API base

One endpoint. Bring the OpenAI SDK you already use.

Point any OpenAI-compatible client at the SuperbAPI base URL and pass your key. Account, billing, and support live in the workspace — your code only ever talks to one route.

Base URL https://www.superbapi.com/v1

How it works

One integration. Every model. Full control.

Wire up SuperbAPI once, then switch models, scope keys, and track spend without touching your code again.

One endpoint, every model

Point any OpenAI-compatible client at one base URL. Change the model field to switch between Claude, Gemini, and dozens more — same key, same code.

Scoped keys, real limits

Generate a key per app or customer. Set a monthly budget, an expiry date, and an allowed-model list on each — edit them any time.

One prepaid wallet

Top up once. Every call draws from a single balance at the model's exact rate — with tokens and spend visible per key. No subscription, and 0% service fee until 31 Dec 2026.

Prepaid credit

Top up once, spend across every model.

Pay only for what you use. There is no subscription and no monthly minimum — buy credit, and each API call draws down your balance at that model's rate.

0% service fee
No platform fee until 31 December 2026. You pay exactly the model's per-token rate — SuperbAPI adds nothing on top. After that date, any fee will be shown clearly before it applies.

No service fee

Every dollar becomes credit — plus a bonus.

Some AI aggregators take a service fee and tax before your money becomes credit. SuperbAPI charges no service fee and adds bonus credit instead.

Same models, one endpoint — and metering you can trust: every call shows its tokens, model, and exact cost in your usage feed, and failed calls are never charged. Third-party fees vary by provider and region.

How billing works

How you're charged

Prepaid credit, spent per call. You only pay for what you use — no monthly bill, no minimum, no surprises.

  1. 01

    Top up once

    Add credit at any amount. Bonus lands instantly and your balance stays valid for 12 months, across all 84 live models.

  2. 02

    Spend per call, per model

    Each request deducts that model's rate from your balance. The exact estimated cost is shown live in the workspace before you run.

  3. 03

    Failed calls are never charged

    If an upstream provider errors, you keep your credit. Pay only for calls that actually return a result.

What a call costsmetered from your credit
Text & reasoningBilled per token — input + output
Image, video & audioBilled per generated unit
Failed upstream callsNever charged
Optional US$20/mo planUnlimited keys + 10% off usage

You only ever spend your prepaid credit. No fixed monthly bill and no minimum — the optional subscription is the only recurring charge, and everything works without it.

Why SuperbAPI

One wallet, one endpoint, every model — and your keys stay yours.

Built so a single prepaid balance and a single base URL replace a drawer full of provider accounts, billing portals, and SDKs.

One endpoint for 84 models

Text, image, video, and audio from Google and Anthropic behind a single OpenAI-compatible route — switch models per request, never per integration.

One prepaid wallet

Top up once and spend across every model and modality. No per-provider invoices, no monthly minimum — your balance is the only thing that moves.

Scoped keys with limits & expiry

Issue a separate SuperbAPI key per app or per user, each with its own spend cap, model allowlist, and expiry date.

Your provider keys stay private

Your real Google and Anthropic keys live behind SuperbAPI and never reach your users' devices or your client code.

OpenAI-compatible drop-in

Keep the OpenAI SDK you already use. Change the base URL and key — your existing request and response shapes work unchanged.

Automatic provider fallback

When one upstream errors or rate-limits, SuperbAPI retries another automatically — and failed calls are never charged. Top up once and only pay for what you use.

Built for app makers

Give every user their own key — keep your provider keys private.

Issue scoped SuperbAPI keys to your users with per-key spend limits and model rules. Behind them, your real provider keys rotate automatically, so one failing upstream never takes your app down.
