feat:Add Anthropic POST endpoints and supporting schemas to openapi.yaml #230

HavenDV · 2025-09-24T18:25:39Z

Summary by CodeRabbit

New Features
- Added API endpoints to interact with Anthropic models:
  - POST /anthropic/v1/messages for sending messages (supports system prompts, tools, streaming, and configurable parameters).
  - POST /anthropic/v1/messages/count_tokens for estimating token usage.
Documentation
- Updated API specification to include the new endpoints with request/response definitions and supported options.

Walkthrough

Added two Anthropic-related POST endpoints to the OpenAPI spec and introduced several supporting schemas (messages input, token count request, system content, thinking config, tool). Request bodies reference the new schemas, with standard 200/422 responses. All changes are confined to src/libs/DeepInfra/openapi.yaml.

Changes

Cohort / File(s)	Summary
OpenAPI: Anthropic endpoints and schemas `src/libs/DeepInfra/openapi.yaml`	Added POST `/anthropic/v1/messages` and `/anthropic/v1/messages/count_tokens` with header params and request bodies. Introduced schemas: `AnthropicMessagesIn`, `AnthropicTokenCountRequest`, `AnthropicSystemContent`, `AnthropicThinkingConfig`, `AnthropicTool`. Wired schemas into endpoints and components with cross-references.

Poem

I thump my paw: new paths appear,
Two posts to call, both crisp and clear.
Schemas bloom like clover bright,
Tools and thoughts in tidy light.
Tokens counted, messages sent—
A hop, a skip, well-documented! 🐇✨

Pre-merge checks and finishing touches

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title Check	❓ Inconclusive	The title “feat:@coderabbitai” is vague and doesn’t describe the primary changeset details, so it doesn’t convey the added API endpoints or schemas. It uses a generic feature prefix and a team mention without summarizing the contents.	Consider renaming the pull request to clearly describe the main changes, for example “Add Anthropic messaging and token counting endpoints to OpenAPI spec.”

⚠️ Potential issue

Mark max_tokens as required for Anthropic requests.

POST /anthropic/v1/messages rejects requests that omit max_tokens (same as Anthropic’s upstream contract). Because the schema doesn’t list it as required, auto-generated clients will happily drop the field and hit runtime 400s. Please add it to the required array so the spec matches the actual behavior.

required: - model - messages + - max_tokens

🤖 Prompt for AI Agents

In src/libs/DeepInfra/openapi.yaml around lines 4867 to 4933, the AnthropicMessagesIn schema omits max_tokens from the required array which causes generated clients to omit it and receive 400s; update the schema by adding max_tokens to the required list for AnthropicMessagesIn so the OpenAPI spec mandates the field and aligns with the upstream Anthropic behavior.
