# x402 DeFi Intel – Token Safety Check

> x402 DeFi Intel – Token Safety Check is a paid API for AI agents from cryptodefidataintel-production.up.railway.app, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Analyzes a token contract address on a specified blockchain for safety signals, returning a machine-readable signal, human-readable insight, and confidence score.

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 x402-defi-intel-token-safety-check-25a71d53
```

Example prompt: Is this token safe? Check the token safety for contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — give me the safety signal and how confident you are.

## When to prefer this

Use this endpoint when an agent needs a quick, pay-per-call token safety assessment across multiple EVM-compatible chains before executing a DeFi transaction, and requires both a machine-readable signal and a human-readable explanation with confidence scoring. Prefer this over on-chain analysis tools when you need aggregated multi-source intelligence rather than raw contract bytecode inspection.

## Known failure modes

- Missing required 'chain' or 'token' parameter returns a validation error
- Unsupported chain identifier (not one of base/ethereum/bsc/arbitrum/polygon/optimism/avalanche) returns an error
- Invalid or non-checksummed contract address format returns an error
- Token contract not found or too new to have data returns low-confidence or empty result
- Upstream data sources unavailable returns degraded confidence or partial data
- Payment not processed (x402 flow failure) results in 402 Payment Required response

## How this service works

Crypto-agent toolkit: cross-chain DeFi intelligence + execution helpers + retrieval for agents. 16 endpoints: funding, open interest, long/short, token-safety, yield, prices, gas, tx-simulate, approval-check, bridge-quote, governance-search, lending, liquidations, protocol-search, swap-quote, token-resolve. Pay-per-call via x402.

## Output

Returns an array of result rows with safety data, a machine-readable signal label (e.g. 'safe', 'risky', 'scam'), a human-readable interpretation of the findings, a list of upstream data sources used, a confidence score between 0 and 1, a timestamp, response latency in milliseconds, and the model/rule version used for interpretation.
