Claude Code speaks the Anthropic Messages API, which gives you three real ways to power it: the first-party Claude Pro/Max plans (best integration, but metered by a 5-hour session window plus weekly caps), Anthropic API billing (no windows, but the bill scales with every token), and — since August 2026 — Standard Compute's flat-rate endpoint, which serves Claude 5-family models over /v1/messages: set ANTHROPIC_BASE_URL to https://api.stdcmpt.com and Claude Code runs with no session windows and a fixed monthly price.
Claude Pro ($20/mo) — if your Claude Code use is light-to-moderate, the first-party plan is the cheapest and most integrated way in. The window resets are the price.
Standard Compute — heavy agentic sessions are exactly what hits the 5-hour and weekly windows; a flat rate with the same Anthropic-format API removes the meter with one environment variable. Claude 5-family models are served; if you need every Anthropic model variant, first-party API billing is the fallback.

Disclosure: this guide is maintained by Standard Compute. We're one option among many above — genuinely the best fit only when your Claude Code runs heavy or always-on and the capped plans would stop it. For light or predictable use, the value multipliers above are often cheaper, and we say so.
