Extract a inspection report PDF to JSON
Everything below is the response the live API returned for a inspection report, generated when this page was built. Not a description of what it would return — the output itself, including what it scored low on.
Who this is for
Compliance, facilities and asset-management tools keeping an auditable record of periodic inspections.
The job, in the words people search for: “digitise inspection reports into a compliance record”.
What makes this shape awkward
A pass/fail column of single characters beside a long observations column. Short cells and very long cells in the same table pull the column bands in opposite directions, and an observation that wraps onto a second line is the commonest cause of a table ending early.
The measured result
| Pages read | 1 |
| Time | 7 ms (7 ms/page) |
| Labelled fields found unprompted | 5 |
| Tables | 1 (8 rows) |
| Input | inspection-report.pdf (29 KB — synthetic, generated from a spec in the repo; real documents of this type cannot be published) |
Fields, with a schema
Ask for the fields you want by the label printed on the page. Each answer carries the text exactly as printed (raw), the value coerced to the type you asked for, a confidence, and a bounding box you can draw on the page to check it.

}'What came back
| Field | raw | value | confidence |
|---|---|---|---|
report_number | INS-2026-2214 | "INS-2026-2214" | 60% |
inspection_date | 2026-03-12 | "2026-03-12" | 70% |
next_due | 2026-09-12 | "2026-09-12" | 70% |
Every label it found without being asked
Send no schema and you get all of these, keyed by the label as printed. Useful for discovering what a new supplier’s layout actually contains before you write a schema against it.

Tables
Ref · Item · Result · Observation · 8 rows × 4 columns · page 1
Table confidence 90%. Header confidence 100% — the first row was promoted out of the data.
| Ref | Item | Result | Observation |
|---|---|---|---|
| 1 | Fire alarm panel | Pass | No faults logged |
| 2 | Emergency lighting | Pass | All units tested |
| 3 | Extinguishers | Fail | Unit 3B overdue service |
First 3 of 8 rows.
With options.rows_as_objects, the same row keyed by its header:
{
"Ref": "1",
"Item": "Fire alarm panel",
"Result": "Pass",
"Observation": "No faults logged"
}What this does not do
- No OCR. This reads the PDF’s text layer. A scanned or photographed inspection report has no text layer and returns
422 extraction_failedwith the page numbers that were blank — deliberately, and quickly, so you can route it somewhere that does OCR rather than waiting on a guess. - No model. Run the same file twice and you get the same bytes back. That is the trade: it cannot infer a field that is not printed, and it cannot hallucinate one either.
- Ambiguity is reported, not resolved. A date like 03/04/2026 stays a string, and a bare
$returns a null currency, because guessing wrong on either is not something you can recover from downstream.
