# XML to JSON Converter
> Convert XML to JSON. Element names become object keys, attributes get a configurable prefix (@, _, or none), text content gets a configurable key name, and repeated sibling elements become a JSON array automatically — with an option to force every element into an array so the shape never depends on how many times it repeats. Runs entirely in your browser.

title: iotools.cloud API
version: 1.0.0
description: >-
Run any iotools.cloud tool over HTTP.
Authenticate with `Authorization: Bearer iot_live_…`.
**Only `POST /v1/tool/{slug}` costs credits.** Every GET here — the catalog,
a tool's schema, your balance — is free. A tool call is charged its own
weight or your plan's per-call minimum, whichever is larger;
`x-iotools-credit-cost` on each operation is quoted at the free-tier
minimum, and `GET /v1/tools/list` returns the exact figure for your key.
`GET /v1/me/credits` reports what you have left, and `GET /v1/me/usage`
reports what it went on.
Failures are RFC 9457 problem documents — branch on `code`.
