## 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 api-dripmetrics-ai-13eaca65 -d '<json body>'
```

Example prompt: What's the wallet novelty score for the Polymarket market with slug 'will-the-fed-cut-rates-in-july' over the last 120 minutes? I want to know how much of the recent flow is coming from wallets that haven't been seen trading this market before.

## When to prefer this

Use this endpoint when you need to assess whether recent Polymarket market flow is driven by new, previously unseen wallets — a signal of organic interest, potential manipulation, or information leakage. Prefer this over general volume metrics when wallet diversity and novelty are the key diagnostic. Ideal for agents monitoring prediction market integrity or building risk-adjusted trading signals on Polymarket.

## Known failure modes

- Missing both conditionId and slug returns a 400 validation error
- Unknown or invalid conditionId/slug returns a 404 or empty result
- Insufficient trade data for the window returns a low-confidence or null metric
- Payment not provided or insufficient USDC results in HTTP 402 payment required
- Rate limiting or upstream Polymarket data unavailability causes 5xx errors
- Ambiguous multi-market event slug without conditionId may return wrong market data

## 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 structured JSON object containing the wallet novelty metric value (fraction of flow from new wallets), the analysis window, sample size (number of trades evaluated), component breakdown, the market slug or conditionId, data source, and a computed-at timestamp.
