how it works

Point your tools here. Then keep shipping.

01point the base url

Set one base URL to https://obixhub.com and drop in a named obx_ key. Each SDK appends its own path — no plugin to install, no client fork to maintain.

02top up a balance

Add a prepaid balance in USD — $100, $300, $500, or any amount from $10. No monthly fee, no subscription, no minimum commitment.

03pay as you go

Every request draws down your balance at the official provider price — no markup. Unlimited concurrency, no rate limits, top up again anytime.

one base url

Every client. One base URL.

Point any client at the same origin to reach the Anthropic and OpenAI models through the official APIs — native endpoints, verbatim, no rewrite. Anything that speaks Anthropic Messages or OpenAI Chat/Responses just works.

why obixhub

Everything a small team needs from the Anthropic and OpenAI APIs.

one url, one key, two providers

Reach both the Anthropic and OpenAI APIs through a single base URL and a single obx_ key. Every client keeps its native wire format — verbatim passthrough, zero-rewrite drop-in.

prepaid, pay-as-you-go

Top up a balance and pay only for what you use, at the official provider price. No monthly fee, no subscription, no minimum, no lock-in.

no rate limits

No concurrency caps and no per-minute throttling. Fan out as many parallel requests as your workload needs; your balance is the only limit.

built on the official APIs

Anthropic and OpenAI models served through official Anthropic and OpenAI APIs — enterprise-grade stability, compliance, and data that is not retained.

your prompts stay yours

We never store prompts or completions. Only usage metadata — token counts, latency, model, status — is recorded; message bodies pass through and are gone.

team-ready

One shared balance, a named key per member, an owner-set model allowlist per key, and team usage in one dashboard.

pricing

Pay for what you use. Nothing more.

Top up a prepaid balance in USD, then every request draws it down at the official provider price. No monthly fee, no subscription, no minimum, no rate limits.

what you can count on
  • Prepaid pay-as-you-go — top up a balance and spend only what you use.
  • Transparent basis: usage is metered at the official provider price — no markup on what you use.
  • No rate limits and no concurrency caps — only your balance bounds you.
  • One team, one shared balance, a key per member — usage in one dashboard.
for the whole team

One balance. One key per member. One dashboard.

A team shares one prepaid balance. Every member gets their own named credential — and you see exactly where the spend goes.

shared balance

One top-up covers everyone. No per-seat fees and no juggling a separate account or invoice per provider.

managed in one place

Add members, give each their own named key and model allowlist, and manage everything from a single dashboard.

usage you can see

Track usage by member, model, and time — requests, tokens, and spend against the balance. Metadata only; never your prompts.

privacy posture

Your prompts never touch our storage.

We record only metadata — token counts, latency, model, and status. Never message bodies, never tool inputs. Your conversations pass through and are gone.

And because traffic runs through the official APIs, your prompts aren’t retained upstream either — not by us, not in the model serving path.

faq

Questions, answered.

What is obixhub?

An Anthropic + OpenAI API gateway for small teams, built on the official APIs. Point Claude Code, Codex CLI, or any compatible client at one base URL with one obx_ key and reach both the Anthropic and OpenAI APIs.

Which tools work?

Claude Code and Codex CLI are the reference clients. Claude Code uses the Anthropic Messages surface; Codex CLI uses the OpenAI Chat/Responses surfaces. Because we forward verbatim, any client that speaks one of those wire formats works the same way.

How am I billed?

Prepaid, pay-as-you-go. Top up a balance in USD — $100, $300, $500, or any amount from $10, with a flat 15% fee at top-up — and each request draws it down at the official provider price. No monthly fee, no subscription, no minimum commitment.

Are there rate limits?

No. There are no concurrency caps and no per-minute throttling — fan out as many parallel requests as your workload needs. Your balance is the only limit.

What runs the gateway?

Anthropic and OpenAI models are served through official Anthropic and OpenAI APIs — for enterprise-grade stability, compliance, and a serving path that does not retain your data.

Do you store my prompts?

No. We record only metadata — token counts, latency, model, and status. Message bodies and tool inputs pass through and are never written to our storage.

Can I switch models without changing code?

Yes. The same gateway reaches every curated Anthropic and OpenAI model — move between them by changing the model string.

Can my team share one balance?

Yes. A team shares one prepaid balance; every member gets their own named key and model allowlist, all managed from one dashboard.

What about large or enterprise volume?

Top up large amounts anytime, with no hard ceiling. For high volume or enterprise terms, contact us at sales@obixhub.com and we’ll set you up.
