# Delx Timestamp Align

> Delx Timestamp Align is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Aligns an array of ISO-8601 timestamps down to fixed-width UTC interval buckets, returning deterministic bucket-aligned timestamps as JSON

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-timestamp-align-93b73f0b -d '<json body>'
```

Example prompt: Align these ISO-8601 timestamps to 300-second (5-minute) UTC buckets: ['2024-03-15T14:23:47Z', '2024-03-15T14:27:12Z', '2024-03-15T14:31:05Z'].

## When to prefer this

Choose this endpoint when you need pure, deterministic, stateless timestamp bucketing without any live data feed dependency. It is ideal for preprocessing caller-supplied tick data, event logs, or returns arrays before aggregation or signal computation. Prefer it over general-purpose time libraries when you need a cheap ($0.003), reliable, API-accessible transform callable by an agent without local code execution. It is not suitable for fetching live market data, computing derived signals, or any operation requiring external data sources.

## Known failure modes

- Invalid ISO-8601 format in any timestamp causes a validation error
- Non-positive or zero interval_seconds returns an error
- Missing required fields (timestamps array or interval_seconds) returns a 400-class error
- Non-UTC or ambiguous timezone offsets may produce unexpected bucket assignments
- Payment failure via x402 prevents execution and returns a 402 response

## How this service works

Align ISO-8601 timestamps down to fixed UTC interval buckets — call when bucket-aligning ISO timestamps to a UTC interval. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search…

## Output

Returns a deterministic JSON object containing each input timestamp mapped to its corresponding UTC bucket boundary (floored to the nearest interval), expressed as ISO-8601 strings. No upstream calls are made; computation is local and stateless.
