ETH Block by Number
x402
ETH Block by Number is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-27).
Fetches a specific Ethereum mainnet block by block number (or 'latest') via eth_getBlockByNumber JSON-RPC.

How this service works
ARYSPHERE sells AI-written verdicts on Base token contracts (a grade, a one-liner, a roast and the contract's facts) and Base/Ethereum chain reads, paid per call in USDC on Base over x402 v2. No account and no API key.
Output
Returns the full Ethereum block object exactly as the node provides it via eth_getBlockByNumber JSON-RPC, including fields like block hash, parent hash, miner, timestamp, gas limit, gas used, transaction list, difficulty, and other standard block headers.
Example use cases
Inspect latest Ethereum block
“What does the latest Ethereum mainnet block look like right now? Grab all the details including transactions and timestamp.”
Audit specific block transactions
“Pull the full block data for Ethereum mainnet block 18900000 — I want to see all the transactions and gas info in it.”
Retrieve block timestamp for historical lookup
“I need the block data for Ethereum block number 17000000 so I can check its timestamp and who mined it.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/x402_chain_reads_v1/eth_getblockbynumber?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need full Ethereum mainnet block data by a specific block number or want the latest block. Prefer this over block-explorer scraping when you need raw, structured JSON-RPC output. Choose this over eth_blockNumber when you need more than just the block number — e.g., transactions, timestamp, miner, or gas data. Note this is for Ethereum mainnet; use sibling endpoints for Base chain block data.
Side effects
- Invalid block number format returns an error or null
- Block number not yet mined returns null
- Network/node unavailability causes timeout or 5xx error
- Malformed query parameter causes 400 bad request
- Payment not included or insufficient USDC results in 402 response
