# Delx Commerce — RRULE Daily Next Fire Times

> Delx Commerce — RRULE Daily Next Fire Times 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).

Computes the next N daily recurrence fire timestamps starting from a given Unix timestamp, using 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-commerce-rrule-daily-next-fire-times-c082bfa9 -d '<json body>'
```

Example prompt: Starting from now (Unix timestamp 1700000000), give me the next 5 fire times for a daily recurring rule that repeats every 2 days.

## When to prefer this

Use this endpoint when an AI agent needs to deterministically compute future recurrence timestamps for a daily repeating rule without standing up a full calendar or cron service. Ideal for lightweight scheduling, preview of upcoming event times, or agent-driven automation planning where RRULE-based daily intervals are needed at sub-cent cost.

## Known failure modes

- Missing required fields (n, from_ts, interval_days) result in a validation error
- Invalid or negative interval_days may produce unexpected results
- n set to 0 or negative may return an empty array or error
- Non-integer values for any field cause schema validation failure
- Payment failure via x402 prevents the call from completing

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object with schema 'delx/util-rrule-daily-next/v1' containing an array of Unix timestamps representing the next N scheduled fire times for a daily recurring rule, computed from the provided start time and interval.
