DataXAPI

Find which capability returns the data you need, when its ID is not obvious from the `call` list. Say the need in plain words, English or Chinese. Returns up to 5, each with its required parameters, price and a ready-made call. Free, no key. When nothing matches on a named platform it lists everything that platform has: pick from it, or tell the user it is not there. Never use another platform's capability instead.

The whole contract of 1 to 5 capabilities: parameters, fields returned in each view, paging, price and the most one call can cost, what it cannot give, example calls. Free, no key. Use it before `call` when unsure of the parameters.

Fetch one page of data from one capability. Charged per call or per item, as `describe` says; an error costs nothing. IDs read platform.resource.action; give only the parameters that capability takes. The first line of the result says how many items, the charge, the balance, and how to get the next page (`cursor`: a new charged call) or the rest of a result cut to about 20 KB (`read_more`: free). Needs an API key.

Read the rest of a result that `call` cut to fit, or the same result in another view. Free: nothing is fetched again; results are kept 24 hours. Needs the API key that made the call.

balance: the balance, this key's budget and spending. receipt: what one call was charged, by its result ID. usage: calls and charges by day or capability. status: which capabilities are up (no key). Free.
