Effort: Low · OCTOBER 11, 2026

Saves £20/month vs fixed subscriptions

Claude 3.5 Haiku is priced at $0.10/M input and $0.50/M output on OpenRouter with zero markup. A $20 deposit provides ~200M input tokens (~40,000 conversations).

Why youYou recently compared Muse vs OpenRouter costs; this provides instant, pay-as-you-go access to Claude without a recurring $20/month subscription.

OpenRouter acts as a unified API gateway for foundation language models, providing direct pass-through pricing with zero recurring membership fees. Anthropic's Claude 3.5 Haiku is priced at $0.10 per million input tokens and $0.50 per million output tokens, while Claude 3.5 Sonnet is priced at $3.00/M input and $15.00/M output.

Instead of paying a rigid $20 monthly subscription fee for Claude Pro—which expires regardless of usage—a single $20 prepaid balance on OpenRouter provides enough compute to process approximately 40,000 queries on Haiku or 1,500 substantial coding prompts on Sonnet with zero recurring commitment.

OpenRouter accepts standard debit cards, cryptocurrency, and credits without requiring complex enterprise billing agreements or phone number verifications.
