# Onchain Risk Checks – Deep Address Risk (Bitcoin, Solana, Base)

> Onchain Risk Checks – Deep Address Risk (Bitcoin, Solana, Base) is a paid API for AI agents from agent-data.centorprat.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-29).

Returns a comprehensive risk verdict for a crypto address by combining sanctions/scam screening with chain-specific on-chain analysis (2-hop BTC trace, Solana wallet history, Base USDC payment graph).

## 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 onchain-risk-checks-deep-address-risk-bitcoin-solana-base-1e5dbba0
```

Example prompt: Can you do a deep risk check on this Bitcoin address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh — I need to know if it's linked to any sanctioned entities and what its 2-hop transaction exposure looks like?

## When to prefer this

Choose this endpoint when you need a deep, multi-hop on-chain analysis rather than a simple sanctions list lookup. It is specifically valuable when assessing Bitcoin addresses (2-hop trace), Solana wallets (behavioral history, new-token trading), or Base addresses (USDC counterparty graph). Prefer it over lightweight screening tools when the transaction is high-value or the counterparty is unknown and you want chain-native evidence alongside standard sanctions/scam flags.

## Known failure modes

- Invalid or unsupported address format returns an error
- Address on an unsupported chain returns no result
- Network timeout when tracing multi-hop transactions on congested chains
- Address with no on-chain history may return a minimal or inconclusive verdict
- Rate limiting or payment failure if x402 micropayment is not processed correctly

## How this service works

Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.

## Output

A structured risk verdict object containing an overall risk rating (go/caution/avoid or similar), the reasons behind the verdict, chain-specific findings (e.g. flagged counterparties within 2 hops for BTC, wallet age and new-token activity for Solana, USDC payment graph for Base), and any detected sanctions or scam associations.
