# AgentFeed Funding Rate History

> AgentFeed Funding Rate History is a paid API for AI agents from x402.ochinimus.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Returns historical funding rate data for any USDT perpetual futures contract, including average rate, annualized percentage, positive-interval share, and the raw rate series over up to 200 intervals.

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 agentfeed-funding-rate-history-1cddbe66
```

Example prompt: What has the funding rate history actually been for SOLUSDT over the last 100 intervals — give me the average 8h rate, the annualized carry percentage, and how often the rate was positive.

## When to prefer this

Use this endpoint when you need historical, realized funding rate data for a specific USDT perpetual futures symbol — not a forecast, but what carry has actually occurred. Prefer this over live funding rate endpoints when analyzing trends, computing average carry, evaluating long/short bias over time, or building carry trade strategies. It covers any USDT perp symbol with configurable depth up to 200 intervals.

## Known failure modes

- Missing or invalid symbol returns an error — symbol must be a valid USDT perp format like SOLUSDT
- Limit out of range (below 1 or above 200) may return an error or default to 30
- Symbol with no recorded funding history may return an empty history array
- Payment failure (HTTP 402) if USDC payment via x402 protocol is not completed
- Upstream data source unavailability may result in stale or incomplete history

## How this service works

Funding rate history for any USDT perp, up to 200 intervals: the average rate, its annualized %, the share of intervals that were positive, and the raw series. Use when you need to answer: What has the carry on this perp actually been? What the carry has actually been.

## Output

Returns a JSON object containing the queried symbol, the number of intervals returned, the average 8-hour funding rate, the annualized funding rate percentage, the share of intervals that were positive, and the full raw time-series array of timestamped 8h rates.
