# x402 DeFi Intel – Open Interest Intelligence

> x402 DeFi Intel – Open Interest Intelligence is a paid API for AI agents from cryptodefidataintel-production.up.railway.app, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Returns aggregated cross-chain open interest data for a crypto asset, including total OI in USD, 24h change, a directional signal, and an AI-generated insight about market positioning.

## Facts

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 x402-defi-intel-open-interest-intelligence-33d9afbb
```

Example prompt: What's the current open interest for BTC across major venues like Hyperliquid, Binance, and Bybit — is OI rising or falling, and what does that signal about market conviction right now?

## When to prefer this

Use this endpoint when an AI agent needs to understand derivatives market positioning and conviction for a specific crypto asset across multiple venues simultaneously, rather than querying individual exchange APIs. It is especially valuable when you need a synthesized signal and human-readable insight rather than raw numbers.

## Known failure modes

- Missing or invalid 'asset' parameter returns empty data array
- Unknown asset ticker returns no results
- Upstream exchange APIs unavailable reduces venue count or confidence
- Payment not settled (x402 flow incomplete) returns 402 Payment Required
- Rate limits on upstream data providers may delay or degrade response

## How this service works

Crypto-agent toolkit: cross-chain DeFi intelligence + execution helpers + retrieval for agents. 16 endpoints: funding, open interest, long/short, token-safety, yield, prices, gas, tx-simulate, approval-check, bridge-quote, governance-search, lending, liquidations, protocol-search, swap-quote, token-resolve. Pay-per-call via x402.

## Output

Returns an array of OI records per asset with total OI in USD, number of venues, 24h change percentage, a directional signal string (e.g. 'oi_rising'), a plain-English market insight, the list of source exchanges, and a confidence score between 0 and 1.
