## 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 bykaranteli-funding-rate-history-aa7430e3
```

Example prompt: Pull the settled funding rate history for BTCUSDT on Binance from January 1 2024 to March 31 2024, up to 500 rows, so I can compute the annualized carry for that period.

## When to prefer this

Choose this endpoint when you need historical settled funding rates for perpetual futures across major crypto exchanges, specifically for carry analysis, basis trading backtesting, or cross-venue funding comparisons. It is distinct from live funding rate feeds or liquidation data endpoints.

## Known failure modes

- Invalid symbol or exchange name returns empty rows array
- Date range too large may be capped at dataset row limit
- Missing required query parameters may return error or empty result
- Unsupported currency filter returns no matching rows
- Payment failure (402) if x402 micropayment is not attached

## How this service works

Settled funding rate history at per-venue, per-settlement granularity (every 8h print with its source exchange), the series behind carry and basis work. The free CC0 metric-daily download already carries a single daily BTC funding aggregate; this route is for the venue-level record.

## Output

Returns a JSON object with ok=true, a dataset label of 'funding-history', a count of returned rows, and a rows array containing settled funding rate records per symbol and venue — each record includes timestamp, symbol, exchange, and funding rate value.
