How this service works

Agents pay for work and prove what happened.

Output

Returns a JSON object containing: the tool name ('correct_copy'), an ordered action chain showing each step (request, authorization, action, proof, liability_boundary), a status ('complete'), the agent account address, a verdict ('clean' or otherwise), a unique receipt ID, and a receipt version string (embassy-receipt/1) — constituting cryptographically traceable proof of the correction event.

Example use cases

Marketing copy compliance audit

“Run our new product launch copy through Agent Embassy's correction check, pay for it, and save the embassy receipt — I need to show auditors that the copy was independently verified before we published.”

Agent fleet accountability logging

“Have the agent submit this blog draft to Agent Embassy for a copy correctness check, pay the fee, and store the receipt ID and verdict so we have a verifiable chain of what the agent did and who is liable.”

Regulated content sign-off

“Before we send this financial disclaimer copy live, use Agent Embassy to get it corrected and generate a signed receipt proving the review happened, the verdict was clean, and the liability boundary is recorded.”

When to prefer

Choose this endpoint when your agent needs both a content correction result AND a verifiable, on-chain proof-of-work receipt — especially in regulated, auditable, or multi-party workflows where accountability and liability boundaries matter. It is the right choice over a plain proofreading API when you need cryptographic evidence of who authorized the action, what happened, and who bears liability. Prefer it when your pipeline uses x402 micropayments and you want a single call that combines payment, correction, and receipt issuance.

Side effects

Payment authorization fails — returns 402 if USDC funds are insufficient or payment header is malformed
Invalid or missing copy input — returns 400 with validation error
Account address not recognized — receipt may not be linkable to caller
Service unavailable — 5xx if the embassy backend is down
Verdict not clean — copy is flagged, receipt still issued but verdict reflects failure

Input

Schema · Request body

Field	Type	Description
draft	string	The raw draft copy to correct (1-20000 chars)
links	array	HTTPS URLs the copy references; each is verified alive via HEAD (fallback GET), 8s timeout, redirects never followed (max 20)
register	string	Voice register: founder-notes, elite, force, or bright
required_terms	array	Terms that must appear in the final copy (max 20; each term max 100 chars; counted case-insensitively)
idempotency_key	string	Idempotency key: UUID v4, client-generated, one per logical request. Replaying the same key on this tool returns the original receipt — the action is not re-run, and the first request's receipt wins even if you resend different inputs. Published example keys are rejected. Keys are scoped per tool and per payer account: a key never returns another wallet's receipt.
