## 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-api-daily-crypto-asset-social-signal-history-e35effeb
```

Example prompt: Pull the daily social signal history for Ethereum from Messari for the past 30 days — I want to see the mindshare, momentum score, and sentiment score at the 1d granularity.

## When to prefer this

Use this endpoint when you need daily-granularity historical social signal data for a crypto asset — specifically mindshare, sentiment, and momentum over a date range. Prefer this over the hourly endpoint when trend analysis over days, weeks, or months is the goal rather than intraday monitoring.

## Known failure modes

- Invalid or missing granularity parameter returns a 400 error
- Unknown assetID returns an empty dataset or 404
- Start/end date out of available historical range returns empty data
- Payment not fulfilled returns 402 Payment Required
- Rate limit exceeded returns 429 Too Many Requests

## How this service works
