## 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-agent-store-crypto-token-prices-091ab877
```

Example prompt: What are the current USD prices for bitcoin, ethereum, and solana right now, with confidence scores?

## When to prefer this

Use this endpoint when you need live USD price data for one or more specific tokens identified by their CoinGecko IDs in a single call, especially when you want confidence scores alongside prices and attribution to DefiLlama. Prefer this over generic price APIs when operating in a DeFi/agent context that supports x402 micropayments.

## Known failure modes

- Invalid or unrecognized CoinGecko ID returns an error or missing entry for that token
- Requesting more than 25 token IDs returns a validation error
- DefiLlama data source unavailable causes a 503 or stale-data response
- Malformed comma-separated ids parameter returns a 400 bad request
- Payment not processed (x402 payment required) results in a 402 error

## How this service works

Current USD prices for one or more tokens by CoinGecko id (e.g. bitcoin, ethereum, solana, usd-coin). Returns price, symbol, and confidence per token in one call. Sourced live from DefiLlama with attribution.

## Output

A JSON object mapping each requested CoinGecko token ID to its current USD price, token symbol, and a confidence score indicating data reliability, plus a source attribution string (DefiLlama).
