Pay only for what you use. Per-token chat is billed at provider cost — no platform margin.
Pricing Formula
Your cost = Provider cost (per-token chat — no margin, matches OpenRouter)
+ $0.001 / request (flat x402 transaction fee)
Media generation and Live Search still carry a 5% platform margin, which covers:
x402 settlement infrastructure
Smart routing and reliability
No API key management
Instant on-chain payments

Free Tier (8 models)
The free tier is 10 reasoning, coding, and vision models with no per-token
charge. The lineup is kept current by a self-healing health gate that routes
around any model whose upstream is temporarily unavailable and auto-recovers
it, so existing calls keep working. All free-tier models are FREE for both
input and output — call GET /api/v1/models for the current live list.
