Generalize the AI Gateway Worker from 3 hardcoded providers to support
11 additional OpenAI-compatible providers (DeepSeek, Groq, Mistral,
Together, xAI, OpenRouter, Perplexity, Cohere, Fireworks, MiniMax,
Moonshot) via /proxy/{provider}/v1/... routes.
- routing: GENERIC_PROVIDERS whitelist, GENERIC_ENDPOINTS whitelist,
matchGenericRoute() parser
- config: PROVIDER_DEFAULTS with verified base URLs,
getGenericProviderConfig() lookup
- keys: getGenericApiKey() reads from creds.providers[provider].apiKey
- providers/generic: OpenAI-compatible passthrough proxy
- index: generic route handling with auth, key lookup, llemtry telemetry
- admin: mergeCredentials/maskCredentials extended for providers field
- config-ui: collapsible Additional Providers section with 11 API key
fields, 3-segment data-field path support in buildUpdate()
- llemtry: widen ReportOptions.provider to string for generic names
- types: LegacyProvider alias, GenericRouteMatch, providers on
UserCredentials
… generic provider - generic.ts: preserve all request headers (matching openai.ts pattern), only rewrite Authorization; support ProviderConfig with egress proxy URL wrapping and CF header stripping - config.ts: getGenericProviderConfig returns full ProviderConfig with egressProxyUrl and proxy auth headers when configured - index.ts: pass ProviderConfig to proxyGeneric; fix error code for missing API key from 500 to 401 (consistency with generic route)
…ndant log - config.ts: getGenericProviderConfig no longer inherits EGRESS_PROXY_URL; the egress sidecar is a chatgpt.com WAF workaround scoped to openai-codex and should not add an extra hop for generic providers - index.ts: remove redundant console.error on missing API key (already logged by getProviderApiKey via log.warn)
…ove dead code
- config.ts: getGenericProviderConfig now returns CF AI Gateway config
when CF_AI_GATEWAY_* env vars are set, matching legacy provider behavior
- index.ts: compute gateway path for generic routes ({provider}/chat/completions
format, stripping v1/ prefix)
- generic.ts: remove dead egress proxy URL wrapping and CF header stripping
(egress proxy is scoped to openai-codex only); keep config.headers
handling for CF AI Gateway auth header
- generic.ts: strip Cloudflare-injected metadata headers (cf-*) before forwarding to upstream providers (defense in depth) - config-ui.ts: convert early return in buildUpdate to if/else for clarity - README.md: document generic provider routes and 14-provider support - AI-GATEWAY-CONFIG.md: add generic provider credential types, route pattern, and verification example
…gle provider list - Remove unused LegacyProvider type and GenericRouteMatch re-export from types.ts - Extract shared loadCredentials() helper in keys.ts, eliminating duplicate KV read/parse boilerplate - Derive GENERIC_PROVIDERS from exported PROVIDER_DEFAULTS so the provider list is defined once
CF Access headers were silently dropped when EGRESS_PROXY_AUTH_TOKEN was unset because the entire headers object was gated on that var. Extract buildCodexHeaders() that builds each header set independently. Also fix buildUpdate() in config-ui: a parse error in the forEach callback only exited that iteration, allowing a partial update to be submitted. Add hasError flag to abort the entire build and null guard in save().
buildCodexHeaders() used a non-null assertion for CF_ACCESS_CLIENT_SECRET when only CF_ACCESS_CLIENT_ID was checked. Now both must be set or neither Access header is emitted.

Summary
/proxy/{provider}/v1/...routesproviders.*, managed via the Config UIBug fixes (added during review)
buildCodexHeaders()now builds proxy auth and CF Access headers independently. Previously CF Access headers were silently dropped whenEGRESS_PROXY_AUTH_TOKENwas unset.CF_ACCESS_CLIENT_IDandCF_ACCESS_CLIENT_SECRETmust be set or neither Access header is emitted. Previously a missing secret produced a broken header value.buildUpdate()now uses ahasErrorflag to abort on Codex OAuth parse failure instead of submitting a partial update.save()guards against the resultingnullreturn.Depends on #7 (
fix/openai-proxy-headers) — that commit is included in this branch. Once #7 merges, rebasing this branch will drop it cleanly.Test plan
