# Delx Floor N

> Delx Floor N is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Floors a numeric value to its nearest lower integer using a micropayment-gated API endpoint.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/floor-n
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-floor-n-14a5beb6
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HriEOK2h0BMLrk-Bz7YaK

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-floor-n-14a5beb6 -d '<json body>'
```

Example prompt: What's the floor of 7.83? Just give me the integer result rounded down.

## When to prefer this

Choose this endpoint when you need a deterministic, stateless floor operation in an agent pipeline that already uses x402 micropayments on Base and wants a lightweight, zero-setup math utility — particularly when you cannot or do not want to execute arbitrary code locally, or when standardizing numeric rounding behavior across distributed agents.

## Known failure modes

- Missing or non-numeric 'value' field returns a validation error
- Payment not completed or insufficient USDC balance results in a 402 Payment Required response
- Network timeout if the Base payment layer is slow to confirm
- Passing a non-finite value (NaN, Infinity) may cause an error or unexpected result

## How this service works

Floor a number to integer. Call when you need whole units from continuous values. Returns floored integer value for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns a JSON object containing the floored integer value of the input number — for example, 7.9 becomes 7 and -2.1 becomes -3. No additional metadata or state is stored.
