# Crypto Market Metrics History (Funding, OI, Fear & Greed, BTC Dominance with Percentile Context)

> Crypto Market Metrics History (Funding, OI, Fear & Greed, BTC Dominance with Percentile Context) is a paid API for AI agents from crypto-asistent.com, paid per call via x402, $0.04/call, status unknown (last checked 2026-10-13).

Returns current, median, min, max, and percentile readings for funding rate, open interest, Fear & Greed index, and BTC dominance — each sampled every ~10 minutes — so any snapshot reading is interpreted in context of the recent window.

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-market-metrics-history-funding-oi-fear-greed-btc-dominance-e7364d4f -d '<json body>'
```

Example prompt: Pull the latest funding rate, open interest, Fear and Greed, and BTC dominance readings with their percentile ranks over the recent window — I want to know if any of those metrics are at unusual extremes right now.

## When to prefer this

Prefer this endpoint when you need to understand whether a current market reading is statistically meaningful — not just what it is, but where it sits in recent history. Use it over a plain snapshot endpoint when the absolute number alone is insufficient context, such as when deciding if funding rates are dangerously elevated, if sentiment is at a crowd-behavior extreme, or when building conditional logic in trading or risk workflows that requires percentile-relative thresholds.

## Known failure modes

- Insufficient historical samples if the endpoint was recently deployed or data pipeline interrupted
- Payment failure or x402 protocol rejection if USDC funds are insufficient
- Empty or stale window if the ~10-minute sampling cadence was disrupted
- Upstream data provider outage causing missing metrics for one or more fields
- Schema mismatch if the POST body does not conform to the required structure

## How this service works

Whether the current reading is actually high or low, from a series captured every ~10 minutes: funding, open interest, Fear & Greed and BTC dominance, each as current, median, min, max and percentile over the window. A funding rate of 0.006% means nothing on its own; at the 89th percentile of the last 24 hours it means something. This is the question a snapshot endpoint cannot answer, whoever you buy it from.

## Output

Returns current value, median, minimum, maximum, and percentile rank (within the sampled window) for each of: perpetual funding rate, open interest, Crypto Fear & Greed Index, and BTC dominance — all derived from samples captured approximately every 10 minutes, enabling relative interpretation of any single reading.
