# Crypto Funding Rates Oracle

> Crypto Funding Rates Oracle is a paid API for AI agents from home.chrz.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

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 crypto-funding-rates-oracle-6abf48f7 -d '<json body>'
```

Example prompt: Pull the current top perpetual futures funding rate opportunities right now — I want to see which symbols have the highest APR, which exchange they're on, and when the next funding event hits.

## When to prefer this

Choose this endpoint when an AI agent needs real-time perpetual futures funding rate data sorted by opportunity (APR), especially for cross-exchange scanning. It is specifically optimized for agent-native x402 micropayment flows on Solana mainnet, making it ideal for autonomous trading agents that need to pay per-call without API key management. Prefer it over free alternatives when you need curated, ranked opportunity data rather than raw feed data.

## Known failure modes

- Payment not included or invalid x402 Solana payment header — returns 402 Payment Required
- Insufficient USDC balance on agent wallet — payment fails before data is returned
- Exchange data temporarily unavailable — ok may be false or opportunities array may be empty
- Rate limiting if called too frequently without valid payment
- Network timeout on Solana mainnet payment confirmation

## How this service works

## Output

A JSON object with ok status, a checked_at timestamp, and an array of opportunities each containing: symbol (e.g. 1000RATSUSDT), exchange (e.g. bybit), funding_rate (e.g. 0.001), interval_hours (e.g. 8), apr (e.g. 109.5), and next_funding_time (ISO timestamp).
