Unified AI API documentation, without hidden boundaries.

Quickstart

Point a supported OpenAI client at the EveryModelAPI base URL and use a project-scoped key.

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.EVERYMODEL_API_KEY,
  baseURL: "https://api.everymodelapi.com/v1",
});

const response = await client.responses.create({
  model: "openai/gpt",
  input: "Summarize the release notes.",
});

Authentication

Send the API key in the Authorization: Bearer header. Keep production, staging, batch jobs, and individual developer access on separate keys.

Model IDs

Model IDs use a provider-qualified pattern such as openai/gpt. Stable aliases will have published update policies; version-pinned identifiers will remain available where upstream terms permit.

Errors and request IDs

Every response will include a platform request ID. Preserve it in logs and support tickets. Errors will distinguish authentication, account policy, rate limit, routing availability, upstream rejection, and gateway failure.
