## 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 palmyr-twitter-post-c4758b4b -d '<json body>'
```

Example prompt: Post this tweet to my Twitter account: 'Just shipped a new feature — AI agents can now pay with USDC and tweet autonomously. The future is here. #AI #Web3'

## When to prefer this

Use this endpoint when an AI agent needs to autonomously post content to Twitter/X and can pay per-call in USDC via the x402 protocol. Ideal for agents on Solana or Base that need to publish social updates without managing OAuth flows directly — the companion /social/twitter/login endpoint handles authentication. Prefer this over direct Twitter API integration when operating in an agent-native, micropayment-based infrastructure context.

## Known failure modes

- Not authenticated — requires prior login via POST /social/twitter/login
- Payment failure — insufficient USDC balance for the $0.001 per-call fee
- Tweet content exceeds 280 character limit
- Duplicate tweet rejected by Twitter API
- Twitter API rate limit exceeded
- Invalid or expired session token
- Network timeout reaching Twitter API
