## 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 mesh-heurist-xyz-7f2e8533 -d '<json body>'
```

Example prompt: Pull the last 20 smart mentions for the Twitter account 'VitalikButerin' from the past week so I can see who's been engaging with them.

## When to prefer this

Use this endpoint when you need to retrieve and analyze recent Twitter mentions for a specific account, especially in a crypto/Web3 context where smart filtering helps surface signal over noise. Prefer this over raw Twitter search when you want pre-filtered, relevance-scored mentions rather than raw firehose results.

## Known failure modes

- Username not found or invalid — returns empty or error response
- Date range yields no mentions — returns empty feed
- Rate limiting or quota exceeded — payment/access error
- Invalid Unix timestamps for fromDate/toDate — returns validation error
- Network or upstream Twitter API failure — service unavailable error
