Frequently asked

What does the OPS Calculator API do?

Calculate baseball on-base plus slugging with OBP and SLG components. Use it when you need exact JSON instead of asking an LLM to recreate well-defined utility logic.

How much does one call to OPS Calculator cost?

1 credit per successful call. Failed calls (validation errors, 5xx) don't bill.

What parameters does the OPS Calculator API require?

Required fields: (none). Full schema at /v1/openapi.json.

Is the OPS Calculator API deterministic?

Yes — same input, same output, forever. Tool version 2026-04-22; output shape is stable within a major version.

Can an AI agent call the OPS Calculator API?

Yes. Connect to https://api.miniwebtool.com/v1/mcp over the Model Context Protocol. The agent discovers `ops-calculator` with its JSON Schema automatically, so the model can plan while MiniWebtool handles the exact tool result.

What format does the API return?

JSON with a stable envelope: `{request_id, tool, tool_version, credits_used, result}`. Errors are RFC 7807 `application/problem+json`.

Use from an AI agent

Every endpoint on this site is also exposed via the Model Context Protocol at https://api.miniwebtool.com/v1/mcp. Claude, Cursor, and any MCP-capable agent can discover this tool (ops-calculator) and its JSON Schema automatically — no client codegen.
