## 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 usenami-perp-snapshot-86f9405f
```

Example prompt: Give me a full market snapshot for the BTC-PERP on Binance — I need the current funding rate, annualized carry, open interest, 24h volume, and mark price all in one shot.

## When to prefer this

Use this endpoint when you need a comprehensive, single-call snapshot of all key perpetual futures market metrics (funding, carry, OI, volume, mark price) for a specific venue/ticker pair, rather than making multiple separate API calls. It is ideal for pre-trade checks, carry farming scans, or real-time position monitoring where latency and call efficiency matter. Prefer it over individual metric endpoints when you need all metrics simultaneously.

## Known failure modes

- Unsupported ticker or venue returns an error or empty result
- Stale data if the venue feed has a temporary gap
- Malformed input schema (missing type or method fields) returns a 400-level error
- Rate limiting or payment failure (x402) if USDC payment is not processed correctly
- Venue temporarily offline or data unavailable returns partial or null fields

## How this service works

One-call market snapshot for one crypto perpetual across every tracked venue — funding rate, annualized carry with contango/backwardation structure, open interest, 24h volume and mark price in a single response. Bundles funding/carry/open-interest/volume-24h so an agent makes one paid call instead of four.

## Output

A bundled JSON object containing the current funding rate, annualized carry and carry structure, open interest, 24-hour trading volume, and mark price for the specified perpetual futures ticker and venue — all returned in a single API response.
