CLI Proxy API — fork

Fork of router-for-me/CLIProxyAPI. For project overview, sponsors, ports, and the full feature set, see the upstream README.

Patches

Each patch is strict-additive: it only changes behavior when its condition is met.

Patch 1 — reasoning field fallback in OpenAI→Claude response translation

internal/translator/openai/claude/openai_claude_response.go (three call sites).

When reasoning_content is absent or empty in the upstream response, fall back to reasoning. reasoning_content still wins when both are present.

Patch 2 — strip cache_control markers in Claude→OpenAI request translation

internal/translator/openai/claude/openai_claude_request.go (stripCacheControl helper at the top of ConvertClaudeRequestToOpenAI).

Remove cache_control from messages[].content[], system[], tools[], and message-level fields before translation.

Patch 3 — OAuth access tokens use Authorization: Bearer … (Claude executor auth)

internal/runtime/executor/claude_executor.go (two call sites: PrepareRequest and applyClaudeHeaders).

When the credential's API key starts with sk-ant-oat01-, route via Authorization: Bearer … instead of x-api-key. Real sk-ant-api03-* API keys keep the existing x-api-key routing.

Patch 4 — strip Claude entries from the antigravity model catalog

internal/registry/models/models.json and .github/workflows/release.yaml (post-refresh step).

Antigravity's published catalog includes claude-opus-4-6-thinking and claude-sonnet-4-6 because Google's AI Code Assist tier resells Claude models via cloudcode-pa.googleapis.com. With those entries present, an antigravity OAuth becomes eligible alongside the Anthropic OAuth pool when the selector picks for claude-* routes. Session-affinity then pins entire Claude Code sessions (parent + sub-agents) to the antigravity OAuth whenever the parent request was a Gemini call, exhausting Antigravity's small Sonnet quota within hours.

Strip every entry whose id starts with claude-, whose type is claude, or whose owned_by is anthropic from the antigravity array. Applied both to the in-tree models.json (so go test ./... and local dev see the patched shape) and to the release workflow's post-refresh step (so upstream catalog refreshes during tagged builds re-apply the strip automatically). After the patch the antigravity OAuth is Gemini-only and Claude requests fall through to the Anthropic OAuth pool.

Tests

go test ./internal/translator/openai/claude/...                                                     # Patches 1 + 2
go test ./internal/runtime/executor/ -run 'OAuthAccessTokenUsesBearerAuth|ApiKeyStillUsesXApiKey'   # Patch 3
go test ./internal/registry/...                                                                     # Patch 4 (catalog integrity)

Rebase

Monthly intentional bump — no auto-pull. When rebasing:

1. git fetch upstream
2. Cherry-pick or rebase the patches on top of the new upstream tag.
3. go test ./... — the patch tests must pass.
4. Cut a release tag vX.Y.Z-ampeco with a darwin-arm64 binary + .sha256 sidecar attached.
