Cheaper Than the Official OpenAI API — Same Models, Up to 65% Off
Cut GPT API bills by 65% and Claude bills by 50% without changing models or code: one key, OpenAI-compatible and Anthropic protocols, per-token billing on list-price discounts.
What going direct buys you
The first-party APIs are the right home for features only the vendor can offer: fine-tuning on your data, org-level rate-limit negotiations, priority processing tiers, and direct vendor SLAs. Nothing here replaces those.
What direct billing does not give you is a discount. Small and mid-sized teams pay full list price per token — $5.00 per 1M input tokens on GPT-5.6 Sol, $3.00 on Claude Sonnet 4.6 — with separate accounts, keys, and invoices for each vendor.
What this API changes
The same upstream models are served at a fixed discount applied at billing: every GPT model at 65% off list, every Claude model at 50% off. One key calls both vendors, so cross-vendor fallback and A/B tests are a model-parameter change rather than a second integration.
Billing is strictly per token — no commitments, no seat fees, no minimum top-up tiers to justify. You can verify the discount on any request by comparing itemized usage logs against the official pricing pages.
The math on a real workload
A coding-agent load of 10M input + 2M output tokens per month on GPT-5.6 Sol costs $70.00 at list price ($5.00 in / $30.00 out per 1M) and $24.50 through this API. On Claude Sonnet 4.6, the same load is $60.00 at list and $30.00 here.
Both vendors' current list prices are on their pricing pages; the per-model pages on this site show every model's official-versus-discounted rate side by side.
Getting started
Create an account, generate a key, and point your existing OpenAI SDK at the base URL with the model id unchanged. Anthropic SDK users set the same host and keep the Messages API — prompts, tools, and caching behave the same.
If a feature genuinely needs the vendor account (fine-tunes, org-level limits), keep that slice direct and route the rest here — the two setups coexist without conflict.
FAQ
Are these the same models as the official APIs?
Yes — requests route to the same upstream GPT and Claude models. The discount is applied at this gateway's billing layer, not by substituting a different or quantized model.
Is this an official OpenAI or Anthropic service?
No. It is an independent API gateway that resells access to the vendors' models at a discounted rate. Vendor-exclusive features like fine-tuning are not available here.
What happens if I exceed my balance?
Top up when you need to; billing stays per-token with no contracts. Usage logs itemize every request so cost is auditable against list prices at any time.
