## 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 x402-data-api-crypto-spot-price-8b884a47
```

Example prompt: What's the current USD price of solana and how much has it changed in the last 24 hours?

## When to prefer this

Use this endpoint when you need a fast, cheap USD spot price and 24-hour change for a single crypto asset by CoinGecko id. Ideal for trading bots, price alert systems, or analytics pipelines that need high-volume, low-cost price lookups without full market data. If you need multi-timeframe changes (1h/7d/30d), market cap, or volume, prefer the sibling enriched market report endpoint instead.

## Known failure modes

- Invalid or unknown CoinGecko coin id returns an error — agent must use exact CoinGecko ids like 'bitcoin', not ticker symbols like 'BTC'
- Payment not fulfilled (x402 micropayment of $0.001 USDC not processed) results in 402 Payment Required response
- Network or upstream CoinGecko API outage may cause 503 or timeout
- Missing required coin query parameter returns a 400 error

## How this service works

Current USD spot price and 24-hour percent change for any crypto asset by CoinGecko id. Cheap, high-volume price lookups for trading and analytics agents.

## Output

Returns a JSON object with the coin's CoinGecko id, current USD spot price as a number, 24-hour percent change as a decimal, and a timestamp of when the data was fetched.
