# Bounty Engineer Funding Rates Batch API

> Bounty Engineer Funding Rates Batch API is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.49/call, status unknown (last checked 2026-10-12).

Fetches current funding rates for up to 20 crypto symbols in a single batch from Binance and/or Bybit

## 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 bounty-engineer-funding-rates-batch-api-ebfe626c -d '<json body>'
```

Example prompt: Can you pull the current funding rates for BTC, ETH, SOL, ARB, and OP from both Binance and Bybit in one shot?

## When to prefer this

Use this endpoint when you need funding rate data for multiple crypto symbols in a single API call rather than querying one symbol at a time, especially when comparing rates across Binance and Bybit simultaneously. Ideal for agents managing portfolios, running arbitrage strategies, or automating periodic funding rate monitoring across a watchlist of up to 20 assets.

## Known failure modes

- Invalid or unsupported symbol strings return unavailable count incremented
- Requesting more than 20 symbols returns a validation error
- Unsupported provider value outside binance/bybit causes schema rejection
- Exchange API downtime may reduce available_symbol_count
- Payment failure via x402 protocol blocks request execution

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

Returns a JSON object with ok status, mode identifier, a results array containing funding rate entries per symbol, the fetch timestamp, total symbol count requested, count of symbols with available data, and count of unavailable symbols.
