get_endpoint_schema
Retrieve OpenAPI schema for specific API endpoints to understand request parameters, response structures, and required fields for development.
Instructions
šÆ GET PRECISE ENDPOINT SCHEMA - Returns exact OpenAPI schema for specific endpoints.
Perfect for when you need:
ā¢ Exact request parameter names and types
ā¢ Response field names and structures
ā¢ Required vs optional parameters
ā¢ Related endpoints for the same use case
Example queries this replaces:
ā¢ "bills endpoint response schema fields amount vendor status" ā Use this tool with /developer/v1/bills
ā¢ "API pagination limit page_size next cursor" ā Get schema for any paginated endpoint
ā¢ "cards creation request parameters" ā Use this tool with /developer/v1/cards
Usage: Provide an endpoint path (and optionally method) to get the complete technical specification.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| endpoint | Yes | The endpoint path (e.g., '/developer/v1/bills', '/developer/v1/limits') | |
| method | No | HTTP method (GET, POST, PUT, etc.). If not specified, will show most relevant method. | |
| include_related | No | Include related endpoints for the same use case |
Implementation Reference
- src/tools/get_endpoint_schema.py:83-118 (handler)Main execution handler that parses input, finds matching endpoints, handles errors, and formats the schema response as TextContent.
