Estimates only; official vendor pricing prevails (2026-10-30). Model cost = in÷1M×rate + out÷1M×rate; adjusted total = model cost × (1 + credit fee). Fee is charged when buying credits (Standard 5.5% / Business 8%), not per request. Curated presets only — not the full catalog; BYOK omitted.Official pricing: OpenRouter pricing · models

How it works

How is the credit fee applied?
OpenRouter charges a fee when you buy credits (Standard 5.5%, Business 8%), not as a markup on each API request. Adjusted total ≈ token cost × (1 + fee). BYOK billing is omitted.
Why only ~12 models?
v1 ships a curated popular preset list so rates stay maintainable. The full 500+ catalog is on openrouter.ai/models — paste custom $/1M into the rate fields if needed.
Are results invoices?
No. Estimates only; openrouter.ai/pricing and live model rates prevail.
Is any data uploaded?
No. These calculators and QR codes run in your browser.
Can these AI prices change?
Yes. Vendors change list prices often. Edit the $/1M or plan fields, and confirm on the official pricing page before you budget.
