httpFallback

import { httpFallback } from "@hellohelen-ai/goliath";

const fallback = httpFallback({ url, headers, fetch, readText });

Option	Type	Notes
url	string	Posted to with content-type: application/json
headers	Record<string, string> | () => Promise<Record<string, string>>	Static, or a function when the token rotates
fetch	typeof fetch	Override for tests. Defaults to the global fetch
readText	(body: unknown) => string	Pull the answer out. Default reads { text }

The payload

The request body is a FallbackPayload: a FallbackRequest without signal.

type FallbackPayload = {
  ask: string;
  summary: string;
  recent: Exchange[];
  steps: StepRecord[];
  reason: EscalationReason;
  error?: string;
};

A non-2xx response throws httpFallback: <status> from <url>. A body without a text string throws unless readText is set.
