}'On the Pro plan ($19 lifetime), Claude Opus 4.5 is $1.00 per 1M input tokens and $5.00 per 1M output tokens. That's 80% off the official price ($5/$25). The Basic plan is free forever at 70% off.
Yes. The proxy forwards requests to the same underlying model with the same context window (200k tokens) and capabilities. Only vendor-fingerprint headers are stripped. Behavior, output quality, and reasoning are identical.
Change one line — the base URL — in your existing Anthropic or OpenAI SDK initialization. Use https://claudeapi.cheap/api/proxy for Anthropic-format calls or https://claudeapi.cheap/api/proxy/v1 for OpenAI-format. Use your sk-cc-... key as the API key. No code changes beyond that.
Pro plan caps at 500 requests/min and 2M tokens/min globally across all models. Basic plan is 200 RPM / 1M TPM. Newer models may have lower upstream caps that float — see /status for live availability.
Yes. Streaming, tool/function calling, and prompt caching all work end-to-end. Vision is supported where the upstream model supports it.
