## 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 script-master-labs-crypto-price-api-x402-cecc0062
```

Example prompt: What's the current price of bitcoin and ethereum in USD, including their 24-hour price change and market cap?

## When to prefer this

Choose this endpoint when you need real-time cryptocurrency price data with optional market metrics (market cap, volume, 24hr change) in a pay-per-call model settled in USDC on Base via the x402 protocol — ideal for AI agents that need on-demand spot pricing without a long-term API subscription.

## Known failure modes

- Invalid or unrecognized coin ID returns an empty object or error
- Missing required 'ids' query parameter causes a 400 or schema validation error
- Payment failure or insufficient USDC balance results in x402 payment-required error
- vs_currencies not supported returns empty or error response
- Rate limiting or upstream provider downtime causes 5xx or timeout

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

A JSON object keyed by coin ID, containing the current price in the requested fiat/crypto currency, and optionally the 24-hour trading volume, market capitalization, and 24-hour price change percentage — all as numeric values.
