# PDF scraper API

A PDF scraper API that works on a whole website instead of one file: you pass a domain and get back every PDF, Word, Excel and CSV document it publishes, each one already converted to structured Markdown with its headings, tables, lists and links intact. One row per document, with title, author, page count and word count — billed per document delivered.

$0.005 per delivered document · $2 free every month · Failed runs never billed

POST /v1/scraper/collectors/site_documents/run

```
$ curl $QD/site_documents/run \
    -H "Authorization: Bearer $QD_API_KEY" \
    -d '{"domain": "bitcoin.org", "doc_types": ["pdf"], "max_results": 5}'
{ "status": "done", "count": 5,
  "results": [
    {
      "url": "…",
      "source": "…",
      "kind": "…",
      "title": "…" } ],
  "cost": 0.025 }
# 5 documents × $0.005 · nothing delivered, nothing charged
```

You send domain and doc_types; the run goes out through a residential exit and comes back as documents with source, kind and title — 11 fields on every row — and you are billed $0.005 for each document actually delivered, nothing for a run that delivers none.

**$0.005 / document**400 documents on the free $2 every month

**Semantic input**domain, doc_types, max_chars_per_doc — no URL lists

**Up to 50**documents per run, pagination handled for you

**No browser**read over HTTP/TLS — cheaper and faster than rendering

## What a PDF scraper API does

Scraping PDFs from a site is two problems wearing one name. The first is finding them: the whitepaper is linked from the homepage, the annual report only from the sitemap, and the ones that matter are never in the same place twice. The second is reading them: `pdf-parse` and friends hand you a flat dump where a two-column paper interleaves its columns, a table becomes a smear of numbers and the running header repeats on every page. This collector does both — link discovery on the homepage first, then the sitemap only if it still needs documents, and a layout-aware conversion built on positioned text runs rather than a flat dump.

The converter is the part you would not want to write. Headings come from clustering the real font sizes, cross-checked against the PDF outline when the file has one; bold, italic and monospace come from the font names; tables are rebuilt as GFM only where columns actually line up, which is what keeps justified paragraphs out; two-column pages are split on the gutter and read column by column; recurring headers, footers and page numbers are dropped; hyphenated line breaks are repaired and paragraphs rejoined across pages; and link annotations are remapped onto the text they covered. What lands in your pipeline is Markdown a model can read, not a wall of characters. Only documents hosted on the domain you asked for are fetched — a harvest of `acme.com` never wanders off to a third-party CDN.

Input is meaning, not a URL *domain* *doc_types* *max_chars_per_doc* *country* *max_results*

## What one document looks like

Every delivered document carries these fields. Nullable means the source did not publish it — the field stays empty instead of being guessed.

| Field | Type | What it holds |
| --- | --- | --- |
| `url` | string | Document URL. |
| `source` | string | Where the link was found: page \| sitemap. |
| `kind` | string | pdf \| docx \| xlsx \| csv. |
| `title` | string · nullable | Document title (PDF metadata or first heading). |
| `markdown` | string | The document converted to Markdown (headings, tables, lists, links). |
| `chars` | integer | Markdown length in characters. |
| `words` | integer | Word count of the Markdown. |
| `pages` | integer · nullable | Page count (PDF only). |
| `author` | string · nullable | Author from document metadata, when present. |
| `scanned_pages` | integer | Image-only pages with no text layer (no OCR applied). |
| `truncated` | boolean | True when the content hit max_chars_per_doc or the page cap. |

## Inputs

The whole request. Anything you leave out falls back to the default shown in the catalog.

| Input | Type | Required | What it does |
| --- | --- | --- | --- |
| `domain` | string | yes | Domain or site URL to harvest documents from. |
| `doc_types` | array | no | Which document types to collect (default pdf + docx). |
| `max_chars_per_doc` | integer | no | Cap on the Markdown returned per document (1,000–200,000). |
| `country` | string | no | ISO 3166-1 alpha-2 code — proxy exit geo and Google locale (gl). Omit for the default pool. |
| `max_results` | integer | no | How many documents to deliver at most (1–50). You pay only for delivered documents. |

