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 8 APIs on the APIs.io network, including Account API, Classify API, Configs API, and 5 more. Tagged areas include Artificial Intelligence, Document AI, IDP, Extraction, and LLM.

Sensible’s developer surface includes authentication, documentation, pricing, GitHub presence, engineering blog, and 10 more developer resources.

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.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sensible-io: open an issue to ask a question, or submit a pull request to add artifacts.
