v1.2.0

Added

• Anthropic API support: ask2api now supports Anthropic's Claude models (Opus 4.6, Sonnet 4.5, Haiku 4.5) in addition to OpenAI
• Provider selection: New ASK2API_PROVIDER environment variable to explicitly choose between openai and anthropic
• Provider-agnostic API key: New ASK2API_API_KEY environment variable that works with any provider
• Anthropic-specific functions:
  • convert_schema_to_anthropic_tool() - Converts JSON Schema to Anthropic tool definition
  • build_anthropic_payload() - Builds API payload using tool calling format
  • build_anthropic_headers() - Sets Anthropic-specific headers (x-api-key, anthropic-version)
  • parse_anthropic_response() - Extracts structured output from tool_use response
  • prepare_anthropic_image_content() - Handles Anthropic's image format
  • convert_content_for_anthropic() - Converts multimodal content between formats
• Provider constants: OPENAI_BASE_URL, ANTHROPIC_BASE_URL, OPENAI_DEFAULT_MODEL, ANTHROPIC_DEFAULT_MODEL, ANTHROPIC_VERSION
• Intelligent API key fallback: Automatically falls back to ANTHROPIC_API_KEY or OPENAI_API_KEY based on selected provider
• Vision support for Anthropic: Image analysis works with both URL and base64-encoded local files
• Enhanced help text: CLI help now shows provider-specific environment variables

Changed

• Config class refactored: Added provider field with automatic provider-specific defaults
• Provider routing: generate_api_response() now routes between OpenAI and Anthropic based on configuration
• Image handling: prepare_image_content() now accepts provider parameter for format-specific handling
• Function naming: Renamed OpenAI-specific functions for clarity:
  • build_payload() → build_openai_payload()
  • build_headers() → build_openai_headers()
• Response parsing: Extracted OpenAI response parsing into parse_openai_response() function
• Default provider: Defaults to openai when no provider is specified (100% backward compatible)
• Documentation: Updated README with comprehensive provider support guide and examples

Technical Details

• Anthropic support uses tool calling to achieve structured output (no native json_schema format)
• Single-file architecture maintained (~330 → 501 lines)
• Zero new dependencies (still only requests)
• Clean separation between OpenAI and Anthropic code paths

v1.1.3

Added

• README: Note warning that some API providers may require base64-encoded images (local files) instead of image URLs; added example commands (curl/wget) to download images and use local files with ask2api.

v1.1.2

Fixed

• Added license field to pyproject.toml for proper pip metadata display

v1.1.1

Added

• generate_api_response function to streamline API response generation using OpenAI format
• build_payload function for better organization of request payload construction
• build_headers function for better organization of request headers construction
• System prompt constant variable for improved maintainability

Changed

• Refactored main function to utilize new response generation logic for enhanced code clarity
• Improved code organization and maintainability through function extraction

v1.1.0

Added

• File input support for prompts: -pf / --prompt-file option to read prompts from text files
• File input support for examples: -ef / --example-file option to read JSON examples from text files
• read_text_file utility function for reading file contents
• Dynamic help text generation for environment variables in CLI
• Metadata documentation for Config dataclass fields

Changed

• Prompt input now supports both direct string (-p) and file input (-pf) as mutually exclusive options
• Example input now supports both direct string (-e) and file input (-ef) as mutually exclusive options
• Enhanced Config dataclass with field metadata for better documentation
• Improved CLI help output with get_env_vars_help method

v1.0.0

Added

• Example input support: -e option to accept JSON examples directly without schema files
• Dynamic schema generation from JSON examples via convert_example_to_schema function
• Support for complex nested structures with automatic type inference
• Type hints mapping for common type names (string, int, float, bool, array, object)

Changed

• Schema input is now optional when using -e flag
• Made -sf and -e mutually exclusive options

v0.3.0

Changed

• Refactored API configuration to use Config dataclass for better maintainability
• Replaced hardcoded API settings with configurable values
• Added environment variable support for API configuration:
  • ASK2API_BASE_URL - Override the base API URL (default: https://api.openai.com/v1)
  • ASK2API_MODEL - Override the model name (default: gpt-4.1)
  • ASK2API_TEMPERATURE - Override the temperature setting (default: 0)
