What OceanAlt is and how to call it

OceanAlt is the compliance layer for agent payments: it answers whether a payment should happen, before the money moves.

Screen a payee address with one call, no signup and no API key: GET https://oceanalt.com/api/risk?addr=0x…; returns verdict (clear|caution|risky|uncertain), risk 0-100, language-independent signal_keys, and evidence with source URLs.

Three access levels, all opt-in: anonymous (60/min and 2,000 calls a month free, no signup); registered (180/min and 5,000 calls a month free: POST /api/access-keys with an email); KYA (300/min and 50,000 a month free. Call with a registered agent credential). With a key or KYA credential, going past the allowance only slows you down; anonymous callers past the allowance get 402 on decisions, address screening and payee checks (pay per call or get a free key). An unrecognised credential is never silently downgraded: the response says key_rejected and why.

Also available as an npm SDK (oceanalt-aml), an MCP server (npx oceanalt-aml-mcp, registry com.oceanalt/aml), a Telegram bot (@OceanAltTrust_Bot), and an embeddable widget.

The pre-payment check runs 15 checks before settlement (11 of them in the payment gateway): attribution, mandate limits, payee allowlist, AML screening, payment page, payment request, payee continuity, replay protection and more.

Machine-readable capability list: https://oceanalt.com/.well-known/agent-capabilities. It also states what OceanAlt cannot do.

Important boundary: a verdict of "clear" means nothing was found in the data held, not that an address is safe. Absence of evidence is not evidence of safety.

The future of money will increasingly move through Agents.

11 of these are the payment gateway's gates; KYC and behavior anomaly are off by default and switched on per customer. Payment request, payment page, payee continuity and evidence freshness come from the pre-payment decision API. The replay shows both layers on one line.Try a payment yourself →

Trading, payments and financial services7 scenarios

Pre-trade checks in OTC

Over-the-counter trades where a counterparty sends you an address before you move.

Receiving tainted funds, a later exchange freeze, and no answer for where the money came from.

Trace the funds and taint →

Deposit screening for exchanges & dApps

Exchanges, dApps and projects, at the moment a user deposit lands.

Taking in stolen or mixer-routed funds, then facing freezes and questions with nothing to show the user.

See how deposit screening works →

Pre-send checks inside a wallet

Wallet and front-end developers, the half second before a user hits Send.

A user pays a phishing address and blames the wallet first. The free check takes one line of code.

One line, free API →

Outbound checks for trading bots

Quant and on-chain strategies, right before a bot pays a counterparty or withdraws to the main wallet.

A counterparty got listed yesterday and nobody noticed; one transfer can drag the whole account into a compliance incident.

Machine-readable /api/decide →

Cross-border procurement & trade settlement

Trade and e-commerce teams settling suppliers in stablecoins, or a procurement agent ordering on rules.

A supplier's payout address changed unnoticed, an over-budget order, a duplicate payment same day.

Turn the rules into a mandate →

Treasury and multisig pre-flight

A DAO treasury or corporate multisig, after approval and before signing.

A swapped payout address, a sanctioned recipient, discovered only after signing.

Check before you sign →

Pre-settlement screening for a PSP

A payment gateway or crypto acquirer that needs AML before settlement.

No evidence when a regulator asks, a silent pass when screening fails, an inconsistent verdict.

Binance Sets Aside $6.34B to Cover Hack Losses; Attack Chain Exposes Account Abstraction Authorization Blind Spot

Binance says it has earmarked $6.34 billion to cover hacker losses and stresses user asset safety; technical details point to self-destruct mechanisms and EIP-7702 delegation bypassing approvals, offering a real-world sample for authorization boundaries in agent payments.

Beyond the Binance Security Incident: Why AI Payments Need a New Line of Defense

The Binance security incident reminds the market that the absence of direct private key theft does not mean there are no risks in the fund execution environment and business authorization. Today, RMB, USD, and EUR payment systems process hundreds of millions to billions of non-cash transactions daily, while on-chain transfers of USDT and USDC have reached tens of millions per day. Facing higher-frequency, more automated payments, OceanAlt explores adding an independent trust judgment before payment through KYA, authorization limits, payee risk screening, and verifiable decision evidence.

Tempo's official blog details API monetization models and proposes the MPP protocol, which lets AI agents pay directly at request time—bypassing account opening and subscriptions—and provides a machine-readable payment path for per-call billing.

Kaiko data shows USDC's share of euro stablecoin trading rose from 10% in January 2024 to 56%, with euro-denominated order book depth about 40% higher than USDT; the EBA's 'significant e-money token' designation and the trading share flip occurred almost simultaneously, as regulatory classification becomes a direct variable in market structure.

Cross-Border Payment Data Meets AI Agents: A Ground-Level Case for the Settlement Chain

Cross-border payment data is beginning to be exposed to AI agents via APIs, moving agents from 'reading data' to 'participating in the settlement chain'—and exposing gaps in data interfaces, authorization, and risk controls.

Mastercard Brings Agent Payments into Its Card Network: The Battle for the $80 Trillion B2B Market

Card networks are no longer just conduits; they are embedding agent authorization, credentials, and settlement into existing networks. For agent payment firewalls, the identity and authorization layers are being pushed forward to the issuing side.
