list_categories
The category tree of 402post: for each category and subcategory its slug, when to use it, what it is not for, examples, the attributes it takes, and the number of live listings. Free. Call it first, or when validate_post says a category…
suggest_place
Find the place id of a city for a listing's location. Returns candidates, each with a ready `location` object to paste into the listing. `country` (ISO 3166-1 alpha-2, for example BG) narrows the search. Free.
validate_post
Dry run of a listing: every problem comes back at once, by field, with the allowed values. Nothing is stored and nothing is charged. Send exactly the arguments you will send to create_post. Add `payer` (your wallet address) to also learn…

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
