## 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 crucible-finance-quote-token-price-lookup-d3c01c61 -d '<json body>'
```

Example prompt: What's the current USD price of the USDC token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and the WETH token at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2? Give me the prices with confidence scores and your sources.

## When to prefer this

Choose this endpoint when you need cited, verifiable token price data with confidence scoring for one or more ERC-20 tokens or native ETH — especially in agentic workflows where auditability and source attribution matter. Prefer over generic price APIs when you need on-chain evidence, risk scores, or a content hash for tamper-evidence.

## Known failure modes

- Invalid or non-existent contract address returns null USD price for that token
- Unrecognized token contract may return low confidence score
- Network/RPC issues may cause partial results or timeout
- Malformed request (missing tokens array) returns validation error
- Token with no on-chain liquidity data may have null price

## How this service works

Pay-per-call Web3 agent services: wallet, token and agent security audits; token prices, depeg checks and portfolio valuation; cited fact-checking and source research.

## Output

Returns an object with a prices array containing the USD price for each requested token, plus a confidence score, risk score, content hash for verifiability, and arrays of cited sources (with URLs and hashes) and evidence claims linking each price to its supporting sources.
