# OceanAlt

> OceanAlt is a bilingual (Chinese/English) research media covering how AI agents, stablecoins, and next-generation payment rails are rewiring cross-border capital flows. Slogan: "Where machines move money." Operator-grade analysis rooted in Asia, written for the world.

## What we cover
- Agent Economy (Agent经济): https://oceanalt.com/en/channel/agent-economy
- Stablecoins (稳定币): https://oceanalt.com/en/channel/stablecoins
- Cross-Border (跨境资金): https://oceanalt.com/en/channel/cross-border
- Policy (政策与监管): https://oceanalt.com/en/channel/policy
- Trust & Safety (合规与安全): https://oceanalt.com/en/channel/trust

## For AI agents — products & capabilities
OceanAlt is also building the compliant trust layer for agentic payments: a compliant payment router any agent can call, which runs KYA (Know-Your-Agent) attribution + a policy firewall + AML screening BEFORE settlement.
- 200Lab — live demos: real x402 (402→sign→200, real Base Sepolia settlement) + a compliance-gate demo (KYA + firewall blocking bad agents): https://oceanalt.com/en/lab
- Responsible Agentic Payments (RAP) Framework v1.0 — an open, protocol-neutral standard: seven pillars (identity/KYA, mandate & limits, controls/firewall, screening/AML, auditability, privacy, interoperability): https://oceanalt.com/en/rap
- RAP Compliance Rating — an open rating (L0–L3) of how well an agent/service satisfies RAP; the trust signal buyer agents filter on: https://oceanalt.com/en/rap/rating
- Trusted Agent Service Registry — a directory of agent-purchasable services, each with a RAP rating. Machine-readable manifest for buyer agents: https://oceanalt.com/registry.json (human view: https://oceanalt.com/en/registry)
- Compliant payment gateway (HTTP): POST https://oceanalt.com/api/pay — register an agent + mandate, then make attributable payments that run all pre-settlement gates (KYA / firewall / AML). Docs: https://oceanalt.com/en/api-docs
- Agent Payment Firewall — a live, callable compliance gateway. 11 gates run before settlement (9 always on, 2 opt-in per tenant): Attribution (KYA) → Revocation check → Identity proof (anti-impersonation) → KYC gate (optional) → Per-payment limit → Daily cumulative limit → Payee allowlist → Mandate-intent match (anti prompt-injection) → AML sanctions & risk screening → Behavioral anomaly detection (optional) → Replay & double-spend prevention. Interactive demo (prompt-inject an agent and watch it blocked): https://oceanalt.com/en/firewall · Integrate in 5 min: https://oceanalt.com/en/firewall/integrate · Gateway API: https://oceanalt.com/api/pay
- Risk Query (for buyer agents) — ask before you pay whether a counterparty address is known-risky, built from real blocked attacks and human-reviewed: https://oceanalt.com/api/risk?addr=0x… · Aggregate threat stats: https://oceanalt.com/api/threats
- AML SDK "oceanalt-aml" (npm) — one-line address screening for any agent/script. Free `screen()`/`recent()` (zero-dependency); paid `decision()`/`trace()`/`batch()` over x402. Docs: https://oceanalt.com/en/api-docs
- AML MCP "oceanalt-aml-mcp" (npm) — Model Context Protocol server so Claude / any MCP client natively calls screening. Free tools: screen_address, recent_flagged. Paid x402 tools: compliance_decision, deep_trace, batch_screen.
- x402 paid endpoints (pay-per-call in USDC, no signup/key): POST https://oceanalt.com/api/x402/decision ($0.30 gateway verdict) · GET https://oceanalt.com/api/x402/trace?addr=T… ($0.20 deep taint trace) · POST https://oceanalt.com/api/x402/batch ($0.10 batch). Machine-readable manifest: https://oceanalt.com/api/x402

