How this service works
Machine-readable settlement service
Output
Returns a JSON object containing machine-readable Nano blockchain chain information, including network identifiers, chain state, and related metadata. The response schema is open-ended and may include chain ID, genesis block, network version, or other chain-level parameters depending on the current Nano network state.
Example use cases
Nano network status check
“What are the current chain parameters and status for the Nano network? Pull the chain info so I can see the network identifiers and state.”
Cross-chain app configuration
“I'm building an app that needs to know the Nano chain's metadata — can you fetch the chain info so I have the right network details to configure my integration?”
Automated blockchain monitoring
“Every hour, fetch the Nano chain info from PennyRail and alert me if anything in the network metadata changes from what it was before.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/chain.info--chain-info?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need machine-readable Nano blockchain chain metadata in a programmatic, micropayment-gated context — particularly when integrating with x402-compatible payment flows or when you need lightweight per-call pricing at $0.001 USDC. Prefer this over general-purpose Nano RPC nodes when you want a hosted, discovery-friendly REST API rather than a raw node connection.
Side effects
- Missing or empty 'input' field returns validation error
- Invalid input string may return empty or null chain data
- Payment not fulfilled (x402) results in 402 Payment Required response
- Network or upstream Nano node unavailability may cause timeout or 503
- Malformed JSON body returns 400 Bad Request
