How this service works
Machine-verifiable official-source evidence with free preflight and x402 USDC payments on Base.
Output
A JSON response containing a 'result' field with one of OBSERVED, NOT_OBSERVED, or INCONCLUSIVE; a schema identifier ('arakel.counterparty-evidence.v1'); and an Ed25519 cryptographic signature attesting to the result's authenticity. The signed proof can be stored or presented as machine-verifiable evidence.
Example use cases
Pre-deal counterparty due diligence
“Before we sign this vendor contract, can you check if 'GlobalTrade Partners Inc' appears in any official records from 2023-01-01 to 2024-12-31 and get me a signed attestation of the result?”
Compliance NOT_OBSERVED proof
“I need a cryptographically signed proof that 'Nexus Capital SRL' was NOT observed in any official sources between 2022-06-01 and 2023-06-01 — get that from ARAKEL so I can attach it to our compliance file.”
Sanctions or registry spot check
“Run a quick machine evidence check on the entity 'Redwood Freight Ltd' for Q3 2024 — I want to know if they show up as OBSERVED in official records and get back a signed result I can log.”
Technical details
Endpoint
HEADhttps://proof.arakelproof.space/v1/machine/counterparty-evidenceWhen to prefer
Choose this endpoint when you need a cryptographically signed, machine-readable attestation (including NOT_OBSERVED proofs) about a named counterparty from official sources — especially for compliance workflows, due diligence audits, or automated agent pipelines that require verifiable evidence rather than a human-readable report. Prefer this over generic web searches or unverified lookups when legal or regulatory defensibility of the evidence matters.
Side effects
- Missing required query parameters (entity, from, to) returns a 400-level error
- Entity string not recognized in enabled official sources returns INCONCLUSIVE
- Date range outside available data coverage returns INCONCLUSIVE or error
- Payment not included or insufficient (x402 protocol) results in 402 Payment Required
- Service unavailability from upstream official sources may delay or block response
