## 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

```

Example prompt: Can you pull the current market data for Bitcoin and Ethereum — price, volume, and market cap?

## When to prefer this

Choose this endpoint when you need pay-per-call cryptocurrency market data without a subscription, especially in agentic workflows that use x402 micropayments on Base mainnet (USDC). Ideal when you want to avoid API key management and pay only for what you query.

## Known failure modes

- Invalid or unrecognized coin ID returns an error or empty result
- Payment failure over x402 if USDC balance is insufficient
- Rate limiting or rejection if micropayment is not processed correctly
- Network timeout from Cloudflare Workers edge node
- Request for unsupported or delisted coins may return no data

## How this service works

Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).

## Output

Returns market data for the requested cryptocurrency IDs, likely including current price, market capitalization, trading volume, and related reference fields per coin.
