# Delx Commerce — Ceiling (Ceil-N) Math Utility

> Delx Commerce — Ceiling (Ceil-N) Math Utility is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Returns the ceiling (rounded-up integer) of a given numeric value via a pay-per-call API using USDC micropayments.

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-ceiling-ceil-n-math-utility-91078660 -d '<json body>'
```

Example prompt: What is the ceiling of 3.7? Round it up to the nearest integer.

## When to prefer this

Use this endpoint when your AI agent needs a lightweight, no-signup ceiling math operation billed per call via USDC micropayments on Base or Solana — ideal for agent pipelines that need verifiable, pay-as-you-go arithmetic without embedding a math library or managing subscriptions.

## Known failure modes

- Missing or non-numeric 'value' field returns a validation error
- Non-finite inputs (NaN, Infinity) may return an error or unexpected result
- Payment failure (insufficient USDC balance) results in HTTP 402 and no computation
- Network timeout returns no result

## 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 containing the ceiling (rounded-up integer) of the input value, plus a schema identifier string ('delx/util-ceil-n/v1') confirming the response format.
