## 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 synapse-token-price-lookup-69c3cfaf
```

Example prompt: What's the current USD price of Solana?

## When to prefer this

Use this endpoint when you need a quick, low-cost per-call USD price for a named cryptocurrency token without needing an API key or account. Ideal for agents making ad-hoc price checks or enriching data pipelines with crypto prices on demand. Prefer this over subscription-based crypto data APIs when you only need occasional lookups and want to pay per call in USDC via x402.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty response
- Misspelled token name may return no result or incorrect data
- Network or upstream data provider unavailability causes request failure
- Payment failure via x402 protocol prevents request from completing
- Token name ambiguity (e.g. multiple tokens with same ticker) may return unexpected result
