feat(diffbot): add Diffbot plugin with extract and search endpoints - #1009
Conversation
- Extract Article: extract title, text, author, date and metadata from any URL - Extract Product: extract price, availability, images and specs from e-commerce URLs - Extract Analyze: auto-detect page type and extract structured data - Search Web: full-text web search with structured article results - Search DQL: query the Diffbot Knowledge Graph with DQL - Auth: API key via ?token= query parameter (Diffbot standard) - Schema: DiffbotArticle and DiffbotProduct Zod entities - Registered in packages/corsair/core/constants.ts

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The plugin can send requests with a caller-supplied token instead of the configured credential, and it still accepts collection searches that may generate invalid upstream requests. These bounded correctness and credential-handling risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@packages/diffbot/client.ts`:
- Around line 34-36: Update the OpenAPIConfig/request construction around
DIFFBOT_API_BASE so DQL requests use the Knowledge Graph base URL while other
requests retain the existing API host; add per-request base-URL selection for
search.dql and tests asserting the constructed kg.diffbot.com host and
/kg/v3/dql path.
- Around line 65-68: Update the request error handling around the catch block to
preserve ApiError status and retryAfter metadata when converting or rethrowing
errors, ensuring RATE_LIMIT_ERROR still detects 429 responses and
headersRetryAfterMs receives retryAfter. Add coverage verifying retryAfter is
retained.
In `@packages/diffbot/endpoints/search.ts`:
- Around line 29-38: Update the search handler’s input schema and destructuring
so the entity filter is named entityType and execution mode is represented by a
queryType enum; use entityType only when building the DQL prefix, and forward
queryType as the HTTP type parameter in makeDiffbotRequest. Add a request test
covering crawl mode with a collection (col) query.
In `@packages/diffbot/webhooks/types.ts`:
- Around line 56-61: Update verifyDiffbotWebhookSignature to fail closed by
returning an invalid result unless request.hubVerified is true; do not return
valid based only on the presence of a signature header or payload. Ensure the
externally reachable Diffbot webhook is not registered when Hub verification is
unavailable.

- client.ts: re-throw ApiError directly to preserve .status and .retryAfter metadata so RATE_LIMIT_ERROR handler can read 429 status and headersRetryAfterMs correctly; add Knowledge Graph base URL (kg.diffbot.com/kg/v3) for DQL endpoint routing - endpoints/search.ts: route search.dql to kg.diffbot.com/kg/v3/dql; separate entityType (DQL query prefix) from queryType (HTTP execution mode: query/text/crawl/queryTextFallback) per Diffbot API docs - endpoints/types.ts: rename DQL input field type->entityType, add queryType enum for HTTP execution mode; crawl+col combo now supported - webhooks/types.ts: fail-closed signature verification — only accept events where request.hubVerified is true; prevents forged webhook events via x-diffbot-signature header spoofing - api.test.ts: update DQL tests for renamed fields; add crawl mode and invalid queryType coverage (24 tests total, up from 22)

Description
Adds the
@corsair-dev/diffbotplugin package, integrating Diffbot — a web data extraction and knowledge graph API — into the Corsair ecosystem.##What was built
5 real API endpoints grouped into two namespaces:
extract.articleextract.productextract.analyzesearch.websearch.dqlAuth: API key passed as
?token=<key>query parameter (Diffbot standard).Schema entities:
DiffbotArticleandDiffbotProductZod schemas for optional local caching.Tests: 22 assertions across 2 test files covering input validation, output parsing, and edge cases for all 5 endpoints.
Closes #1001
