# Delx RRULE Daily Next Fire Times

> Delx RRULE Daily Next Fire Times is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Computes the next N fire timestamps for a daily recurring rule (RRULE) starting from a given unix timestamp with a configurable day interval.

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-rrule-daily-next-fire-times-8f3179dd -d '<json body>'
```

Example prompt: Starting from unix timestamp 1700000000, give me the next 7 fire times for a daily recurring rule that repeats every 2 days.

## When to prefer this

Choose this endpoint when you need to expand a simple daily recurrence rule into concrete unix timestamps for scheduling, queuing, or reminding — especially inside agent workflows that need to plan future task triggers programmatically. It is ideal when you already know your interval in days and want lightweight, deterministic timestamp expansion without a full calendar library.

## Known failure modes

- Missing required fields (n, from_ts, interval_days) returns validation error
- Non-integer or negative interval_days may produce unexpected results
- n=0 or very large n values may return empty or oversized arrays
- Invalid unix timestamp (negative or far-future) may cause computation errors
- Payment failure or insufficient USDC balance blocks execution

## How this service works

Next N daily fires from a DAILY RRULE-like interval. Call when expanding simple daily recurrences offline. Returns next_fire_unix list as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object with a schema identifier ('delx/util-rrule-daily-next/v1') and an array of unix timestamps representing the next N fire times for the specified daily recurrence rule.
