How this service works
Build a standardized, signed run receipt for an agent tool call from a .tine artifact or a raw run record: flat 8-field receipt (mcp_server_id, tool_name, input_hash, output_hash, allowed_scopes, side_effect_class, denial_reason, replay_link) plus a payment/artifact binding block. Ed25519-signed.
Output
A flat 8-field run receipt containing mcp_server_id, tool_name, input_hash, output_hash, allowed_scopes, side_effect_class, denial_reason, and replay_link, plus a payment/artifact binding block, all signed with an Ed25519 signature for cryptographic verifiability.
Example use cases
Audit trail for billed agent actions
“I need a signed run receipt for the tool call my agent just completed — here's the input JSON body and the output it returned — produce the full receipt with input_hash, output_hash, allowed_scopes, and bind it to the USDC payment that was made.”
Compliance log for MCP tool invocations
“My compliance system needs a standardized Ed25519-signed receipt for every MCP tool call — take this raw run record with the POST body and response, and generate the 8-field receipt including the side_effect_class and denial_reason fields.”
Replay-linkable receipt from a .tine artifact
“I have a .tine artifact from a recent agent run and I need to turn it into a verifiable signed receipt with a replay_link so I can reproduce or dispute the result later — can you generate that from the artifact?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/run-receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cryptographically signed, standardized audit receipt for an AI agent tool call — especially when payment accountability, replay verification, or compliance logging is required. Prefer this over ad-hoc logging when you need Ed25519-attested records that can be independently verified or replayed, or when integrating with x402 payment rails that require receipt binding.
Side effects
- Missing required 'input' or 'output' fields returns a validation error
- Malformed body type (not json/form-data/text) causes schema rejection
- Invalid HTTP method (not POST/PUT/PATCH) causes rejection
- Signing failure if internal key material is unavailable
- Payment verification failure if x402 payment header is missing or invalid
