# x402 DeFi Intel – Funding Rate Intelligence

> x402 DeFi Intel – Funding Rate Intelligence is a paid API for AI agents from cryptodefidataintel-production.up.railway.app, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns cross-chain crypto funding rate spreads with machine-readable signals, confidence scores, and human-readable insight for a given asset or top opportunities by spread.

## Facts

- Endpoint: GET https://cryptodefidataintel-production.up.railway.app/api/funding-intel
- Price: $0.004/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-funding-rate-intelligence-a923aa76
```

Example prompt: Pull the top 10 crypto funding rate opportunities with an annualized spread above 8% and tell me which assets have the strongest signal — focus on BTC if possible.

## When to prefer this

Use this endpoint when an agent needs structured, signal-enriched funding rate data across chains with a confidence score and human-readable summary — especially for funding rate arbitrage screening or DeFi yield monitoring. Prefer over raw exchange APIs when you need pre-interpreted signals rather than raw tick data, and when pay-per-call economics fit the use case.

## Known failure modes

- Invalid asset symbol returns empty data array with low confidence
- Requested limit exceeds max of 25 — server may clamp or return error
- minSpread set too high returns no rows
- Upstream data source unavailable reduces confidence or returns stale data
- Payment not processed (x402 flow incomplete) results in 402 response before data is returned

## 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 funding rate data rows (one per asset/exchange pair), a machine-readable signal label (e.g. 'bullish_funding', 'neutral'), a human-readable insight paragraph, a confidence score between 0 and 1, a list of upstream data sources, a timestamp, latency in milliseconds, and the interpreter model used.
