apipay is now apifare — same product, same tokens. New home: apifare.com. This address keeps working for 90 days.

apifare × LibreChat

Give every user of your LibreChat instance their own prepaid tool balance: no separate provider account or provider API key for eligible capabilities — one apifare account gives their agent a capped, auditable budget. One YAML block; no LibreChat code changes; off unless the user connects.

The config (works today)

LibreChat's customUserVars prompts each user for their own token and stores it encrypted. Add this to librechat.yaml:

mcpServers:
  apifare:
    type: streamable-http
    url: https://apipay.fly.dev/mcp
    headers:
      Authorization: "Bearer {{APIPAY_TOKEN}}"
    customUserVars:
      APIPAY_TOKEN:
        title: "apifare token"
        description: "Prepaid tool balance - get one at https://apipay.fly.dev (shown once at signup)."

Local/desktop installs can use stdio instead: command: npx, args: ["-y", "apifare-mcp"], env: {APIPAY_TOKEN: "{{APIPAY_TOKEN}}"}. APIPAY_TOKEN is the env name (legacy install id).

What your users see

Each user pastes their token once on the connection screen:

Screenshot incoming — the LibreChat connection screen prompting for the apifare token.

When their balance runs out mid-task, the paywall shows up inside the chat — a human-readable line with the top-up link and the spend cap; after topping up, the task resumes. Failed provider calls are refunded.

Screenshot incoming — the cap-framed 402 rendered on LibreChat's failed-tool card.

Demo film incoming — the full task run inside LibreChat: task → cap → mid-task 402 → approval → completion.

What's callable

The current catalog with exact per-call prices is at /capabilities — the listed number is what the balance is debited (one source of truth, CI-enforced). Spend guardrails live wallet-side: per-agent caps, kill switch, signed audit export.

For operators

You never touch the money — each user funds their own balance. Sign-ups made from your instance can carry "origin":"app:librechat" so we both see the integration working. Questions or a listing/doc conversation: github.com/iamalanlui/apipay.
