upfetch

Use up-fetch when you need a reusable fetch client with request-scoped defaults, automatic request/response shaping, runtime validation, retries, and lifecycle hooks.

Mental model

• up(fetchFn, getDefaultOptions?) creates the reusable client.
• getDefaultOptions(input, options, ctx) runs on every request.
• upfetch(input, options?, ctx?) performs one request.
• Keep SKILL.md high-level; load the relevant file under references/ for details.

Minimum pattern

import { up } from 'up-fetch'
import { z } from 'zod'
