Pricing
Free for up to 1M requests/month. Additional requests: $5/1M, charged to the team.
Authentication Methods
API Token
curl https://api.cartridge.gg/x/starknet/mainnet

-H "Content-Type: application/json"
-d '{
"jsonrpc": "2.0",
"method": "starknet_chainId",
"params": [],

}'
Domain Whitelisting
For browser apps, whitelist domains to make direct RPC calls without exposing tokens. Whitelisted domains are rate-limited per IP.
const response = await fetch('https://api.cartridge.gg/x/starknet/mainnet', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ jsonrpc: '2.0', method: 'starknet_chainId', params: [], id: 1, }), });
