The Messages API and SDKs
Comes up in: AI engineering
This concept is being written. It gets the full five steps — explanation, predict, interview angle, practice with tests, and review cards. Here is exactly what it will cover, so you can study it elsewhere in the meantime.
What it covers
- request shape (system, messages, roles, content blocks)
- responses and stop reasons
- official SDKs vs raw HTTP
- multi-turn state is the client's job
- images and documents as input
- keeping keys server-side
Words you will know
What you will practise
- first call in TS and Python (mocked in CI, live optional)
Interview questions this answers
- How do you make LLM API calls reliable in production?
- Which errors should you retry and how?
- How do you stop an LLM feature from blowing your budget?
