Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/unichain/rpcWhen to prefer
Choose this endpoint when you need fast, pay-per-call JSON-RPC access to the Unichain network without committing to a subscription. Ideal for agents that make sporadic or low-volume blockchain queries and want to avoid rate limits of free public RPCs. Prefer this over generic EVM RPC providers when the target chain is specifically Unichain.
Side effects
- Invalid or unsupported JSON-RPC method name returns an error response
- Malformed params array causes a parse or invalid params error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Network congestion or node unavailability causes timeout or 503
- Querying a block or transaction hash that does not exist returns null result
