A4.2/5.0
Scored across 5 tools
Disambiguation4/5
The two verify tools (verify_agent_receipt vs verify_proof_receipt) are the closest pair, but descriptions explicitly distinguish the issuer-native receipt from the common proof-envelope format. prepare_agent_event vs issue_agent_receipt is also clearly delineated as free validation versus paid issuance.
Naming Consistency5/5
All five tools follow a strict snake_case verb_noun pattern (get_, issue_, prepare_, verify_). The convention is applied uniformly with no deviations.
Tool Count5/5
Five tools cleanly map to a receipt lifecycle: key retrieval, preparation, issuance, and two verification paths. Each earns its place with no redundancy.
Completeness4/5
The surface covers key discovery, pre-flight validation, issuance, and verification of both receipt formats, forming a coherent lifecycle. Minor gaps exist around revocation or listing of issued receipts, but core workflows are covered.
Available Tools
5 toolsget_agent_public_keysGet Agent Public KeysARead-onlyIdempotentInspect
Return public keys of this issuer. The operator must establish trust in this issuer independently.
Inputs: no named parameters. Returns: keys, issuer
issue_agent_receiptIssue Agent ReceiptAIdempotentInspect
Persist a signed execution declaration receipt. Public price: 0.002 USDC via x402 on the advertised network. Preserve event, idempotencyKey and payment authorization on retries. Signed declarations do not independently prove execution.
Inputs: event (required), idempotencyKey (required).
prepare_agent_eventPrepare Agent EventARead-onlyIdempotentInspect
Free validation of a locally built execution declaration before issuance. Hash exact input and output bytes locally; supply identifiers and UTC timestamps with milliseconds. Returns the validated event, commitment and logical chain without creating or purchasing a receipt. Use issue_agent_receipt only if a portable signed declaration is needed.
Inputs: event (required). Returns: chain, event, commitment
verify_agent_receiptVerify Agent ReceiptARead-onlyIdempotentInspect
Free verification of an execution event and its unchanged receipt returned by issue_agent_receipt. Checks signature, scope and event commitment against this issuer. No wallet or new issuance required. Use verify_proof_receipt for the distinct common proof-envelope format. A valid signature does not independently prove execution; compare original bytes locally.
Inputs: event (required), receipt (required). Returns: runId, scope, valid, stepId, +3 more
verify_proof_receiptVerify Proof ReceiptARead-onlyIdempotentInspect
Free verification of a common Datoka proof against an independently obtained caller-supplied public trust registry and explicit issuer/scope/chain. Send only the proof, never raw documents. receiptVerified concerns signature, context and dates; status remains incomplete because the artifact is checked locally. No payment, factual accuracy or parent signatures are verified.
Inputs: proof (required), scope (required), trust (required), issuer (required), +1 more. Returns: code, checks, status, receiptId, +3 more
