## 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 witness-bnbot-ai-791584fd -d '<json body>'
```

Example prompt: Can you fetch the details of tweet ID 2035906492797456568 and get me a signed cryptographic proof that the content is real and hasn't been tampered with?

## When to prefer this

Use this endpoint when you need not just tweet content but also a cryptographic proof of its authenticity — ideal for legal evidence, fact-checking workflows, archival purposes, or any use case requiring tamper-evident records of tweet data. Prefer this over simple tweet lookup APIs when verifiability and non-repudiation matter.

## Known failure modes

- Tweet ID not found or deleted — returns 404 or error response
- Invalid tweet ID format — returns validation error
- Payment not provided or insufficient — returns 402 Payment Required
- Tweet is from a private/protected account — access denied
- Signing service unavailable — returns 503
