## 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 messari-asset-metrics-15-minute-time-series-2b49f3fc
```

Example prompt: Pull the last 6 hours of Bitcoin price_usd data from Messari at 15-minute intervals, starting from 2025-06-01T00:00:00Z to 2025-06-01T06:00:00Z.

## When to prefer this

Use this endpoint when you need sub-hourly, short-horizon cryptocurrency asset metric data at 15-minute resolution — ideal for intraday trading signals, short-term pattern detection, or monitoring recent asset behavior. Prefer this over the 1h or 1d endpoints when you need finer granularity without the full overhead of 5-minute data. Choose over the blockchain network metrics sibling when the subject is a specific crypto asset (e.g., bitcoin, ethereum) rather than a chain-level network metric.

## Known failure modes

- Invalid entityIdentifier (unknown asset slug) returns 404 or empty data
- Invalid datasetSlug (unsupported metric) returns error or no results
- Start/end time outside available data range returns empty array
- Malformed ISO-8601 date strings cause 400 bad request
- Payment not included or insufficient (x402 payment required) returns 402
- Rate limiting or quota exceeded returns 429

## How this service works

Get 15-minute cryptocurrency asset metric history for short-horizon signals.

## Output

An array of timestamped metric values at 15-minute intervals for the specified asset and metric slug, returned as [{timestamp, value}] objects covering the requested time window.
