🤖 Using an AI assistant? Copy this link into ChatGPT / Claude / Cursor — it reads every endpoint and parameter instantly and tells you if this API fits your use case.

The primary pdf_extract_text endpoint returns per-page text, page count, character count, empty-page count and a scanned flag, and you can read metadata, merge, split, rotate, convert PDF to images and images to PDF. It is built for document pipelines and data extraction that need PDF operations without a desktop tool. One ReefAPI key, one shared credit pool, the standard envelope.

Use cases

Who uses this API and why

Data pipelines call pdf_extract_text to turn PDFs into searchable or RAG-ready text.
Document tools use pdf_merge and pdf_split to assemble files.
OCR triage uses the scanned flag to route image-only PDFs correctly.

FAQ

Questions developers ask before integrating

What is the File Conversion API API?

File Conversion API API is a ReefAPI endpoint group for file conversion api It returns live JSON through POST requests under /file-convert/v1.

Is the File Conversion API API free to try?

Yes. ReefAPI starts with 1,000 free credits, no card required. File Conversion API calls use the same shared credit balance as every other ReefAPI engine.

Do I need a File Conversion API login or account?

No login to File Conversion API is needed for the API response. You call ReefAPI with your x-api-key header, and the playground can run live examples before you create a production key.

How fresh is the File Conversion API data?

The page example is captured from a live pdf_extract_text call, and production requests fetch live data through ReefAPI rather than a static sample.

How many credits does the File Conversion API API use?

File Conversion API actions currently cost 1-4 credits per successful call. Failed or blocked calls are free, and all APIs draw from one credit pool.

Can I call File Conversion API from an AI assistant or MCP client?

Yes. Connect ReefAPI once through MCP and your assistant can call file-convert actions with the same key, credit pool and JSON envelope used by normal REST requests.

Is the File Conversion API API a File Conversion API scraper?

It is the managed alternative to a DIY File Conversion API scraper. Instead of building and maintaining your own scraper — proxies, headless browsers, captcha and constant breakage — you call one ReefAPI endpoint and get the same file conversion api back as clean JSON.

Why does my File Conversion API scraper keep getting blocked?

Most File Conversion API scrapers break on anti-bot defenses, rate limits and IP bans that need rotating residential proxies and browser fingerprinting to clear. ReefAPI handles all of that for you — no proxies, no captchas, no maintenance — and returns live JSON. Blocked or failed calls are free.

base /file-convert/v131 endpoints

post/file-convert/v1/pdf_extract_text1 credit

Extract text from a PDF (per page). mode=layout preserves visual alignment (pdfplumber); mode=plain is fastest. Flags likely-scanned PDFs.

Parameter		Allowed / range	Description
file_b64	optional	—	The input file as base64 (data-URI prefix tolerated). Max 25MB. Provide file_b64 OR file_url. Multipart upload also works: POST the file as the 'file' form field.
file_url	optional	—	https URL of the input file — fetched server-side through the proxy pool; private/internal/metadata addresses are SSRF-blocked. Max 25MB.
filename	optional	—	Optional original filename — used only as a hint (e.g. .md detection); the real format is always sniffed from magic bytes.
password	optional	—	Password for encrypted PDFs. Without it an encrypted input fails cleanly with INVALID_PARAM (we never crack/bypass).
pages	optional	—	Page selection, 1-based: '1-3,5,9-' (open ranges OK). Default: all pages.
mode = plain	optional	plain · layout	plain = reading-order text; layout = whitespace-aligned text (tables stay readable).
