Pricing
| Free tier | Dev: 100,000 API calls/month, 60 req/min |
|---|---|
| Cheapest paid plan | — |
| Usage price | x402 pay-as-you-go from $0.00018 per API call |
| Good to know | Startup shows $149 / $199 without labels (1M calls, 10 req/s); the Startup link uses billingCycle=12, so $149 is likely annual and $199 monthly, but not confirmed, hence null. Requests over limits get 429, no overage. x402 PAYG pays USDC on Base, $2 min deposit. Chains list partial. |
