DEVELOPER TOOLS

For Developers & Agents

Three ways to add a pre-payment compliance check to your app or agent. The free tools need no signup and no key.

1

Free address screening (REST)

One line to ask “is this payee address safe?” — returns a verdict + risk score + verifiable evidence (not a black-box score). No key.

curl "https://oceanalt.com/api/risk?addr=0x8589427373D6D84E98730D7795D8f6f8731FDA16"

That address is Tornado Cash (OFAC-sanctioned) — it returns risky.

2

Drop into your AI (MCP)

Let Claude / Cursor / any MCP client call compliance screening natively. Add it to your MCP config:

① stdio (npm package)

{
  "mcpServers": {
    "oceanalt-aml": { "command": "npx", "args": ["-y", "oceanalt-aml-mcp"] }
  }
}

② Remote endpoint (no install, for remote-MCP clients)

https://oceanalt.com/api/mcp

Free tools: screen_address, recent_flagged (no key).

3

Let agents pay per call (x402)

Paid endpoints per call (USDC on Base): gateway decision / deep trace / batch. An agent signs one wallet authorization to pay — no signup. Machine-readable manifest:

curl https://oceanalt.com/api/x402
  • · POST /api/x402/decision — gateway compliance decision · $0.30
  • · GET /api/x402/trace — multi-hop taint trace · $0.20
  • · POST /api/x402/batch — batch screen (≤25) · $0.10
