# Tanod chainpeek Batch Sanctions Screening

> Tanod chainpeek Batch Sanctions Screening is a paid API for AI agents from tanod.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Screens 1–1,000 crypto addresses in a single call against the US OFAC SDN digital-currency-address list and returns per-address match results.

## 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-batch-sanctions-screening-d133099a -d '<json body>'
```

Example prompt: Can you check these two Ethereum addresses against the OFAC sanctions list: 0x098B716B8Aaf21512996dC57EB0615e2383E2f96 and 0x0000000000000000000000000000000000000001?

## When to prefer this

Use this endpoint when you need fast, low-cost batch OFAC SDN screening for crypto addresses (EVM, bech32, BTC, TRX, etc.) and want a per-address match result with program and entity name details. Prefer it over manual OFAC lookups when screening many addresses programmatically. Note its scope is limited to the OFAC SDN digital-currency-address list only — it does not cover other sanctions lists, perform clustering, or analyze address exposure.

## Known failure modes

- Invalid address format — addresses not matching the allowed pattern are rejected
- Empty or missing addresses array returns a validation error
- Exceeding 1,000 addresses per call returns an error
- Payment failure (x402) if USDC balance is insufficient
- OFAC list source temporarily unavailable causing upstream fetch errors
- Stale list_date if the upstream OFAC publication has not been refreshed

## 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

A JSON object containing the list name, source URL, list date, total address count in the SDN list, and a per-address results array. Each result includes the input address, a boolean matched field, address_kind (e.g. 'evm'), and a matches array with sdn_uid, currency, programs, sdn_name, sdn_type, and the listed_address for any hits. Also includes a matched_count summary and a disclaimer clarifying the screening scope.
