## Summary - Introduces a pluggable `WebSearchDriver` abstraction (interface, factory, service, module) so web search is no longer tied to native provider tools (Anthropic/OpenAI) - **Exa** is the first driver implementation with support for category-filtered search (company, people, news, research paper, etc.) — particularly useful for CRM workflows - Per-query billing for both Exa ($0.007/query) and native provider surcharges ($0.01/query for Anthropic/OpenAI) via the existing `USAGE_RECORDED` pipeline - New config variables: `WEB_SEARCH_DRIVER` (EXA/DISABLED), `EXA_API_KEY`, `WEB_SEARCH_PREFER_NATIVE` (default false — prefers Exa over native when both available) - `WEB_SEARCH` operation type added for usage tracking and Stripe metering ### Architecture ``` WebSearchDriver (interface) ├── ExaDriver — Exa neural search with category support └── DisabledDriver — throws when search is disabled WebSearchDriverFactory (extends DriverFactoryBase) └── creates driver based on WEB_SEARCH_DRIVER config WebSearchService (facade) ├── search(query, options?, billingContext?) ├── isEnabled() └── emits USAGE_RECORDED events per query WebSearchTool (Tool implementation) └── registered in ActionToolProvider, available via tool catalog ``` ### Native search billing gap fixed Anthropic and OpenAI both charge $0.01/search on top of token costs. The token costs were already billed, but the per-call surcharge was not. Added `countNativeWebSearchCallsFromSteps` utility + `billNativeWebSearchUsage` to `AiBillingService`, wired into both chat and workflow agent paths. ## Test plan - [ ] Set `WEB_SEARCH_DRIVER=EXA` + `EXA_API_KEY=...` and verify AI chat can search the web - [ ] Verify category parameter works (ask about a specific company/person) - [ ] Set `WEB_SEARCH_DRIVER=DISABLED` and verify search tool is not exposed - [ ] Set `WEB_SEARCH_PREFER_NATIVE=true` with Anthropic model and verify native search is used - [ ] Verify usage events are emitted in ClickHouse for both Exa and native search paths - [ ] Verify existing billing tests pass (`npx jest ai-billing.service.spec.ts`) Made with [Cursor](https://cursor.com) --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: claude[bot] <41898282+claude[bot]@users.noreply.github.com>

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
