## 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-x-user-social-signal-daily-time-series-2322f022
```

Example prompt: Pull the daily social signal history for X user ID '12345678' on Messari from January 1, 2025 to March 31, 2025 — I want to see how their mindshare, sentiment, and engagement scores trended each day over that period.

## When to prefer this

Choose this endpoint when you need historical daily-granularity social signal trends for a specific X user in the crypto space — particularly for charting mindshare, sentiment, and engagement over time. Use the sibling hourly endpoint for finer resolution, or the asset-focused endpoint for crypto asset social signals rather than user signals. Best for longitudinal influencer analysis or detecting trend shifts day by day.

## Known failure modes

- Missing required 'granularity' parameter (must be '1d') returns a 400 validation error
- Invalid or unrecognized xUserID returns empty data array or 404
- Date range too broad or no data available for the period returns an empty array
- Payment not provided or insufficient USDC balance returns a 402 Payment Required
- Malformed date strings in start/end fields return a 400 parse error
