Add Exa provider

Port from upstream CodexBar v0.74.1. Upstream plugin, descriptor, and plugin tests are the spec.

Behavior

  • Service key plus API key ID; reads the key's month-to-date usage (UTC month) and rejects a period that differs from the request, as upstream does.
  • Section "API key this month (UTC)": Spend in USD, no bar. Login "Service key".
  • 401: "Exa rejected the service key. Ordinary search API keys are not supported."

Matches the Mac v0.74.1 captures for success and 401.

Checks (local full-checks.sh on the tree pushed as d7de4678c)

  • cargo fmt --all -- --check: clean
  • cargo test --manifest-path rust/Cargo.toml: 4168 passed, 1 ignored
  • cargo clippy on both manifests with -D warnings: clean
  • cargo test --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml: 708 passed
  • pnpm test, tsc, pnpm run build (apps/desktop-tauri): pass
    Log: W:/mac-parity/report/provider-exa/checks-e6d0614dd/SUMMARY.txt

Review follow-up (d7de4678c)

  • Rebased onto the updated Tavily branch (Add Tavily provider #840).
  • EXA_API_KEY_ID fallback, UTF-8 percent-encoding, the exa workspace provider mapping, and billing periods compared by instant (offsets accepted).
  • Month start and end now come from one now (test month_range_comes_from_one_instant), and body read errors keep their cause. Rebased onto Tavily d9a3e39. Frontend tests passed on re-run after the TrayPanel.period.test.tsx timer flake.
  • Frontend: 1106 Vitest tests passed; tsc and pnpm run build pass.

Windows proof

Recaptured at 1a5aff6b5 (W:/mac-parity/report/provider-exa/proof-1a5aff6b5/COMPARISON.md): tray shows Spend $45.67 as before; Settings shows the saved API key ID test-key-id loaded through the exa workspace mapping. Earlier capture below for reference.
Fresh proof build from the pre-review head, captured against mock routes:
W:/mac-parity/report/provider-exa/proof-e6d0614dd/COMPARISON.md.

Summary by CodeRabbit

  • New Features
    • Added Tavily and Exa as supported providers for tracking usage. Tavily displays account-plan and API-key usage, with pay-as-you-go details when available; Exa displays monthly spend for a selected API key.
    • Added provider setup guidance and Exa API key ID configuration.
  • Improvements
    • Provider usage settings now omit metrics marked as hidden on the provider card.

📝 Walkthrough

The change adds Tavily and Exa as usage providers, including usage retrieval, configuration, registration, and desktop presentation. It also filters usage windows marked hiddenOnCard from usage descriptors and settings rows.

Changes: Tavily and Exa usage providers

Layer / File(s) Summary
Provider identities and configuration
rust/src/core/provider.rs, rust/src/settings/api_keys.rs, rust/src/settings/provider_workspace.rs, rust/src/core/token_accounts.rs
Adds both provider IDs, names, CLI parsing, and brand colors. Adds API-key configuration and Exa workspace-value validation. Both providers return no token-account support.
Tavily usage retrieval and parsing
rust/src/providers/tavily/mod.rs
Fetches and parses account-plan and API-key usage, with optional pay-as-you-go values. Auto and OAuth sources are supported; Web and CLI sources are unsupported.
Exa monthly spend retrieval and parsing
rust/src/providers/exa/*
Fetches usage for a selected API key over the UTC month-to-date period. Validates the returned spend and period. Auto and OAuth sources are supported; Web and CLI sources are unsupported.
Provider registration and presentation
rust/src/core/provider_factory.rs, rust/src/providers/mod.rs, apps/desktop-tauri/src/components/providers/*, apps/desktop-tauri/src/test/providerCatalog.ts, apps/desktop-tauri/src/i18n/keys.ts, apps/desktop-tauri/src/surfaces/settings/providers/sections/credentials/*, rust/src/locale*, README.md, docs/PROVIDERS.md, pr-body-exa.md
Registers both implementations and adds desktop icons, test catalog entries, Exa settings localization, and provider documentation.

Card-hidden usage windows

Layer / File(s) Summary
Filter hidden usage windows
apps/desktop-tauri/src-tauri/src/commands/usage_items.rs, apps/desktop-tauri/src-tauri/src/commands/tests.rs, apps/desktop-tauri/src/surfaces/settings/providers/sections/UsageSection.tsx, apps/desktop-tauri/src/surfaces/settings/providers/sections/UsageSection.test.tsx
Excludes windows marked hiddenOnCard from usage descriptors and settings rows. Tests verify that visible secondary and additional-budget windows remain displayed.

Merge Risk: 🔵 Low · up to 1a5af

An Exa usage refresh could fail at the UTC month boundary. This narrow issue is worth fixing, but does not otherwise prevent merging.

Full details: Provider Data Stays Siloed

Explanation

The pull request still adds provider-specific branching in shared code outside the allowed paths. The diff adds ProviderId::Exa validation in rust/src/settings/provider_workspace.rs and adds ProviderId::Tavily and ProviderId::Exa to shared token-account matching in rust/src/core/token_accounts.rs. The standing failure is therefore unresolved.

Resolution

Remove these provider-specific branches from shared behavior code. Move Exa workspace-ID validation and token-account capability decisions behind provider-local implementations or a generic capability interface, with only rust/src/core/provider_factory.rs selecting providers. Keep provider data and account handling within each provider module and its account context.

Review comments at @rust/src/providers/exa/mod.rs:
- Around line 119-125: Update the encoding logic for `encoded_key_id` to
percent-encode every byte of each UTF-8 character rather than casting `char` to
`u8`. Preserve the existing unescaped-character set and uppercase
percent-encoding format.
- Around line 81-96: Update the key ID resolution in the Exa provider to read
`API_KEY_ID_ENV` when `ctx.workspace_id` is unset or blank. Preserve
workspace-value precedence and apply the existing trimming and invalid-value
checks to whichever source is selected.
- Around line 279-283: Update the assertion in test_parse_valid_usage to check
that the detail’s id is “spend” instead of expecting its title to be “Spend”;
keep the title set by ProviderDisplayDetail::new unchanged.

Review comments at @rust/src/providers/tavily/mod.rs:
- Line 272: Clamp the remaining-credit calculations in the plan, API key, and
pay-as-you-go detail rows to zero so reported remaining values are never
negative. Update the calculations using plan_limit and plan_usage, limit and
key_usage, and paygo_l and paygo_u; preserve the existing row labels and
formatting.

- Around line 91-101: Update the month-start calculation to derive it from the
existing now value rather than calling Utc::now() again. Build the first day of
that date’s month at midnight using date_naive and and_hms_opt, and propagate

Finesssee and others added 12 commits October 13, 2026 11:55
- Add ExaApiTitle, ExaApiKeyIdLabel, ExaApiKeyIdPlaceholder, ExaApiKeyIdHelp locale keys to all 10 language files
- Add Exa case to OpenAiExtras.tsx WORKSPACE_EXTRA_IDS and extraConfig()
- Register locale keys in rust/src/locale.rs and apps/desktop-tauri/src/i18n/keys.ts
- Update Exa provider error message to upstream verbatim: 'Set the Exa API key ID in Scope or EXA_API_KEY_ID; this is not the service key.'
- All Exa provider tests passing (11/11)
- cargo fmt, cargo clippy passing with no warnings
Read EXA_API_KEY_ID as a fallback, percent-encode UTF-8 bytes, map the exa workspace provider, and compare billing periods by instant.
Build the month start from the same now as the end time, and keep body read errors instead of reporting a parse failure.
