## 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 santyvv-data-crypto-search-api-x402-bc0e03ce
```

Example prompt: Search for the cryptocurrency 'Chainlink' and give me its token symbol and any market data you can find — no API key needed, just pay per call.

## When to prefer this

Choose this endpoint when you need quick, keyless crypto token search without signing up for accounts or managing API keys. Ideal for agents that need to pay per query in USDC on Base via x402 protocol. Best for lightweight token discovery and metadata lookup rather than deep historical analytics.

## Known failure modes

- Payment not received or USDC balance insufficient — 402 Payment Required returned
- Invalid or empty search query — may return empty results or 400 error
- Token not found in data sources — empty result set returned
- Rate limiting or upstream provider outage — may return 503 or degraded fallback data
- Network timeout on edge cache miss — slow response or timeout error

## How this service works

Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.

## Output

Returns a normalized JSON response containing matching cryptocurrency assets for the search query, including token names, symbols, and available market or on-chain metadata aggregated from public data providers with edge-cached results.
