Tools

• attest_control_baseline ~427 tokens
  File your operator's control-baseline attestation — the counterpart to counterparty_control_baseline. That tool asks what controls the OTHER side runs; this one publishes what YOUR side runs, so payers can see it before settling with you. No account, no key, one call. Gaps are allowed and expected:
• baseline_controls ~118 tokens
  Fetch the OceanAlt Agent Control Baseline: the list of controls an agent operator is expected to run before it is allowed to move money, each answerable yes or no. Call this before attest_control_baseline so you file against real control ids. Each control carries which gate enforces it and why it ex
• check_calldata_intent ~548 tokens
  Anti blind-signing. EVM: decodes what a transaction's calldata will actually do (ERC-20 transfer/approve/permit, setApprovalForAll, ownership transfer, native transfer). Solana: decodes a whole base64 transaction (SPL Token / Token-2022 Transfer, TransferChecked, Approve, SetAuthority, CloseAccount,
• check_payment_request ~582 tokens
  Call this before paying because an email, invoice or chat message asked you to. Pass what you received: raw headers if you have them, the From line, subject and body (or body_html), and the payee address if you already extracted one. OceanAlt checks whether the sender is who it claims to be (SPF/DKI
• counterparty_control_baseline ~238 tokens
  Answers a different question from address screening. Screening asks whether an address is risky; this asks how much damage the agent on the other side could do if it were talked into something. Returns that party's self-attestation against the OceanAlt Agent Control Baseline, split into two sets tha
• evidence_bundle ~171 tokens
  Everything OceanAlt holds about an address as public facts, in one Ed25519-signed bundle you can verify offline: screening verdict with evidence and freshness, profile signals, one-hop relations to listed addresses, fulfillment receipt stats and coverage. A witness, not a prosecutor: no conclusions
• payee_decide ~257 tokens
  The receiving side's check before settlement. Given the payee's registry id (sid) and, optionally, the payer, amount and purpose, returns accept / decline / hold_request_info / not_ready with reason codes, the fields to request, evidence and a signature. Rule-based, not a model's opinion. Same logic
• payment_decision ~841 tokens
  Call this before every payment your agent makes. Free, no signup, no API key. To see it work first, call it with {"to":"0xd90e2f925DA726b50C4Ed8D0Fb90Ad053324F31b","network":"ethereum"}: that address is a known mixer, so the answer is decline with the matching list as evidence. Pass the payee addres
• recent_flagged ~86 tokens
  Return a representative sample of addresses on OceanAlt's reviewed risk list — OFAC-sanctioned, known mixers, and scam/phishing — each with its source category and reason. Takes no arguments. Free, no API key.
• resolve_agent_identity ~180 tokens
  Resolves who stands behind a paying agent: agent -> principal -> mandate -> credential -> wallet. Each link reports whether it holds; completeness counts how many do (a factual count, not a score). Wherever the chain breaks is where accountability stops. Publication is opt-in and only posture is exp
• screen_address ~460 tokens
  Run an AML compliance screen on a single blockchain address BEFORE paying or receiving from it — the pre-payment check on a counterparty. Checks OFAC sanctions, known mixers, scam and phishing lists, stablecoin issuer freezes, and on-chain heuristics. Returns a verdict (clear | caution | risky), a 0
• screen_endpoint ~323 tokens
  Screen a payment ENDPOINT (URL or domain) before calling it — the half that address screening cannot answer. In x402 the agent discovers a URL first, receives a 402, and only then learns where to pay: if that endpoint is spoofed, the payee address it hands back is freshly generated and appears on no
• verify_payment_requirements ~357 tokens
  Before paying an x402 402 response, check that its payment requirements (payTo, amount, asset, network, resource) were signed by the seller and not altered in transit by a proxy, CDN, SDK or another tool. x402 v2 carries the requirements in the PAYMENT-REQUIRED response header (base64 JSON): pass ei
