Sejda
Sejda provides online and desktop tools for editing and manipulating PDF documents - merge, split, compress, convert, edit, watermark, OCR, and fill forms. Its only documented hosted REST API is the HTML-to-PDF conversion API at api.sejda.com; the broader merge/split/OCR task set is delivered through the web and desktop apps and through the open-source Sejda SDK and sejda-console (Java, AGPLv3), not a hosted task API.
Sejda publishes 4 API contracts indexed on the APIs.io network, including HTML to PDF API, and 3 more. Tagged areas include PDF, Document Conversion, HTML to PDF, PDF Editing, and OCR.
The Sejda catalog on APIs.io includes 1 Spectral governance ruleset.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| RPA and Document AI (RPA marketplaces, intelligent document processing) | builds-on | 17.2 (thin) | - | - |
| PDF and Document Standards (PDF tooling, document signing trust, invoice documents) | builds-on | 17.2 (thin) | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 2
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
