Angular Velocity Calculator API

science 1 credit / call v2026-04-22

Convert angular velocity between rad/s, RPM, Hz, deg/s, and period, or derive it from linear speed and radius with tangential and centripetal results.

One POST adds Angular Velocity Calculator to your app, site, workflow, or agent — formula, validation, edge cases, and docs already handled.

faq frequently asked
What does the Angular Velocity Calculator API do?+

Convert angular velocity between rad/s, RPM, Hz, deg/s, and period, or derive it from linear speed and radius with tangential and centripetal results. Use it to add this utility without rebuilding formulas, validation, examples, and documentation.

How much does one call to Angular Velocity Calculator cost?+

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

What parameters does the Angular Velocity Calculator API require?+

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

Is the Angular Velocity 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 Angular Velocity Calculator API?+

Yes. Connect to https://api.miniwebtool.com/v1/mcp over the Model Context Protocol. The agent discovers `angular-velocity-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`.

mcp 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 (angular-velocity-calculator) and its JSON Schema automatically — no client codegen.

# List tools the agent can call
curl -s https://api.miniwebtool.com/v1/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' \
