flatkey — Every official model. One key. Half the price.

FREE START · 全场最慷慨

$2 credit + 3 runs before signup

Together and Segmind killed their free tiers; Novita is down to $0.50. flatkey still lets you run real models before you even sign in.

SMART ROUTING · 会自己调度的 KEY

flatkey-auto, no routing fee

One model name; the gateway picks the best official model per request — task-aware, health-aware, always the lowest multiplier that meets quality.

TRUST · 官方直连,零量化

Official APIs, audited hourly

No fp8 re-serves, no silent swaps. Every model probed against its official fingerprint, on a public log — 163/163 verified, 30-day streak.

PAY LOCAL · 本币支付

Pix, UPI, Alipay — your currency

Prices in BRL, INR or CNY at checkout, 3DS-secured. Plus Anthropic-shaped API: point Claude Code or Cline at one base_url and go.

Claude at half price.
Everyone else charges list.

Together, Novita and Segmind don’t carry official Claude at all. flatkey: 60–90% of list on every model, top-up bonus stacks to an effective 50%.

TRUST · 模型真实性,逐小时探针验证

0 model swaps. Ever.
And we prove it.

Every hour, every model is probed against its official API fingerprint — logits, tokenizer, refusal shape. The log is public. Cheap gateways ask for trust; flatkey shows receipts.
