## 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`):

Example prompt: What's the current spot price of Bitcoin in USD right now?

## When to prefer this

Prefer this endpoint when you need a lightweight, no-account, pay-per-call live crypto spot price lookup settled instantly via USDC on Base using the x402 protocol. It is ideal for AI agents that need real-time price data without API key management or subscriptions. Choose this over exchange REST APIs when you want frictionless micropayment-based access and Coinbase-sourced spot pricing.

## Known failure modes

- Payment not settled via x402 — returns HTTP 402 with payment required headers
- Unsupported trading pair or symbol — may return an error or empty result
- Coinbase spot feed temporarily unavailable — upstream data source error
- Malformed request parameters — returns 400 bad request
- Micro-payment USDC balance insufficient — x402 facilitator rejects transaction

## How this service works

Agent-native micro APIs: hourly-refreshed feed of funded crypto bounty opportunities, GitHub repository honeypot trust scoring, live crypto spot prices and web page reading. Payment via x402 protocol (HTTP 402), USDC on Base (eip155:8453). x402 v1 and v2 compatible; instant settle via Coinbase CDP facilitator. No accounts, no API keys.

## Output

A JSON object containing the base asset (e.g. 'BTC'), the quote currency (e.g. 'USD'), the current spot price as a float, the trading symbol (e.g. 'BTC-USD'), and the data source identifier ('coinbase-spot').
