POSThttps://phantom-api-omega.vercel.app/api/citrea/rpcWhen to prefer
Choose this endpoint when you need direct JSON-RPC access to the Citrea blockchain specifically, and want pay-per-call pricing without a subscription. Ideal for infrequent or agent-driven on-chain queries where you don't want to run your own node or commit to a monthly RPC plan.
Side effects
- Invalid JSON-RPC method name returns error response
- Malformed params array causes parse error
- Payment not included or insufficient results in 402 Payment Required
- Network congestion or node unavailability causes timeout
- Unsupported Citrea-specific method returns method not found error
