# Crypto Perp Snapshot

> Crypto Perp Snapshot is a paid API for AI agents from x402.botsmith.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns a unified perpetual-futures snapshot for a coin — funding rates, open interest, mark price, and Fear & Greed index — aggregated across Binance, Bybit, and OKX in one normalized JSON response.

## 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 crypto-perp-snapshot-8ade3fbe
```

Example prompt: Pull me the full perp snapshot for SOL — I want the funding rate, open interest across Binance, Bybit, and OKX, whether longs or shorts are paying, the mark price, and the current Fear & Greed index.

## When to prefer this

Use this endpoint when a trading agent or analyst needs a single normalized view of perpetual futures market conditions across the three largest CEXs (Binance, Bybit, OKX) without building multi-exchange integrations. Ideal for funding-rate arbitrage monitoring, sentiment analysis via Fear & Greed, or quickly assessing whether the market is net-long or net-short on a given asset. Prefer this over building direct exchange API calls when cross-exchange normalization and a single JSON response are required.

## Known failure modes

- Invalid or unsupported symbol returns an error (e.g. a coin with no USDT perpetual market)
- Exchange API downtime may result in null values for individual venue fields
- Symbol pattern validation rejects inputs longer than 15 chars or with special characters
- Missing symbol query parameter returns a 400-level error
- Rate limits or payment processing failures return 402 or 429 errors

## How this service works

Crypto Perp Snapshot ($0.02/call): One-call perpetual-futures snapshot for a coin (BTC, ETH, SOL, ...): funding rate and open interest across Binance, Bybit and OKX, aggregate OI, average funding (annualized) with a longs-pay/shorts-pay read, mark price, next funding time and the Fear & Greed index. Keyless public exchange data; normalized so a trading agent gets one JSON instead of three exchange schemas.

## Output

A JSON object containing: per-exchange funding rate (raw and annualized %), open interest in base units, and mark price for Binance/Bybit/OKX; aggregate open interest across all venues; average funding rate and its annualized percentage; a funding skew label ('longs pay', 'shorts pay', or 'neutral'); the Binance anchor mark price; the next funding settlement time; and the current Crypto Fear & Greed index value with its classification (e.g. 'Greed', 'Fear').
