## 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 blockrun-tweet-replies-fetcher-2d2b7311
```

Example prompt: Can you pull all the replies to tweet ID 1812345678901234567 so I can see what people are saying about it?

## When to prefer this

Use this endpoint when you need to retrieve replies to a specific tweet programmatically and want payment handled on-chain in USDC without managing Twitter/X API credentials directly. It is especially well-suited for crypto/Web3-focused agents already operating within the BlockRun routing layer that need social data alongside DeFi data from the same provider.

## Known failure modes

- Invalid or non-existent tweet_id returns empty results or an error
- Tweet is from a private/protected account, resulting in no replies returned
- Rate limiting or payment failure returns a 402 or 429 status
- Deleted tweet returns an error or empty reply set
- Malformed tweet_id (non-numeric or wrong format) causes a 400 bad request

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

A list of reply tweets associated with the given tweet ID, likely including reply text, author identifiers, timestamps, and engagement metadata for each reply.
