X-Twitter/API
from HTYP, the free directory anyone can edit if they can prove to me that they're not a spambot
Twitter has multiple levels of API, ranging from public (no special authorization needed) to Enterprise (your market cap must be at least this high to use).
From most to least accessible:
- Public:
- Twitter for Websites
- Replay API (I think this is public)
- Developer
- Premium
- Enterprise
