# Delx Abs N

> Delx Abs N is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns the absolute value of a signed numeric input, stripping the sign to yield the magnitude.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/abs-n
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-abs-n-c4c12887
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_dCi_MVTnQ1ltG2UQjfCn8

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-abs-n-c4c12887 -d '<json body>'
```

Example prompt: What is the absolute value of -47.83?

## When to prefer this

Choose this endpoint when your agent pipeline needs a lightweight, pay-per-call absolute-value computation without bundling a math library, especially in environments where you want a simple deterministic JSON response for signed deltas, balances, or differences. It is ideal for low-overhead microcomputation steps inside larger agentic workflows.

## Known failure modes

- Missing or null 'value' field returns a validation error
- Non-numeric input (e.g. string) causes a type error
- Payment failure via x402 results in a 402 response before computation occurs

## How this service works

Absolute value of a number. Call when you need magnitude from signed deltas or balances. Returns absolute numeric 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

A JSON object containing the absolute (non-negative) numeric value of the input, computed locally without any external network calls or data retention.
