```

Example prompt: Can you get me the details of tweet ID 20 along with a cryptographic signed proof that the content is authentic?

## When to prefer this

Use this endpoint when you need not just tweet content but a cryptographically signed attestation of that content — ideal for on-chain verification, legal evidence, or any use case requiring tamper-proof proof of a tweet's existence and content. Prefer over plain tweet-scraping endpoints when verifiability and provenance matter.

## Known failure modes

- Tweet not found or deleted — returns 404 or empty result
- Invalid tweet ID format — returns 400 validation error
- Rate limiting or payment failure — returns 402 payment required
- Twitter API unavailable — upstream service error 503
- Signing service failure — proof cannot be generated
