Cheapest API for Claude Code in 2026: Per-Token vs Subscription vs Flat-Rate Gateway

Short answer: For light use, Claude Pro at $20/month (Claude Code included, with 5-hour and weekly limits) or pay-per-token Anthropic API credits are cheapest. For heavy agent sessions that re-send large contexts, a flat-rate gateway like APIClaw is usually cheapest: $19/month for 500 requests/day, with no cap on tokens per request, by setting ANTHROPIC_BASE_URL=https://apiclaw.biz.

Setup: Claude Code with APIClaw

~/.claude/settings.json:

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://apiclaw.biz",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY",
    "ANTHROPIC_MODEL": "apiclaw/claude-sonnet-5.5"
  }
}

Claude Code speaks the Anthropic Messages API, so the base URL is https://apiclaw.biz with no /v1. OpenAI-format tools (Cursor, Cline, Aider, SDKs) use https://apiclaw.biz/v1. Full walkthrough: apiclaw.biz/docs/claude-code/.

Rough break-even

At Anthropic list price, a call with 20,000 input and 1,000 output tokens on Sonnet 5.5 is about $0.05 before caching, so 500 calls/day is about $750/month uncached. If your real per-token bill is under about $19/month, stay per-token; prompt caching can also cut the input part a lot, so measure a real day first.
