Headers

You can configure both fixed and dynamic headers for an API configuration.

Usage​

Setting fixed headers​

Example for Automatic1111. The same approach works for other model providers.

import { ollama } from "modelfusion";

const api = automatic1111.Api({
  headers: {
    // setting a fixed user/password authorization header:
    Authorization: `Basic ${Buffer.from(`${user}:${password}`).toString(
      "base64"
    )}`,
  },
});

Setting dynamic call headers​

You can pass a customCallHeaders function into API configurations to add custom headers. The function is called with functionType, functionId, run, and callId parameters.

Example for Helicone. The same approach works for model providers.

import { ollama } from "modelfusion";

const api = new HeliconeOpenAIApiConfiguration({
  customCallHeaders: ({ functionId, callId }) => ({
    "Helicone-Property-FunctionId": functionId,
    "Helicone-Property-CallId": callId,
  }),
});
