# Delx Commerce — Base Confirmation ETA Calculator

> Delx Commerce — Base Confirmation ETA Calculator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Calculates the estimated time remaining (in seconds) for a Base blockchain transaction to reach the required number of confirmations given current confirmation progress.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-base-confirmation-eta-calculator-e30a04fc -d '<json body>'
```

Example prompt: My transaction on Base currently has 3 confirmations and needs 12 total — assuming 2-second block times, how many seconds until it's fully confirmed?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
