# Delx Commerce — Time Series Gap Scanner

> Delx Commerce — Time Series Gap Scanner is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).

Scans an array of timestamps for gaps larger than an expected interval, returning each gap's start, end, and duration in seconds

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-time-series-gap-scanner-d2b47729 -d '<json body>'
```

Example prompt: I have this list of hourly sensor timestamps and I want to know if there are any gaps longer than 3600 seconds — can you scan them and tell me exactly where the missing windows are?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call check for temporal gaps in a list of timestamps without standing up your own time-series validation logic. Ideal for agents doing data-quality checks, pipeline audits, or sensor monitoring where signup friction and recurring subscriptions are undesirable.

## Known failure modes

- Missing or empty timestamps array returns an error or empty result
- Non-ISO-8601 or unparseable timestamp strings cause parsing failures
- expected_seconds of zero or negative may produce undefined behavior
- Very large timestamp arrays may cause truncated=true in the response
- Network or payment failure results in no response

## 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 a list of detected gaps (each with 'after', 'before', and 'seconds' fields), the total gap count, the count of valid timestamps processed, the expected interval used, a schema identifier, and a 'truncated' boolean indicating if the result was capped.
