Multi-chain RPC

JSON-RPC 2.0 passthrough across 40 chains (powered by Tatum). Swap `ethereum` in the path for any network — base, solana, polygon, bsc, arbitrum, optimism, avalanche, bitcoin, sui, and more: POST /api/v1/rpc/{network}. One endpoint, every chain, no API key. $0.003 per call; a JSON-RPC batch is priced per element.0.003 USDThe operation requires declared authentication; API keys, bearer tokens and other schemes are not evidence of AEP support.
