| Endpoint | Price | Returns |
|---|---|---|
| GET /x/digest | $0.02 | The one to use. Tweets plus an AI digest: 3–5 sentence trend summary, sentiment with the reason behind it, key themes, the accounts driving it, and the notable posts. Skips the second LLM call you'd otherwise make to summarize raw results yourself. |
| GET /x/search | $0.006 | Raw tweets only — up to 20 newest matches with author, follower count, timestamp, permalink and engagement. The cheap on-ramp when you want to do your own analysis. |
Both take ?query=<X advanced search>. Invalid queries return 400 before payment — you are never charged for a miss.
