mirrored listing x402 eip155:8453eip155:137eip155:42161

LLM inference at a flat $1

LLM inference at a flat $1.00 per call, with no account, no API key and no token metering. POST a prompt, get the completion: the same price for 10 tokens or 4000, while metered gateways scale with usage. Automatic failover across several large models; typical response under 1s. Pay per call in USDC over x402 - nothing to sign up for.
