Manually translating a large OpenAPI or Swagger document into function definitions is tedious, error-prone and expensive in tokens, especially when an API exposes dozens or hundreds of endpoints. The platform automates that translation, producing compact function-call parameters that AI models can consume without bloating the context window. Because oversized schemas eat into the context budget on every request, EasyFunctionCall positions token optimisation as a core benefit. By generating leaner parameter structures, teams can fit more tools into a single model call and control inference costs as their API surface grows. The result is a faster path from an existing REST API to an AI agent or assistant that can actually take action. The service is aimed at backend and AI engineers, integration specialists and product teams shipping autonomous workflows. It supports common model providers and works with standard specification formats, so it slots into existing documentation pipelines rather than replacing them. **Pricing & Plans:** Freemium. A free tier is available to convert specifications and try the workflow, with paid plans for higher volumes and production use. Check the site for current limits. - **OpenAPI and Swagger conversion:** Ingest standard OpenAPI or Swagger specifications and export function-call parameters ready for AI model tool use. - **Token-efficient output:** Generates compact parameter definitions that reduce the context cost of exposing large API surfaces to language models. - **Multi-model support:** Designed to work with popular model endpoints including ChatGPT/OpenAI, Claude, Gemini and Llama family models. - **SaaS, no local setup:** A hosted web service, so teams can convert specs through the browser without maintaining parsing infrastructure. - **Fits existing docs workflows:** Works from the API specifications development teams already maintain, avoiding duplicate schema authoring. **Strengths:** Saves significant token budget when exposing many endpoints to a model; Removes repetitive manual function-schema authoring; Works with the OpenAPI/Swagger specs teams already have; Supports several major model providers **Limitations:** Value depends on having a well-formed API specification to begin with; Developers still need to validate generated parameters against model-specific quirks; Hosted SaaS means API specs leave your environment unless handled carefully [Profile (Markdown)](https://openaitools.app/tool/easyfunctioncall.md) ## Speechify Speechify is a voice AI assistant built around listening, reading and writing with your voice.
