payment_decision

Call before sending funds, buying a service, settling an invoice or answering an x402 payment quote. Pass the payee address (to) and network to get allow | review | decline, evidence and retry semanti…

screen_address

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, …

screen_endpoint

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:…

check_payment_request

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 addr…

counterparty_control_baseline

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. Return…

attest_control_baseline

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 payer…

baseline_controls

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_base…

resolve_agent_identity

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). Wh…

recent_flagged

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…

verify_payment_requirements

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 t…

check_calldata_intent

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…

payee_decide

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 c…

evidence_bundle

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 li…

check_before_paying

Run OceanAlt's pre-payment checks in the right order before any money moves: payee, payment page, and the message that asked for payment.
