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 eta_seconds (estimated seconds until required confirmations are reached) and remaining_confirmations (how many more confirmations are needed), along with verifiable evidence metadata including a SHA-256 hash of the input, confirmation that no data is retained, and zero external calls made.
Example use cases
Pre-trade confirmation readiness check
“Before I execute the next step of my DeFi trade, tell me how long until my pending Base transaction gets to 15 confirmations — it currently has 6 and blocks are about 2 seconds each.”
Bridge transfer timing estimate
“I'm bridging tokens from Base and the bridge requires 20 confirmations. My tx has 5 so far and blocks average 2 seconds — how many seconds until it's ready to claim on the other side?”
Agent pipeline ETA gating
“My on-chain settlement transaction needs 10 confirmations before I can release the funds, and it currently has 4. With 2-second blocks, what's the estimated wait time remaining?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/base-confirmation-eta?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use, no-signup calculation of Base blockchain confirmation ETA with verifiable, privacy-preserving execution (no data retained, hash-evidenced). Ideal for AI agents orchestrating on-chain workflows that need to gate next steps on transaction finality without building custom block-polling logic.
Side effects
- Missing required fields (current_confirmations, required_confirmations) returns an error
- Negative or invalid values for confirmations may produce undefined behavior
- Payment failure via x402 protocol results in 402 response before computation
- If current_confirmations >= required_confirmations, ETA may return 0 or an edge-case result
