API reference

Base URL

The base URL is this origin: https://getowed.fun. /gateway/v1 is an alias for /v1 if you prefer an explicit path. Authentication is the header the vendor expects, carrying the owed_ key in place of theirs.

Endpoints

OpenAI-compatible vendors

OpenAI, DeepSeek, xAI, Mistral, Meta, Cohere, Perplexity, and Moonshot all share the chat-completions contract. Point the OpenAI SDK at this origin and set the model to the one you locked at settle time.

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.OWED_KEY,        // owed_…
  baseURL: "https://getowed.fun/v1",
});

const res = await client.chat.completions.create({
  model: "gpt-5.2-mini",
  messages: [{ role: "user", content: "Summarise this diff" }],
  stream: true,
});

for await (const chunk of res) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}

Anthropic

Anthropic uses its own messages contract and the x-api-key header. The SDK needs the origin without a version suffix.

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: process.env.OWED_KEY,
  baseURL: "https://getowed.fun",
});

await client.messages.create({
  model: "claude-sonnet-4-6",
  max_tokens: 512,
  messages: [{ role: "user", content: "Hello" }],
});

Google

Use the official generateContent path against this origin, with the key in x-goog-api-key.

curl https://getowed.fun/v1beta/models/gemini-3.0-flash:generateContent \
  -H "x-goog-api-key: $OWED_KEY" \
  -H "content-type: application/json" \
  -d '{"contents":[{"parts":[{"text":"Hello"}]}]}'

Using a key in Cursor

Cursor accepts an OpenAI-compatible base URL. Set the override to https://getowed.fun/v1, paste the owed_ key as the API key, and pick the model you locked. When the cap is spent, requests return 402 and nothing silently falls back to a paid account.
