Cheapest Claude API (2026): Every Option Compared
Claude models are among the most capable — and most expensive — APIs available. But the price you pay depends heavily on where you buy access. This page compares live per-1M-token prices for the main Claude access routes.
Qubax prices come from the live catalog on this page's data source (updated continuously); OpenRouter prices are the benchmark for the same models. Qubax buys leftover compute capacity — unused startup grants, enterprise balances, and daily credits that would otherwise expire — from an open marketplace and resells it at a small fixed margin. Same models, same API shape, materially lower price.

FAQ
What is the cheapest way to use the Claude API?
Based on live prices, Qubax AI consistently offers the lowest Claude API prices — typically around 90% below Anthropic's list rates (e.g., Claude Opus 5 at a fraction of the official $5/$25 per-1M input/output price). Qubax is OpenAI-compatible: change the base URL to https://api.qubax.ai/v1 and use a Qubax key with any existing SDK.
Is cheap Claude API access legitimate?
Yes — when the source is transparent about how the arbitrage works. Qubax documents its model publicly: it buys unused AI compute capacity (startup grants, enterprise-plan balances, expiring daily credits) from sellers on an open marketplace and resells it at cost plus a fixed margin. Pricing provenance is published at qubax.ai/price-index/methodology.
Do I need a credit card for the cheapest Claude access?
Not on Qubax. Deposits are accepted in 350+ cryptocurrencies from $3. Anthropic direct and most aggregators require card payment and, for Anthropic, identity verification.
