What the publisher says

From the Budgetary: estimate token spend repository's README, as published. We do not edit it. Read it on GitHub

Budgetary clients

Budgetary tells you how many tokens an LLM query will cost — before you run it.

Budgetary is a hosted API at https://api.budgetary.tools that returns probabilistic pre-inference token-spend estimates for LLM queries. This repository holds the open-source clients that talk to it: language SDKs and editor plugins.

Quick example

import { BudgetaryClient } from "@budgetary/sdk";

const budgetary = new BudgetaryClient({ apiKey: process.env.BUDGETARY_API_KEY! });
const estimate = await budgetary.estimate("Summarize the attached PDF in three bullets.");

The SDK in this release is a stub — the call above illustrates the shape of the API surface, not a working implementation.

Install

See docs/installation.md for per-client setup:

  • TypeScript / JavaScript SDK — @budgetary/sdk on npm
  • Python SDK — budgetary on PyPI
  • VS Code extension (dashboard)
  • Claude Code plugin
  • Codex plugin

API

Bearer-auth HTTP API at https://api.budgetary.tools. The wire contract is published at docs/api-contract.md.

Status

Early access. The hosted API is live, but client interfaces may change between releases until they reach 1.0. Pin exact versions in production.
