# DripMetrics AI Beta Metrics Endpoint

> DripMetrics AI Beta Metrics Endpoint is a paid API for AI agents from api.dripmetrics.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

## 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 dripmetrics-ai-beta-metrics-endpoint-f5ef0cb2
```

Example prompt: What's the current beta metric for ETH-USD on Coinbase over the last 30 minutes?

## When to prefer this

Choose this endpoint when you need on-demand, real-time market microstructure metrics (such as beta) for specific crypto trading pairs on Binance or Coinbase, especially for quantitative trading workflows, risk dashboards, or agent-driven analytics that require structured coverage metadata alongside the metric value. Prefer this over raw exchange APIs when you want pre-computed microstructure analytics with coverage guarantees rather than raw trade data.

## Known failure modes

- Unsupported pair/exchange combination returns an error or empty result
- 2h and 3h windows only supported for BTCUSDT/BTC-USD — using other pairs with these windows may fail
- Partial data flag set to true if insufficient trades exist in the window
- Coverage ratio below 1 indicates incomplete data for the requested window
- Payment not completed or x402 auth missing causes 402 payment required response
- Rate limiting or downstream exchange API errors may cause transient failures

## How this service works

DripMetricsAI (https://dripmetrics.ai/) provides on-demand crypto market microstructure metrics, Hyperliquid candle metrics, Polymarket diagnostics, and on-chain DefiLlama metrics for agents, dashboards, and trading workflows.

## Output

A JSON object containing the computed metric name (e.g. 'beta'), the trading pair, exchange, lookback window, computed numeric value, timestamp of computation, trade count used, first and last trade times, and a coverage object indicating whether the full window was available (coverage ratio, partial data flag, effective vs requested window minutes, error message if any).
