## 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 47620-crypto-orderbook-api-3db0c199
```

Example prompt: What's the current top-of-book for BTC — give me the best bid and ask, the spread in bps, and whether the book is bid- or ask-heavy right now.

## When to prefer this

Choose this endpoint when you need real-time top-of-book market microstructure data (bid/ask/spread/depth/imbalance) for a cryptocurrency without needing an API key or account — particularly when paying per-call via x402/USDC is acceptable and you want no subscription overhead. Prefer over centralized exchange APIs when you need a keyless, on-chain-payment model compatible with autonomous agents.

## Known failure modes

- Invalid or unsupported symbol returns an error response
- Payment not received or underpaid results in 402 Payment Required
- Network or upstream exchange outage may return stale or empty data
- Malformed symbol path parameter yields 400 or error JSON
- Rate limit or on-chain confirmation delay may cause latency spikes

## How this service works

Non-custodial x402 payment gateway on Solana (1% on-chain fee) plus a pay-per-call Solana data API for agents: token price, account balances, tx lookup, trending DEX pairs, network health. No signup, no API key — pay USDC per call.

## Output

Returns a JSON object with ok status, fetchedAt timestamp, and a data block containing best bid price, best ask price, mid price, absolute spread, spread in basis points, bid-side depth, ask-side depth, and a book imbalance metric indicating directional pressure.
