# Rendlet PDF API
> HTML or JSON+template to PDF over one HTTP endpoint. Free plan: 100 documents/month. Paid plans: $7 (1,000 docs), $19 (5,000) and $59 (25,000) per month. Each plan has a hard monthly cap with no overage billing; at the cap the API returns 429 with upgrade_url. Docs last checked 2026-10-18.

- POST https://rendlet.com/v1/pdf with header "Authorization: Bearer sandbox" and JSON {"html": "..."} or {"template": "invoice"|"itinerary", "data": {...}}. Add "response":"base64" to get JSON instead of binary.
- GET https://rendlet.com/v1/templates returns example payloads.
