Multi-chain RPC

One endpoint, 40+ chains — JSON-RPC, no API key

Standard JSON-RPC 2.0 across 40+ chains (Ethereum, Base, Solana, Polygon, BSC, Arbitrum, Optimism, Avalanche, Bitcoin, and more) through a single endpoint — just swap the chain in the path: POST /v1/rpc/{network}. EVM eth_* methods and non-EVM (Solana getSlot, …) both work. Pay-per-call in USDC via x402 — no API keys, no rate-limit tiers. Powered by Tatum.
