## 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-crypto-asset-daily-metric-time-series-835a379d
```

Example prompt: Pull the daily price_usd history for bitcoin from Messari from January 1 2023 to December 31 2023 so I can run a backtest.

## When to prefer this

Use this endpoint when you need daily-resolution historical metric data for a crypto asset — ideal for backtesting strategies, building agent memory, or trend analysis over weeks/months/years. Choose the sibling 1h or 5m endpoints when you need intraday granularity.

## Known failure modes

- Invalid asset identifier returns 404 or empty data
- Unknown metric dataset slug returns error or no results
- Date range outside available history returns empty array
- Malformed date format returns 400 bad request
- Missing required fields (entityIdentifier or datasetSlug) returns 400
- Insufficient payment / x402 payment failure blocks response
- Rate limit exceeded returns 429

## How this service works

Get daily cryptocurrency asset metric history for backtests and agent memory.

## Output

An array of timestamped metric value objects (timestamp + value pairs) at daily granularity for the requested asset and metric slug, covering the specified date range.
