Zircuit

by NodeFlare in Onchain & crypto

x402 APIPassing, checked 2 h ago

Zircuit RPC (chain 48900): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units. One of the first independent x402 RPC providers for this chain.
