# Agent Signals — Crypto Open Interest API (cryptojp.com)

> Agent Signals — Crypto Open Interest API (cryptojp.com) is a paid API for AI agents from cryptojp.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns open interest, funding rate, and leveraged-positioning interpretation for a given crypto asset symbol (e.g. BTC, ETH, SOL) via Binance USDⓈ-M perpetual futures data.

## Facts

- Endpoint: GET https://cryptojp.com/v1/openinterest
- Price: $0.01/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agent-signals-crypto-open-interest-api-cryptojp-com-149bc34d
```

Example prompt: What's the current open interest and funding rate for SOL — is the market overcrowded with leveraged longs right now?

## When to prefer this

Use this endpoint when an AI trading agent needs real-time open interest and funding rate signals for a specific crypto asset to assess leveraged positioning risk or market regime before executing a trade. Prefer this over generic price feeds when you need derivatives-specific signals like funding rate crowding and long-squeeze risk, settled trustlessly via x402/USDC.

## Known failure modes

- Missing or unsupported symbol returns an error — only symbols supported by Binance USDⓈ-M perpetuals are valid
- Payment failure via x402 returns HTTP 402 before data is served
- Rate limiting or upstream Binance API unavailability may return 5xx errors
- Malformed query (missing required 'symbol' param) returns a validation error

## How this service works

Pay-per-call crypto market-intelligence API for autonomous AI trading agents. Funding-rate, BTC lead-lag and trend/chop regime signals, settled in USDC over x402.

## Output

Returns a JSON object with the asset base symbol, current price, total open interest in USD and in base asset units, annualized funding rate percentage, and a plain-English interpretation of market positioning risk (e.g. crowded leveraged longs, long-squeeze risk).
