# ERC-20 Token Risk & OFAC Screening Endpoint

> ERC-20 Token Risk & OFAC Screening Endpoint is a paid API for AI agents from x402helper.xyz, paid per call via x402, $0.026/call, status unknown (last checked 2026-10-31).

Returns OFAC sanctions screening, risk assessment, and rate/billing data for an ERC-20 token contract address on a specified EVM network.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability erc-20-token-risk-ofac-screening-endpoint-e446db41
```

Example prompt: Can you run an OFAC sanctions and risk check on the token contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on the Ethereum network?

## When to prefer this

Choose this endpoint when you need a single API call that combines OFAC sanctions screening, risk rating, and billing/rate data for an ERC-20 token contract on EVM networks including Base, Ethereum, Arbitrum, Optimism, or Polygon. Prefer it over manual blockchain lookups or separate compliance APIs when building AI agents that need automated, pay-per-use token compliance checks via x402 micropayments.

## Known failure modes

- Invalid or malformed token contract address returns an error
- Unsupported network value outside allowed enum causes rejection
- Payment not completed (x402 flow failure) blocks response
- Token contract not found on specified network may return empty or error result
- Rate limiting or upstream data unavailability may cause failures

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object with a 'success' boolean and a 'result' object containing OFAC screening status, risk assessment data, token rates, and billing verification details for the queried token contract on the specified EVM network.
