# Delx Min N

> Delx Min 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 minimum value and count from a numeric list supplied by the caller

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-min-n-c491f32b -d '<json body>'
```

Example prompt: Find the minimum value in this list of numbers for me: [42, 7, 99, 3, 55, 18] — just return the min and how many values there were.

## When to prefer this

Use this endpoint when an agent needs a fast, stateless minimum computation over a numeric list without building or shipping its own math logic. Ideal for pipelines where the list is already in memory and a floor value is needed as a decision input — e.g. budget floors, latency thresholds, or score minimums. It pairs naturally with other Delx aggregation primitives.

## Known failure modes

- Empty array input — may return an error or undefined minimum
- Non-numeric values in the array — likely causes a validation error
- Malformed request body — returns a 4xx error
- Payment failure via x402 — call is rejected before processing

## How this service works

Minimum of a numeric list. Call when you find floors across agent-held samples. Returns min value and count 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 the minimum numeric value found in the input array along with the count of elements that were evaluated. No data is retained after the call.
