Add TypeSafe provider with POST /v1/systemone and Jev pricing by tombeckenham · Pull Request #634 · TanStack/schemas

tombeckenham · 2026-11-10T04:54:33Z

Fixes #621

Summary

Adds a typesafe provider. GET /v1/openapi/typesafe is the public document at https://api.typesafe.ai/openapi.json, with POST /v1/systemone classified as decision. The multipart form is dropped so the stored body stays the JSON request TanStack AI sends. model stays an open string.
Lists Jev jev-1.14.0 and jev-1.13.0 from the public models page. Both are $0.042 per million input tokens, and output tokens are free. jev-latest and jev-preview alias jev-1.14.0.

Test plan

bun run test src/server/providers/typesafe-models.test.ts src/server/providers/adapters/typesafe.test.ts src/server/provider-openapi.worker.test.ts
Parsed the live models page and bundled the live OpenAPI document (no extractor warnings, one /v1/systemone endpoint)

Summary by CodeRabbit

New Features
- Added TypeSafe as an AI provider, with support for Jev models and decision requests.
- Added model catalog details, including versioned model names, aliases, context limits, supported inputs, and input-token pricing.
- TypeSafe requests use bearer authentication and retain the JSON request format. Output-token pricing is listed as free.

Walkthrough

This change adds a TypeSafe provider for the Jev decision API. It adapts the provider’s OpenAPI document, configures model retrieval and bearer authentication, and parses the TypeSafe models page into versioned model information with input pricing.

Changes: TypeSafe provider

Layer / File(s)	Summary
Parse and convert Jev model catalog `src/server/providers/typesafe-models.ts`, `src/server/providers/typesafe-models.test.ts`	The parser validates model IDs, prices, context lengths, input modalities, release dates, aliases, and the free-output statement. Conversion creates model information with input-token pricing and zero output-token pricing. Tests cover parsed data, compiled pricing, and invalid catalog content.
Configure provider and adapt OpenAPI `src/server/providers/types.ts`, `src/server/providers/adapters/typesafe.ts`, `src/server/providers/adapters/typesafe.test.ts`, `src/server/providers/adapters/hints.json`, `src/server/provider-openapi.worker.test.ts`	The provider configuration adds bearer authentication, model retrieval, open model names, and decision generation at `/v1/systemone`. The adapter removes multipart input from the endpoint while preserving JSON and rejects missing or invalid JSON request bodies. Tests check classification, bundling, schema validation, and the generated OpenAPI document.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · up to 4192d

A future models-page edit could interrupt catalog updates or record an incorrect release date. Limit the release match to one paragraph before merging, or accept this bounded risk.

Full details: Linked Issues check

Explanation

#621 asks for a TypeSafe provider, an OpenAPI document for POST /v1/systemone, and Jev models with pricing. The provider config uses the TypeSafe API base and bearer authentication, publishes the upstream OpenAPI source, classifies /v1/systemone as decision, and keeps model names open. Its adapter preserves the JSON request body and removes the multipart alternative. The supplied test summaries cover OpenAPI assembly, request and response schemas, and decision classification. The model parser and tests cover Jev versioned IDs, aliases, input pricing, and zero output pricing. These changes address the linked coding requirements, including the GET /v1/openapi/typesafe acceptance criterion.

Explanation

The changes described in the PR add the TypeSafe adapter and API key, parse and price the Jev catalog, and test the provider behavior. Each change supports #621. The available evidence shows no unrelated changes.

Full details: Docstring Coverage

Explanation

Docstring coverage is 75.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 6 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

pr-summarise verdict: Fix, one item. The PR conflicts with main: src/server/providers/types.ts conflicts with #633, which added FISH_AUDIO_API_KEY next to the new TYPESAFE_API_KEY. Please rebase onto main and keep both keys. provider-openapi.worker.test.ts auto-merges. Nothing else is blocking: the spec is upstream, the multipart strip fails loud when there's no JSON body, the models-page parser throws on any unread row, and it reuses #632's decision activity and openModelNames. I'll re-run pr-summarise on the rebased head and merge only on Approve.

The public OpenAPI document is assembled at GET /v1/openapi/typesafe. Jev 1.14.0 and 1.13.0 are decision models at $0.042 per million input tokens, with output tokens free. jev-latest and jev-preview alias 1.14.0.

Keep the release match within one paragraph.

An unrelated earlier “is the newest” statement can match the Jev release date and make parseTypesafeModels throw. If the Jev sentence loses its date, the regex can instead assign a later paragraph’s date to Jev. That date can also backdate firstSeenAt.

Limit the match to one paragraph while allowing a sentence to wrap across lines.

Proposed fix

- /([A-Z][\w .'-]*?) is the newest\b[\s\S]*?available from ([A-Z][a-z]+ \d{1,2}, \d{4})/, + /([A-Z][\w .'-]*?) is the newest\b(?:(?!\r?\n[ \t]*\r?\n)[\s\S])*?available from ([A-Z][a-z]+ \d{1,2}, \d{4})/,
