How this service works
Pay-per-call endpoints for AI agents: web search, web-to-markdown reader, LLM chat completions, encrypted secret storage with one-read dead drops, and a business-idea generator. Payment over x402: USDC on Base, or XNO on nano:mainnet.
Output
Returns a JSON object containing the latest block number for the requested EVM chain (Base, Polygon, Arbitrum, or Optimism), representing the most recently mined block at the time of the request.
Example use cases
Block confirmation depth check
“I need to know the current block number on Arbitrum so I can calculate how many confirmations my transaction has received.”
Chain liveness monitoring
“Can you check the latest block number on Optimism and tell me if the chain is still actively producing blocks?”
Cross-chain block height comparison
“What are the current block heights on Base and Polygon? I want to compare how fast each chain is producing blocks.”
Technical details
Endpoint
GEThttps://pyfile-agent.taile3ff35.ts.net/data/chain/block-number?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call lookup of the current block number on Base, Polygon, Arbitrum, or Optimism without managing your own RPC node. Ideal for agents that need occasional block height checks rather than continuous streaming, and when you want L2-focused coverage across the four most popular EVM L2/sidechain networks.
Side effects
- Unsupported chain name returns an error or empty response
- Network connectivity issues to the RPC node may cause timeouts
- Chain parameter missing or misspelled may return an error
- Rate limiting or payment failure (x402) blocks the request
