## 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 coinbase-exchange-products-lookup-5db411dc
```

Example prompt: Can you fetch all Coinbase Exchange trading pairs quoted in EUR — get me up to 100 of them?

## When to prefer this

Choose this endpoint when you need a current, authoritative list of tradable products on Coinbase Exchange without managing API keys or accounts. Ideal for agents that need to enumerate available markets, validate whether a specific trading pair exists, or build dynamic UIs around Coinbase Exchange offerings. Prefer it over direct Coinbase API calls when pay-per-use micropayment billing (x402/USDC) is preferred over key management.

## Known failure modes

- Invalid quote currency string returns an empty product list or error
- Limit value outside 1–200 range may be rejected or clamped
- Payment failure (insufficient USDC balance) results in a 402 response with no charge
- Upstream Coinbase Exchange API downtime causes proxy error or stale data
- Network timeout on the Cloudflare worker may return a 5xx error

## How this service works

Coinbase Exchange trading products (pairs) with status and minimum order sizes, filtered by quote currency (default USD). Lists what can be traded; no prices.

## Output

A JSON object containing the requested quote currency, source URL, a list of trading pair objects (each with ID, base, quote, status, quote increment, and trading-disabled flag), the timestamp the data was fetched, and the total number of products available for that quote currency.
