SDKs

The ISA SDK is the supported way to call the platform. It handles authentication, idempotency keys, automatic retry on 5xx/429, cursor pagination, webhook signature verification, and local dataset accessors (match, autocomplete, autocorrect). You never reimplement these — one package per language, generated from the same OpenAPI contract that drives the API reference.

Pick your language below, install the package, and follow the quickstart. In under five minutes, you'll go from an empty project to a 200 response from POST /v3/prequalify for John Doe (NC, born 1962-04-18).

Install and start

Zero to first 200

Each language has an end-to-end tutorial. It takes you from an empty project to a prequalify decision, covering auth, error handling, and production readiness — no insurance domain knowledge required.

Dataset accessors

The SDK resolves medication, condition, and concept text against the licensed dataset locally. No extra HTTP round trip, no consumer-side make_key lookups. These are the same accessors that power picker UIs in production.

• Match — resolve text to a canonical Concept or an UnknownConcept, with a replaceable MatchAlgorithm.
• Autocomplete — ranked suggestion lists for picker UIs, six-bucket priority with a replaceable AutocompleteAlgorithm.
• Autocorrect — SDK-side typo correction bound to the dataset's spelling table, replaceable per instance.
• Reference: match accessors — the three Concept accessors and when to reach for each.
• Reference: dataset catalog — the /v3/datasets wire shape, ULID identifiers, and ?include= slicing.

Build on it

Once you've constructed the client, these guides cover the cross-cutting concerns the SDK handles:
