# SpendTheBits Address Risk Screener

> SpendTheBits Address Risk Screener is a paid API for AI agents from x402.spendthebits.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

Returns a sanctions/scam screening verdict and verified-token-contract status for a given blockchain address, mirroring the risk gate used in the STB wallet.

## 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 spendthebits-address-risk-screener-0687fe0b
```

Example prompt: Before I send funds, screen this mainnet address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — is it sanctioned, flagged as a scam, or a verified token contract?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call sanctions and scam screening verdict for a single blockchain address across multiple chains (EVM, Solana, TRON, XRPL, Bitcoin) without setting up a full AML provider integration. Ideal for AI agents that need to gate crypto sends with the same risk logic used by the STB wallet, especially in low-volume or on-demand scenarios where a subscription-based compliance service would be overkill.

## Known failure modes

- Address parameter missing or too short — request rejected with validation error
- Invalid network enum value — returns error or defaults to mainnet
- Address format unrecognized for the specified chain — may return inconclusive result
- Payment not received or insufficient — x402 payment required error
- Network/service unavailable — upstream screening provider timeout

## How this service works

Sanctions/scam screening verdict for one address (?address=, optional ?network=mainnet|testnet) plus whether it is a verified token contract STB recognises. The same screen that gates every send in the STB wallet.

## Output

A JSON verdict indicating whether the address is flagged under sanctions or scam databases, and whether it matches a verified token contract recognized by SpendTheBits — the same risk gate applied to every send in the STB wallet.
