rpc

# Multi-chain RPC — 40+ chains, one tool `blockrun_rpc` POSTs a standard JSON-RPC 2.0 body to `/v1/rpc/{network}`. Flat **$0.002 per call**; a JSON-RPC **batch array charges per element**. Settlement in USDC via x402. Responses are cached briefly server-side for identical read calls (`X-Cache: HIT` is free of upstream latency but still billed). ## When to use which tool | Question | Tool | |---|---| | "What's ETH trading at?" | `blockrun_price` (free) | | "PEPE/WETH pool liquidity?" | `blockrun_dex` (free) | | "What's this wallet labeled as / holding?" | `blockrun_surf` | | "Call `balanceOf(0x...)` on this ERC-20" | **`blockrun_rpc`** | | "Latest block / tx receipt / event logs / gas price" | **`blockrun_rpc`** | | "Solana account info / slot / signatures" | **`blockrun_rpc`** | ## Networks EVM (use `eth_*` methods): | Key | Chain | | Key | Chain | |---|---|---|---|---| | `ethereum` | Ethereum | | `zksync` | zkSync Era | | `base` | Base | | `berachain` | Berachain | | `arbitrum` | Arbitrum One | | `unichain` | Unichain | | `arbitrum-nova` | Arbitrum Nova | | `monad` | Monad | | `optimism` | Optimism | | `chiliz` | Chiliz | | `polygon` | Polygon | | `moonbeam` | Moonbeam | | `bsc` | BNB Smart Chain | | `aurora` | Aurora | | `avalanche` | Avalanche C-Chain | | `flare` | Flare | | `fantom` | Fantom | | `oasis` | Oasis Sapphire | | `cronos` | Cronos | | `kaia` | Kaia (Klaytn) | | `celo` | Celo | | `sonic` | Sonic | | `gnosis` | Gnosis | | `xdc` | XDC Network | | `abstract` ...
