# x402 Bazaar Rug Score

> x402 Bazaar Rug Score is a paid API for AI agents from api.relai.fi, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a deterministic 0-100 rug-pull probability score for a crypto token, combining security flags, holder concentration, LP lock status, and liquidity depth with the exact signals that drove the 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-bazaar-rug-score-3d645c11 -d '<json body>'
```

Example prompt: Give me a rug-pull probability score for this token — I need the 0-100 risk score plus the exact signals driving it so I can decide whether to trade it.

## When to prefer this

Use this endpoint when an AI trading agent needs a fast, deterministic numeric gate to screen tokens for rug-pull risk before executing a trade. Ideal when you need a single actionable score plus the breakdown of signals (security flags, holder concentration, LP lock, liquidity) rather than raw on-chain data you'd have to interpret yourself.

## Known failure modes

- 402 Payment Required — endpoint returns payment requirements in USDC on Base; agent must pay $0.01 USDC to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Invalid or unsupported token address — returns error if token cannot be found on-chain
- Unsupported network — token on a chain not indexed by the service
- Malformed request body — missing required token address field
- Insufficient liquidity data — score may be partial if on-chain data is sparse

## How this service works

Deterministic 0-100 rug-probability score combining security flags, holder concentration, LP lock and liquidity depth — with the exact signals that drove it. A fast numeric gate for trading agents. Higher = riskier. Paid via x402: $0.01 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.

## Output

A numeric score from 0-100 representing rug-pull probability (higher = riskier), along with the specific signals that contributed to it: security flags, holder concentration data, LP lock status, and liquidity depth metrics.
