## 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-seller-onchain-token-lookup-32ec8955
```

Example prompt: Can you look up the on-chain token data for the contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — give me its current price and pool info?

## When to prefer this

Use this endpoint when an AI agent needs a quick, keyless on-chain token data lookup without stitching together multiple free APIs. Ideal when you already have a contract address or token name and need price or pool data on a specific chain, and are paying per-call in USDC via x402.

## Known failure modes

- Token address not found on specified chain — returns empty or error object
- Invalid or unsupported chain identifier — returns error
- Ambiguous query string with no matching token — returns no results
- Upstream on-chain data provider unavailable — service timeout or 5xx error
- Payment not included or insufficient USDC — HTTP 402 response

## How this service works

Rug protection and decision-ready intelligence for autonomous trading agents. Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).

## Output

Returns an object containing on-chain token data for the queried token, which may include current price, DEX liquidity pool details, token metadata, and other chain-specific information relevant to the token.
