# Delx Commerce — Drawdown Percentage Calculator

> Delx Commerce — Drawdown Percentage Calculator 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).

Calculates the percentage drawdown between a peak and trough value, returning the drawdown_pct as a decimal-free integer.

## 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-drawdown-percentage-calculator-2c87643a -d '<json body>'
```

Example prompt: What's the drawdown percentage if the peak was 120 and the trough was 90?

## When to prefer this

Use this endpoint when you need a simple, verifiable, pay-per-call computation of drawdown percentage without setting up any account or subscription. Ideal for AI agents that need an auditable, on-chain payment trail (USDC on Base or Solana) for financial metric computations. Prefer over in-agent math when you need schema-versioned, verifiable results for downstream logging or compliance.

## Known failure modes

- Missing peak or trough field returns a validation error
- Non-integer values for peak or trough may cause a type error
- Peak value equal to zero could cause a division-by-zero error
- Trough greater than peak may return a negative or zero drawdown (undefined behavior)
- Payment failure over x402 protocol 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 containing the echoed peak and trough integers, the computed drawdown_pct as a percentage integer (e.g. 25 for a 25% drop), and a schema identifier string ('delx/util-drawdown-pct/v1') for verification purposes.
