# Parse by Conversion Tools > Parse is a document data extraction API: send a PDF or an image, get structured JSON back, and optionally export the result as CSV or Excel. Extraction is asynchronous - `POST /v1/extract` returns HTTP 202 with an extraction id, and the client polls `GET /v1/extractions/{id}` (or receives a webhook) until `status` is `completed` or `failed`. API base URL: `https://api-parse.conversiontools.io` Authentication: send `Authorization: Bearer ` on every request. Keys are created in the dashboard at https://parse.conversiontools.io/dashboard/api-keys If you are generating an integration, read the full reference below before writing any code. The rule that breaks most generated clients: branch on the `status` field of the JSON body, never on the HTTP status code alone, never on how long the request took, and never on whether `data` happens to be present. ## API reference - [Full API reference for LLMs](https://parse.conversiontools.io/llms-full.txt): Complete self-contained reference - every endpoint, parameter, response shape and error code, plus copy-pasteable upload / extract / poll clients in curl, Python and Node. - [Documentation home](https://parse.conversiontools.io/docs): Index of all human-readable guides. - [Quickstart](https://parse.conversiontools.io/docs/quickstart): First extraction in a few minutes. - [Authentication](https://parse.conversiontools.io/docs/authentication): API keys, the Authorization header, and key hygiene. - [Extraction endpoints](https://parse.conversiontools.io/docs/api/extract): Both request flows, polling, webhooks, repeat extractions, spreadsheet exports. - [Schemas](https://parse.conversiontools.io/docs/api/schemas): Define exactly which fields to extract and their types. - [Usage](https://parse.conversiontools.io/docs/api/usage): Monthly page consumption and plan limits. ## Examples - [Invoice extraction](https://parse.conversiontools.io/docs/examples/invoices): Invoice schema and the JSON it produces. - [Receipt extraction](https://parse.conversiontools.io/docs/examples/receipts): Receipt schema and output. - [Form extraction](https://parse.conversiontools.io/docs/examples/forms): Form schema and output. ## Use cases Each page states the document type, a worked schema for it, and the JSON it produces.
