| 1 | # Quicknode Blockchain Infrastructure |
| 2 | |
| 3 | ## Intake Questions |
| 4 | - Which chain and network should Quicknode target? |
| 5 | - Is this read-only or should I create infrastructure (streams, webhooks, IPFS writes)? |
| 6 | - Does this require real-time streaming (Solana gRPC/Blazar WSS/HyperCore gRPC) or standard RPC? |
| 7 | - What endpoint or API key should I use (default: `QUICKNODE_RPC_URL`, optional `QUICKNODE_WSS_URL` / `QUICKNODE_API_KEY`)? |
| 8 | - If no API key exists, does the agent want pay-per-request access (x402, MPP) or a wallet-paid Quicknode account via [Agent Subscriptions](#agent-subscriptions)? |
| 9 | - Any constraints (latency, regions, throughput, destinations)? |
| 10 | |
| 11 | ## Safety Defaults |
| 12 | - Default to testnet/devnet when a network is not specified. |
| 13 | - Prefer read-only operations and dry runs before creating resources. |
| 14 | - Never ask for or accept private keys or secret keys. |
| 15 | |
| 16 | ## Confirm Before Write |
| 17 | - Require explicit confirmation before creating or modifying Streams, Webhooks, or IPFS uploads. |
| 18 | - Require explicit confirmation before creating an Agent Subscription, topping up credits, or any action that spends real funds via x402 or MPP. |
| 19 | - If confirmation is missing, return the exact API payload for review. |
