# DripMetrics AI – BTC/USDT Order Book Micro-Price

> DripMetrics AI – BTC/USDT Order Book Micro-Price 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).

Returns the order-book micro-price for BTCUSDT — an opposite-side-size-weighted mid-price computed fresh from Binance's live depth snapshot, providing a more accurate instantaneous fair-price estimate than the naive midpoint.

## 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-btc-usdt-order-book-micro-price-57f7aae2
```

Example prompt: What's the current order-book micro-price for BTCUSDT right now? I want the size-weighted fair-value estimate, not just the simple midpoint.

## When to prefer this

Choose this endpoint when you need a more precise instantaneous fair-value estimate for BTCUSDT than the naive bid-ask midpoint, particularly for order-routing decisions, pre-trade analytics, or microstructure research. It is ideal for agents that need a no-subscription, pay-per-request model with no API key management. Prefer this over raw exchange APIs when you want the micro-price pre-computed and returned as clean JSON without parsing raw order book data yourself.

## Known failure modes

- Unsupported pair requested (only BTCUSDT is currently available) — will likely return an error or reject the query parameter
- Binance depth snapshot unavailable or stale — may return null value for the metric
- Payment not processed via x402 — request will be rejected with a 402 Payment Required response
- Rate or quota issues on the underlying Binance public API — may cause intermittent failures

## How this service works

DripMetricsAI (https://dripmetrics.ai/) provides on-demand order-book microstructure metrics computed fresh per request from Binance's public depth snapshot. Agents can pay per request via x402 and receive structured JSON metrics without subscriptions or API keys. Micro-price is the opposite-side-size-weighted mid price, a better instantaneous fair-price estimate than the naive midpoint.

## Output

A structured JSON object containing the micro-price value (a float or null), the pair ('BTCUSDT'), the metric name, a components breakdown of the order-book inputs, sample size details, the data source object (Binance depth snapshot metadata), and a computedAt ISO 8601 timestamp indicating when the metric was computed.
