It proxies standard JSON-RPC calls to QuickNode's node infrastructure across a wide range of blockchains and networks including Ethereum, Solana, Bitcoin, Arbitrum, Base, Polygon, Avalanche, BSC, Optimism, Cosmos, Celestia, Near, Sui, Aptos, and many more — over 80 chains with both mainnet and testnet coverage.\n\nTwo payment intents are supported: \"charge\" (one-shot payment per call at $0.001) and \"session\" (payment channel at $0.00001 per call). Payment can be settled via Tempo (PathUSD or USDC.e on Tempo Testnet or Mainnet) or via Solana (USDC on Solana Mainnet, charge intent only). The endpoint URL pattern is `https://mpp.quicknode.com/session/{network}` for session-based calls or `https://mpp.quicknode.com/{network}` for charge-based calls. No API key or account signup is required — authentication is handled entirely through MPP micropayment credentials attached to each request.\n\nThe OpenAPI spec defines a full schema for every supported network. Tempo testnet wallets have a 10,000 lifetime request cap per intent. The request body is a standard JSON-RPC 2.0 payload (method, params, id). Responses include a Payment-Receipt header with the settlement transaction hash or channel ID.","tags":["rpc","json-rpc","evm","solana","tempo","node"],"capabilities":["json-rpc-proxy","multi-chain-rpc","pay-per-call","session-payment-channel","mpp-tempo-settlement","mpp-solana-settlement","no-api-key","blockchain-node-access"],"categories":["blockchain","rpc"],"synonyms":["quicknode rpc","blockchain rpc api","pay per call rpc","multichain node api","ethereum rpc","solana rpc","json-rpc proxy","web3 rpc endpoint","mpp rpc","quicknode mpp"],"warnings":["Probe returned 404 because HEAD/GET were tried on a POST-only parameterized path; the endpoint is live per the OpenAPI spec and root 200 response.","Tempo testnet wallets have a 10,000 lifetime request cap per intent.","Session intent does not support Solana USDC settlement — only Tempo methods are available for sessions.","Crawled pages (/docs, /api, /pricing, /README) all returned 'unsupported_network' — no external documentation was retrievable."],"endpointUrl":"https://mpp.quicknode.com/session/:network","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"quicknode.com","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.880","qualityRationale":"Full OpenAPI 3.1 schema with detailed x-payment-info for every network, clear pricing, request/response examples, and well-defined 402/403 behavior.
