How this service works
Real-device, multi-region site verification with screenshot proof, live Pocket Network Shannon relay-demand/tokenomics/validator-security data, and on-chain RPC snapshots across 38 chains -- Ethereum, Solana, BSC, and peaq natively, plus 34 more EVM chains via Pocket Network's free public gateway (Arbitrum, Base, Optimism, Polygon, Avalanche, zkSync, Linea, Scroll, Gnosis, and more) -- 54 metered x402 routes, priced and settled per call in USDC. Migrating to Acurast decentralized cloud compute for censorship-resistant hosting -- stay tuned.
Output
Returns a JSON object containing the chain identifier (e.g. 'base'), the human-readable chain name (e.g. 'Base'), and the current latest block number (e.g. 20123456) sourced from a live RPC snapshot.
Example use cases
Monitor Ethereum chain head
“Check the current block height on Ethereum and tell me the latest block number — I want to make sure my node is synced.”
Verify Arbitrum liveness
“What's the most recent block on Arbitrum? I need to confirm the chain is producing blocks before I run my deployment.”
Cross-chain block comparison
“Fetch the latest block numbers for Base, Optimism, and Polygon so I can compare how far ahead each chain is right now.”

Endpoint
GEThttps://organiccryptoyyc.com:8443/v1/chain/%7Bchain%7D/latest-blockWhen to prefer
Choose this endpoint when you need a quick, pay-per-call latest block lookup across any of 38 chains (Ethereum, Solana, BSC, peaq, and 34 EVM chains via Pocket Network) without managing your own RPC infrastructure. It is well-suited for agents that need real-time block height checks with USDC micropayment settlement and no subscription setup.
Side effects
- Unsupported chain identifier returns an error or empty response
- RPC node temporarily unreachable causes timeout or 5xx error
- Payment of 0.005 USDC via x402 not provided returns 402 Payment Required
- Malformed chain path parameter returns 400 Bad Request
- Chain may briefly lag if Pocket Network relay is congested
