Two calls. Zero ceremony.

Multipart in, document out. Every error is application/problem+json with a stable machine-readable code, no parsing prose.

# Fill a PDF form from JSON
curl https://api.pagesmith.eu/api/v1/fill \
  -H "Authorization: Bearer psk_live_…" \
  -F file=@contract.pdf \
  -F 'data={"name":"Jesper","subscribed":true}' -o filled.pdf

# Validate for archival: rule-level PDF/A verdicts
curl https://api.pagesmith.eu/api/v1/pdfa/validate \
  -H "Authorization: Bearer psk_live_…" -F file=@archive.pdf
→ {"compliant": false, "failedRules": 1, "ruleSummaries": [{"ruleId": "6.3.1-1", …}]}

Subject to GDPR. Not the CLOUD Act.

US-owned processors answer to US law wherever their servers sit. pagesmith runs its own open-source engines on EU infrastructure. There is no American company, upstream API, or third-party processor in the path of your documents.

  • EU servers, EU company

    Processing happens in the European Union, under European jurisdiction, end to end.

  • Zero retention by architecture

    Documents live in memory for the duration of the request. No document bytes or filenames ever touch a database or disk store.

  • Our own engines

    pdfcpu, veraPDF and friends run on our hardware. No document is ever forwarded to anyone.

Honest pricing, metered in units

Every plan includes every operation. Fill, validate, merge and stamp = 1 unit; convert and seal = 3 units. From €29/month for 30 units, a fraction of what US incumbents charge per operation.