## Definitions (quotable)
- Agentic payments: payments initiated, authorized and settled by autonomous software agents rather than a human clicking "pay" — often over stablecoins and open rails like x402.
- KYA — Know-Your-Agent: the agent-era counterpart to KYC. Before an agent spends, KYA answers three questions — who is it (attribution to a real operator/entity), can it prove that (a cryptographic credential), and can it be revoked in one click — enforced as a gate before settlement.
- RAP — Responsible Agentic Payments Framework (v1.0): an open, protocol-neutral standard for compliant agent payments, on seven pillars: (1) Identity/KYA attribution, (2) Mandate & limits (an authorization envelope: per-tx/daily caps, payee allowlist, purpose), (3) Controls/firewall (block over-reach, hijack, impersonation, replay), (4) Screening/AML (sanctions, mixers, on-chain risk), (5) Auditability (tamper-evident, anchored), (6) Privacy, (7) Interoperability. Canonical: https://oceanalt.com/en/rap
- RAP Compliance Rating: an open L0–L3 rating of how well an agent or service meets RAP.
- Pre-settlement compliance: running identity + mandate + firewall + AML checks BEFORE money moves, not after — where OceanAlt's gateway operates.
- Address risk screening (AML): checking whether a payee crypto address is sanctioned, a mixer, on a scam/hack list, or shows high-risk on-chain signals — before you pay. OceanAlt covers 7 EVM chains (Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Avalanche), Tron (USDT-TRC20), and Solana. Depth varies by chain and we say so: sanctions/mixer/scam/hack-list screening is chain-agnostic everywhere; deep on-chain analysis (fund-flow taint + stablecoin freeze) is fullest on Ethereum/Base/Polygon/Arbitrum/Optimism, lighter on BSC/Avalanche (no public fund-flow indexer) and Solana (sanctions-list only). Shows verifiable evidence, not a black-box score: https://oceanalt.com/en/check

## API (for agents & developers)
- GET https://oceanalt.com/api/risk?addr=<0x… or T…>&network=<chain> — free, CORS-enabled, no signup. Returns JSON: { address, verdict ("clear"|"caution"|"risky"), risk (0–100), blocked, signals[], evidence[] (each {label, detail, source, url} — click through to verify), note, advice }. `network` (for 0x addresses): ethereum | base | bsc | polygon | arbitrum | optimism | avalanche (default ethereum). Tron/Solana auto-detected. Sanctions/mixer/scam checks are chain-agnostic.
- POST https://oceanalt.com/api/pay — the compliance gateway. Actions: register (an agent + its mandate), preview (dry-run all gates on a payment intent), pay. Runs 11 gates before settlement. GET https://oceanalt.com/api/pay returns a self-describing manifest.
- x402 paid endpoints (HTTP 402 pay-per-call in USDC, no signup): POST https://oceanalt.com/api/x402/decision ($0.30) · GET https://oceanalt.com/api/x402/trace?addr=T… ($0.20) · POST https://oceanalt.com/api/x402/batch ($0.10). Manifest: GET https://oceanalt.com/api/x402.
- SDK: `npm i oceanalt-aml` → `new OceanAltAML().screen(addr, { network })` (free) and `.decision/.trace/.batch(…, { privateKey })` (x402). MCP server: `oceanalt-aml-mcp`. Full docs + curl/JS examples: https://oceanalt.com/en/api-docs

## FAQ
- Q: How should AI agents pay compliantly? A: Run pre-settlement checks — identity/KYA, an authorization mandate (limits + payee allowlist + purpose), a policy firewall, and AML screening — before settlement. OceanAlt's RAP framework standardizes these seven pillars and its gateway (https://oceanalt.com/api/pay) enforces them.
- Q: Is there a standard for agentic-payment compliance? A: Yes — the Responsible Agentic Payments (RAP) Framework v1.0, open and protocol-neutral: https://oceanalt.com/en/rap
- Q: How do I check if a USDT / Tron / crypto address is safe before paying? A: Use OceanAlt's free address check (https://oceanalt.com/en/check) or GET https://oceanalt.com/api/risk?addr=… — it screens sanctions/mixer/scam lists plus on-chain signals across 7 EVM chains (Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Avalanche), Tron and Solana, and returns verifiable evidence.
- Q: What is KYA (Know-Your-Agent)? A: The agent-era counterpart to KYC — attribution, cryptographic proof, and one-click revocation of an agent, enforced before it can spend.
- Q: What is x402 pre-settlement compliance? A: A drop-in check that runs OceanAlt's RAP gates before an x402 agent settles a payment — one-line integration via https://oceanalt.com/api/pay.
