How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the input block count, the seconds-per-block value used, and the computed ETA in seconds (blocks × seconds_per_block), tagged with a schema identifier 'delx/util-block-time-eta/v1'.
Example use cases
Estimate DeFi lock expiry time
“My DeFi position unlocks in 200 blocks and the chain produces a new block every 13 seconds — how many seconds is that?”
Monitor NFT auction block deadline
“An NFT auction ends in 50 blocks and the average block time is 2 seconds — how long do I have left in seconds?”
Calculate cross-chain bridge confirmation wait
“The bridge needs 64 block confirmations and Ethereum's average block time is 12 seconds — tell me the ETA in seconds so I know how long to wait.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/block-time-eta?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a quick, cheap, stateless conversion from a block count to a wall-clock duration estimate and already knows the target chain's average block time. It is ideal for blockchain-aware agents that need to surface human-readable time estimates from on-chain block deltas without querying a node directly.
Side effects
- Missing required 'blocks' or 'seconds_per_block' fields returns a validation error
- Non-integer values for either field may cause a type error
- Zero or negative values for seconds_per_block may produce nonsensical or error results
- Payment failure via x402 protocol results in 402 response before computation occurs
