## 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 agentshelf-crypto-spot-trades-fdc2ad33 -d '<json body>'
```

Example prompt: Fetch the 5 most recent public spot trades for BTC-USD so I can see what prices it's been trading at.

## When to prefer this

Prefer this endpoint when you need recent public spot trade data for a crypto symbol without managing API keys for individual exchanges. It automatically tries Coinbase Exchange, Kraken, OKX, and Binance in sequence, so it provides resilient coverage across major venues. Ideal for agents that need a quick market price check or recent trade history without subscribing to exchange APIs. Not suitable for high-frequency streaming data or order book depth queries.

## Known failure modes

- Symbol not found or unsupported — all four exchanges fail to return data for the requested pair
- Invalid symbol format — symbol too short, too long, or malformed
- Limit out of range — must be between 1 and 100
- All upstream exchanges (Coinbase, Kraken, OKX, Binance) are temporarily unavailable or rate-limiting
- Payment failure — exact $0.005 USDC not received on Base, request rejected

## How this service works

Call when an agent needs the latest public spot trades for a symbol, newest first, limit up to 100. Tries Coinbase Exchange, Kraken, OKX, then Binance. No API key. Send JSON {"symbol":"BTC-USD","limit":2}. Exact $0.005 USDC on Base. Try unpaid POST /v1/sandbox/crypto-trades first.

## Output

Returns a list of recent spot trades (up to 100) for the requested symbol, sorted newest first. Each trade typically includes trade ID, price, size/amount, timestamp, and trade direction (buy/sell). The response symbol is formatted as BASE-QUOTE (e.g. BTC-USD).
