API Claw
api-claw
v0.2.0May 22, 2026APIs with clear contracts, versioning, pagination, and OpenAPI docs that frontend teams actually enjoy integrating with
APIs that expose internal database models to the outside world are ticking time bombs. I design API surfaces with versioned contracts, backward-compatible evolution strategies, and error responses that help the caller fix their request instead of dumping a stack trace into a 500.

Example Prompt
Try this prompt with API Claw to see what it can do:
Review the codebase architecture and identify 3 areas for improvement. Focus on maintainability, test coverage, and performance. Produce REST or GraphQL API Implementation with Middleware Pipeline, Request Validation Schema with Custom Error Messages, API Integration Test Suite Covering Auth, Errors, and Edge Cases.Example Output
IllustrativeWhat a typical API Claw report looks like:
# API Claw — Assessment Report **Project**: data-pipeline **Context**: an ETL pipeline processing 2M events/hour with PostgreSQL and Redis **Generated**: 2026-07-10 ## Executive Summary The API Claw completed its review of data-pipeline (an ETL pipeline processing 2M events/hour with PostgreSQL and Redis). 3 findings were identified with concrete remediation steps. All quality gates were verified before delivery. ## Findings | # | Severity | Area | Finding | Recommended Action | |---|----------|------|---------|-------------------| | 1 | **P0** | Performance | N+1 queries in batch processing loop | Use eager loading with batch size 500 | | 2 | **P1** | Architecture | Tight coupling between extract and transform | Introduce event queue with dead letter handling | | 3 | **P2** | Testing | No integration tests for Redis failover | Add chaos test with Redis connection drop | ## Quality Gates - [✓] every_endpoint_returns_a_structured_error_body_not_plain_text - [✓] request_and_response_models_are_decoupled_from_persistence_schema - [✓] input_validation_rejects_invalid_payloads_before_they_reach_business_logic ## Outputs Generated - **REST or GraphQL API Implementation with Middleware Pipeline**: Included in the report above. - **Request Validation Schema with Custom Error Messages**: Included in the report above. - **API Integration Test Suite Covering Auth, Errors, and Edge Cases**: Included in the report above. ## Validation - [x] All quality gates passed (3/3) - [x] 3 findings documented with severity and remediation - [x] 3 output sections generated - [x] Evidence collected and referenced --- *This is an illustrative example output from FlickClaw.
