45V, 45Y, 48E, or 45X. facts must contain the explicit credit-specific eligibility facts; missing facts return indeterminate. This is not tax or filing advice.
