## Tools (3)

- `convert_document`: Convert a document up to 8 MB to Markdown and return it directly.

Pass the file as base64 in `content_base64`, or as a download link in
`file`, and its name in `filename`. The extension decides the type: .pdf,
.docx, .pptx, .xlsx, .html, .htm or .txt. Returns `markdown` and `meta`
(`filename`, `length` in characters). PDFs come back as plain text
without headings and without OCR. For scans, tables and page numbers,
use `submit_conversion_job`. Works without an API key at the anonymous
rate limit.

Credits: 1 per call.
- `get_conversion_job`: Check a queued conversion job you submitted.

Returns `job_id` and `status` (`queued`, `running`, `succeeded` or
`failed`). A succeeded job includes the `markdown` when it is under
100 KB, otherwise a `result_url` to download it (also free). A failed job
includes `error`, one sentence with the reason. Results are deleted
7 days after submission. An expired result is reported in `error`.
Requires an API key.

Credits: free. This tool is not metered.
- `submit_conversion_job`: Queue a document up to 25 MB and 200 pages for conversion with OCR and tables.

Pass the file as base64 in `content_base64`, or as a download link in
`file`, and its name in `filename` (.pdf, .docx, .pptx, .xlsx, .html,
.htm or .txt). Returns `job_id`, `status` and `result_url`. Call
`get_conversion_job` with the `job_id` until `status` is `succeeded` or
`failed`. A conversion may take up to about 2 minutes.

Optional `webhook_url`: a public http or https URL that receives a POST
with the job's final state. The request carries
`X-Appkit-Signature: sha256=<hex>`, an HMAC-SHA256 of the raw body keyed
with the returned `webhook_secret` (shown only once). 3 delivery attempts.

Requires an API key. The credits are refunded if the job fails. The
uploaded file is deleted when the job finishes. Results are kept for
7 days after submission.

Credits: 10 per call.
