What does Claude API actually cost?
If you're using Claude for development — especially Claude Code — you've probably noticed that Anthropic's native API pricing can add up fast. A single long context request with Opus can cost several dollars. Run Claude Code for a full workday and you're looking at $50–$200+ on raw API billing.
Anthropic offers two main paths for access:
Pay-as-you-go API — billed per token. Sonnet 4 runs around $3 per million input tokens and $15 per million output tokens. Fine for occasional use; expensive for heavy coding sessions.
Claude Max subscription — flat monthly fee with usage limits. Starts at $100/month, capped by daily usage windows. Good for moderate use, but you hit the ceiling quickly if you're running Claude Code all day.
Where resellers fit in
API resellers like Antex buy capacity in bulk at a negotiated rate and pass the savings to customers. Instead of paying token-by-token, you pay a flat monthly fee that covers a defined usage window.
The economics work because:
- Bulk purchasing lowers the per-unit cost
- Rolling usage windows (not per-day resets) smooth out spikes
- India-first pricing in INR eliminates forex fees for a large developer base
Antex pricing vs direct Anthropic
| Plan | Monthly | Equivalent to |
|---|---|---|
| Starter | $35 | Claude Max 5× |
| Pro | $70 | Claude Max 20× |
| Scale | $120 | 2× Claude Max 20× |
| Ultra | $200 | 4× Claude Max 20× |
The "equivalent" column isn't marketing — it's calculated from actual token capacity. The Pro plan at $70 gives you the same throughput as $1400/month of Claude Max usage.
What you get that direct access doesn't have
- Web search included — Claude Code's
web_searchtool works. Most resellers block it. - 1M context window — not artificially capped.
- Rolling windows — no midnight reset. Your 5h and 7d windows roll continuously.
- IP binding — your key is locked to your IP, protecting against theft.
- Zero prompt logging — nothing written to disk.
When direct API makes sense
If you need precise per-token billing for a production application serving many users, direct Anthropic API makes more sense. Resellers are optimized for individual developers and small teams with heavy, steady usage.
Bottom line
For solo developers and small teams using Claude Code daily, a reseller plan saves 60–80% compared to equivalent direct API usage. The break-even is around 2–3 hours of active Claude Code use per day.
