How this service works

Agents pay for work and prove what happened.

Output

Returns a JSON object containing the tool name ('research_paper'), byte size of the paper, a provenance chain array (request, authorization, action, proof, liability_boundary), a bundle description ('paper+provenance'), completion status, the agent's on-chain account address, a paper_id, a receipt_id, and a receipt_version string — giving full auditability of the transaction.

Example use cases

Auditable agent research retrieval

“Retrieve the research paper 'the-discontinuity-20260922' through Agent Embassy — I need the full paper plus the provenance chain and a receipt so there's a verifiable record that my agent accessed it.”

On-chain proof of content delivery

“My agent needs to fetch a specific research paper and produce a cryptographic proof that it was delivered — use Agent Embassy to get the paper bundle with the liability boundary and receipt included.”

Automated research pipeline with payment

“As part of my research pipeline, have my agent pay for and retrieve the paper 'the-discontinuity-20260922' via Agent Embassy and store the embassy receipt and provenance chain alongside the paper content.”

When to prefer

Choose this endpoint when your agent needs not just a research paper but a cryptographic, on-chain-verifiable proof of what happened — including authorization, delivery, and liability boundaries. It is especially suited for agentic workflows where accountability, auditability, or regulatory traceability of content retrieval matters, and where payment via USDC on-chain is acceptable or required.

Side effects

Insufficient USDC balance causes payment failure and no content is returned
Invalid or unknown paper_id returns an error with no bundle
On-chain authorization failure halts the action step mid-chain
Receipt generation failure may leave payment settled but proof incomplete
Network or RPC issues may cause the payment to process without a response

Input

Schema · Request body

Field	Type	Description
bundle	string	Delivery tier: 'paper' ($222) or 'paper+provenance' ($444, paper plus the corpus proof pack). Defaults to 'paper'.
paper_id	string	Catalog ID of the paper, e.g. 'the-discontinuity-20260922'. Unknown IDs are rejected
buyer_alias	string	Optional license display name (3-32 chars: letters, digits, . _ -). Defaults to the first 8 hex chars of the buyer wallet.
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.
prior_receipt_id	string	Optional receipt-carried tier: a prior research_paper receipt id (emb_...) for the $222 paper tier, owned by the paying wallet. When valid, buying paper+provenance costs the $222 upgrade delta instead of $444. The prior receipt's signature is verified and must belong to the payer; invalid ids are rejected with 400 before settlement. Quoted provisionally at 402 time; ownership proven at run time.
