Sensible

Sensible is a developer-focused document understanding platform that converts unstructured documents (PDFs, emails, images) into JSON. The core IP is SenseML — a document-specific query language combining LLM techniques with layout-based rules. The REST API exposes extract, classify, fill, generate and document-management endpoints, with SDKs for Node, Python and Go.

Sensible publishes 9 API contracts indexed on the APIs.io network, including Account API, Classify API, Configs API, and 6 more. Tagged areas include Artificial Intelligence, Document AI, Intelligent Document Processing, Extraction, and LLM.

The Sensible catalog on APIs.io includes 1 Spectral governance ruleset.

Sensible’s developer surface includes authentication, documentation, pricing, GitHub presence, engineering blog, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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)	covered	12.1 (thin)	-	-
PDF and Document Standards (PDF tooling, document signing trust, invoice documents)	covered	12.1 (thin)	-	-
Raycast Store Extensions (first-party publishers + community-wrapped products)	covered	12.1 (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 3

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.
