# Tanod chainpeek Sanctions Screening

> Tanod chainpeek Sanctions Screening is a paid API for AI agents from tanod.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

Screens a single crypto address against the US OFAC SDN digital-currency-address list and returns whether it is sanctioned as of the list date.

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 tanod-chainpeek-sanctions-screening-a3269f19 -d '<json body>'
```

Example prompt: Can you check if the Ethereum address 0x1234567890abcdef1234567890abcdef12345678 is on the OFAC SDN sanctions list before I send funds to it?

## When to prefer this

Use this endpoint when you need a fast, low-cost, single-address screen against the US OFAC SDN digital-currency-address list specifically. It is ideal for pre-transaction compliance checks in crypto workflows, DeFi onboarding, or automated monitoring where you need a quick sanctions hit/no-hit result. Prefer this over broader KYC/AML services if you only need OFAC SDN coverage for a single address at minimal cost ($0.002 per call). Not a substitute for full compliance programs or legal counsel.

## Known failure modes

- Invalid address format (does not match the allowed character pattern or length) — returns a validation error
- Address not found in the OFAC list — returns a clean/no-match result (not an error)
- OFAC list data unavailable or stale — may return an error or indicate list_date is outdated
- Malformed request body — returns a schema validation error
- Rate limiting or payment failure — returns a 402 or 429 error

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns whether the submitted crypto address appears on the US OFAC SDN digital-currency-address list, along with the list_date (the date of the SDN list version checked) and any relevant SDN entry details if a match is found. This is a screening aid and not a full compliance determination or legal advice.
