Delx Commerce — Base Block Time Estimate
x402
Delx Commerce — Base Block Time Estimate is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Estimates the number of Base blockchain blocks that will elapse over a given duration in seconds, using a configurable assumed block time.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns an object with `estimated_blocks` (integer count of blocks for the given duration) and `assumed_block_seconds` (the block time used), along with a schema identifier, status, and evidence metadata confirming no data retention and zero external calls.
Example use cases
Preflight check for time-locked contract
“I'm deploying a time-locked smart contract on Base that should unlock after 10 minutes — how many blocks is that if we assume 2-second block times?”
Block window for on-chain voting period
“Our DAO vote needs to stay open for 3 days on Base. Can you estimate how many blocks that is, assuming each block takes 2 seconds?”
Scheduler calibration for agent transaction timing
“My agent needs to wait about 5 minutes before sending a follow-up transaction on Base. How many blocks should it wait if the assumed block time is 2 seconds?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/base-block-time-estimate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, verifiable, in-memory calculation to convert a wall-clock duration into an estimated Base blockchain block count — especially useful for EVM preflight checks, on-chain scheduling, and smart contract time-window planning. Prefer this over manual division when you need a structured, auditable result with evidence of no data retention.
Side effects
- Missing or invalid `duration_seconds` may result in a calculation error or unexpected zero result
- Non-numeric `assumed_block_seconds` will cause a schema validation failure
- Extremely large duration values may produce unexpectedly large block counts without bounds-checking
- Payment failure via x402 will result in a 402 response before computation occurs
