# DataXAPI docs

207 endpoints on 21 platforms, from $0.0003 a call, take the same parameters and answer in one envelope. Learn it once in the 10 guides below, then look any endpoint up in the API reference.

## The guides

- [Quickstart](https://dataxapi.com/docs/quickstart.md): Get a key, make one call and read the answer. A new account can try it free with $0.10 of credit, and the same three steps work on all 21 platforms.
- [Authentication](https://dataxapi.com/docs/authentication.md): How a call is authenticated: one Authorization header with your key. An account holds up to 50 keys, each with a spending limit, an expiry and a scope; a key is shown once, when it is made.
- [Requests and responses](https://dataxapi.com/docs/requests.md): One path per endpoint under /v1, the same parameter names on all 207 endpoints, and one envelope for every answer: code, request_id, data, page, warnings, meta.
- [Pagination](https://dataxapi.com/docs/pagination.md): One call returns 1 page. Pass page.next_cursor back as cursor for the next one; each page is charged as a call of its own, and a cursor says when it expires.
- [Billing](https://dataxapi.com/docs/billing.md): What a call costs ($0.0003 to $0.0400), when it is charged and when it is not, how an Idempotency-Key keeps a retry from being charged twice, and how the prepaid balance works.
- [Errors](https://dataxapi.com/docs/errors.md): All 34 error codes of the API on one page, each with its HTTP status, what it means, what to do, whether you were charged and whether to retry.
- [Rate limits](https://dataxapi.com/docs/rate-limits.md): Every answer carries 3 rate-limit headers that say the limit, what is left and when it resets. A request over the limit gets 429 at once, is not charged, and says how long to wait.
- [SDKs](https://dataxapi.com/docs/sdk.md): The TypeScript and Python SDKs: 207 typed methods, an idempotency key on every call, retries as the service allows, paging with limits on items and spend, and one role across platforms.
- [Command line](https://dataxapi.com/docs/cli.md): The dataxapi command line: 8 commands to find an endpoint, see its price, call it, read on, check the balance, run a task and set up your agents. Exit codes 0 to 5 tell a script what to do next.
- [MCP server](https://dataxapi.com/docs/mcp.md): One remote MCP endpoint with 5 tools gives an agent all 207 endpoints: the address, the entry for Claude Code, Codex and Cursor, what each tool does and what it costs.
