Write a question
Each question needs anid, a type, a version, and instructions. Write
the instructions as you would brief a careful reader.

400 invalid_input with the name to fix.
Classify topics
A topic classifier is 1choice question whose categories are your topics.
Add other for posts outside them. analysisSummary.questions.<id>.shares
holds each topic’s share of posts.
Version your questions
version is yours. Change it whenever you change a question’s instructions,
categories, or levels. Each answer carries questionVersion, so stored rows
show which wording produced them.
Use a preset
Setanalysis.preset instead of questions for a ready set, at the same
price.
Pick the posts to analyze
SendtweetIds, texts, or a search, never more than 1. Sending none, or more
than 1, returns 400 invalid_input.
A search combines every search field you send into 1 X search.
queryType sets the order, Latest or Top. For more posts than 1 call
returns, send the same search again with cursor set to next_cursor. Stop
when has_next_page is false.
Compare with an earlier answer
Send theresults of an earlier call as baseline to see what changed. Each
row in the new results gets monitor, and analysisSummary.monitor counts
the posts per status. The comparison costs nothing extra.
id, or tweet.id, and its answers. Send
whole result rows when you have them. Their monitor carries the settings’
fingerprint, so rows from other settings show as not_comparable.
A decision counts as changed only when the new answer clearly leaves the old
one, so near ties between calls stay
unchanged. Keep analysis the same
between calls for comparable answers.
Budget the analysis
Each analyzed post costs 2 credits. Each text intexts costs the same. Posts
in unanalyzed cost nothing.
When credits cover fewer posts than you asked for, fewer come back. The posts
left over appear in unanalyzed with insufficient_credits. If credits cover
no post, the call returns 402 insufficient_credits.

Yes.results[].analysis.answers gives each answer’s confidence and the
probability of every category or level. Keep the rows above your threshold.
