Summary

Add TinyFish Search as an optional managed engine behind phaseo:web_search.

What changed

  • Add opt-in engine: "tinyfish" support using the TinyFish Search API.
  • Support localized queries, result pagination, bounded result counts, and shared domain filters.
  • Normalize TinyFish results into the existing Phaseo search result shape, including snippets as highlights.
  • Keep TinyFish usage observable while excluding its free provider calls from the billable managed-search meter.
  • Reject insecure custom TinyFish endpoints before sending the API key.
  • Update the canonical request schema, public OpenAPI spec, and generated SDKs.
  • Add TinyFish environment bindings, schema coverage, billing coverage, and deterministic API coverage.
  • Document configuration, limitations, and provider-cost handling.

Validation

  • Focused Vitest suite — passed (95 tests in the final targeted run)
  • pnpm run typecheck — passed
  • Targeted ESLint — passed with existing file-length warnings only
  • pnpm run build — passed Cloudflare dry-run
  • pnpm run openapi:lint — passed with existing warnings only
  • pnpm run docs:openapi:check — passed
  • git diff --check — passed
  • Live TinyFish API smoke test — passed (HTTP 200, 9 results)
  • Live Phaseo server-tool smoke test — passed (3 results, 0 billable search requests)

Release impact

Includes a patch changeset for @phaseo/gateway-api.

TinyFish Search is documented as free on its published plans, so this integration does not add a provider usage charge for TinyFish Search while normal Phaseo request and token pricing remains applicable.

📝 Walkthrough

Walkthrough

Adds TinyFish as a managed web-search engine with localized pagination, domain-filter translation, configuration bindings, SDK and OpenAPI updates, execution tests, and non-billable usage accounting.

Changes

TinyFish Search

Layer / File(s) Summary
Search contract and provider configuration
apps/api/src/core/schemas.ts, apps/api/src/runtime/env.*, apps/docs/openapi/v1/*, packages/sdk/sdk-ts/src/oapi-gen/*, apps/docs/v1/guides/*, .changeset/add-tinyfish-search.md
Web-search definitions support tinyfish, language, and pages from 0 through 10. Environment bindings, SDK types, OpenAPI schemas, guides, tests, and release metadata describe the new options.
TinyFish request execution
apps/api/src/pipeline/surfaces/server-tools.ts, apps/api/src/pipeline/surfaces/server-tools.test.ts, apps/api/src/core/__tests__/schemas-text-validation.test.ts
The server-tool pipeline resolves TinyFish configuration, translates domain filters, sends authenticated requests, normalizes results, handles errors, and validates parsed parameters.
Billable search usage propagation
apps/api/src/pipeline/surfaces/server-tools.ts, apps/api/src/pipeline/surfaces/text-generate.ts, apps/api/src/pipeline/surfaces/server-tools.test.ts
Provider-specific billable request counts flow through server-tool rounds and raw usage. TinyFish reports zero billable search requests.

Estimated code review effort: 4 (Complex) | ~45 minutes