Integration

## One POST, typed rows

Base URL `https://api.quanticdata.io/v1`, Bearer auth, the same key as every other Data API. Endpoint: `POST /v1/scraper/collectors/site_documents/run`.

```
curl -X POST https://api.quanticdata.io/v1/scraper/collectors/site_documents/run \
  -H "Authorization: Bearer $QD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain":"bitcoin.org","doc_types":["pdf"],"max_results":5}'
```

```
import requests

r = requests.post(

    headers={"Authorization": f"Bearer {QD_API_KEY}"},
    json={
        "domain": "bitcoin.org",
        "doc_types": [
            "pdf"
        ],
        "max_results": 5
    },
    timeout=120,

## What people build with the PDF scraper API

Three shapes of work this endpoint was designed around.

### RAG ingestion

Point it at a regulator, a vendor or your own site and the corpus arrives as Markdown with headings preserved, which is exactly the structure a chunker needs to split on. Set `pdf.pageMarkers`-style limits with `max_chars_per_doc` and each row stays inside your context budget.

### Due diligence and research

Every whitepaper, prospectus, price list and datasheet a company publishes, in one call — with the source URL on each row so a quote can always be traced back to the document it came from.

### Document monitoring

Re-run on a schedule and diff by URL: new filings and updated brochures show up as new or changed rows, without a crawler to maintain.

## PDF scraper API versus rolling your own

The differences that actually cost time when you build this in-house.

|  | DIY scraper | This collector |
| --- | --- | --- |
| Finding the documents | Your own crawler, plus a sitemap parser | Homepage links first, sitemap only if more are needed |
| Reading a PDF | Flat text dump — columns interleaved, tables destroyed | Layout-aware Markdown: headings, GFM tables, lists, links |
| Scope | Whatever your crawler wanders into | Same-site only, on the registrable domain you asked for |

## What people search for

The same call you would paste into a terminal: a Bearer key, domain, doc_types and max_chars_per_doc in the body, and back the envelope every QuanticData endpoint returns — type, message, payload — where count is how many documents arrived and usage.cost_usd is $0.025, which is 5 × $0.005. A run that delivers nothing costs nothing. The key is good for 60 req/min on the free tier.

## FAQ

Questions we get about the PDF scraper API.

[Something else? Ask us →](mailto:hello@quanticdata.io)

### Which document types does it collect?

PDF and DOCX by default; XLSX and CSV are available through `doc_types`. PDFs go through the layout-aware engine, Word files keep their formatting, and spreadsheets come back as Markdown tables.

### What happens with scanned PDFs?

They are delivered like any other document, and the row tells you the truth about them: `scanned_pages` counts the image-only pages with no text layer. No OCR is applied and none is faked — a scan comes back with the text it actually contains, and you decide whether to send it to an OCR step.

### How long can one document be?

As long as you allow: `max_chars_per_doc` runs from 1,000 to 200,000 characters and defaults to 40,000. When a document is cut at that limit the row carries `truncated: true`, so a shortened conversion is never mistaken for a short document.

### Does it fetch documents hosted somewhere else?

No. Discovery is fenced to the registrable domain you passed, so links pointing at a third-party host are skipped rather than fetched. That keeps the bill, and the legal surface, on the site you actually asked about.

### Is there a free PDF scraper API?

Every account gets $2 of credit every month with no card, which is about 400 delivered documents on this endpoint at $0.005 each. It renews monthly, and a run that delivers nothing is never billed — so a failed or blocked attempt does not eat the allowance.

### How much does one run cost?

Multiply the rows you actually receive by $0.005. A run capped at 50 documents — the maximum for this collector — costs $0.25 if every row comes back, and less when the source has fewer. Volume tiers take up to 30% off, and `GET /v1/scraper/collectors` returns the price your key actually pays.

## Run the PDF scraper API now
