Delx Base Block By Hash
x402
Delx Base Block By Hash is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Fetches a Base blockchain block header by its hash using eth_getBlockByHash via a pay-per-call x402 API.

How this service works
Base block header by hash for $0.001 USDC via eth_getBlockByHash. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns the block header fields for the specified Base chain block hash, including block number, timestamp, parent hash, miner/coinbase address, gas limit, gas used, transactions root, state root, receipts root, difficulty, and extra data — equivalent to the eth_getBlockByHash JSON-RPC response.
Example use cases
Verify block timestamp for a transaction
“I have a Base chain block hash 0xabc123... — can you fetch that block and tell me exactly when it was mined and what block number it is?”
Inspect block gas details on Base
“Pull up the Base block with hash 0xdeadbeef... and show me the gas limit, gas used, and miner address for that block.”
Trace parent chain linkage
“Given Base block hash 0x987fed..., can you retrieve its block header so I can see the parent hash and verify the chain linkage?”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-block-hashWhen to prefer
Choose this endpoint when you need to look up a specific Base L2 block by its exact hash — for example, to verify block metadata, confirm timestamps, or trace chain linkage. Prefer this over a block-by-number lookup when you have the hash but not the number. It is ideal for agents that need lightweight, pay-per-call blockchain data access without managing their own RPC node or API key for Base.
Side effects
- Invalid or malformed block hash returns an error or null result
- Block hash not found on Base network returns null
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
- Network timeout if Base RPC node is temporarily unavailable
- Passing an Ethereum mainnet hash instead of a Base chain hash may return null
