# Post to X

Post through the OpenTweet REST API. The key is in the
OPENTWEET_API_KEY environment variable.

## Publish a tweet now

curl -X POST https://opentweet.io/api/v1/posts \
  -H "Authorization: Bearer $OPENTWEET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Tweet text here", "publish_now": true}'

## Schedule a tweet (ISO 8601, UTC)

curl -X POST https://opentweet.io/api/v1/posts \
  -H "Authorization: Bearer $OPENTWEET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Tweet text here", "scheduled_date": "2026-07-10T09:00:00Z"}'

## Rules

- Keep every tweet under 280 characters.
- Never send publish_now and scheduled_date in the same request.
- Show the drafted tweet to the user before posting it.
- If the API returns an error, report it. Do not retry blindly.
