Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-stablecoin-daily-metric-time-series-9dd509d9
```

Example prompt: Pull the daily circulating supply history for USDC (usd-coin) from Messari from January 1 2024 to June 30 2024 — use the circulating-supply dataset slug and default daily granularity.

## When to prefer this

Use this endpoint when you need daily-granularity historical trend data for a specific stablecoin metric over a custom date range. Prefer this over the 5-minute or 15-minute sibling endpoints when high-frequency intraday data is not required and you want cost-efficient lookups for trend analysis or agent memory. Choose over the explicit 1d route sibling only when the default daily granularity is acceptable.

## Known failure modes

- Invalid entityIdentifier returns 404 or empty data
- Unknown datasetSlug returns error or no results
- Date range with no available data returns empty array
- Malformed ISO-8601 date strings cause 400 bad request
- Payment failure (x402) blocks access if USDC balance is insufficient

## How this service works
