# Delx Commerce Notional Value Calculator

> Delx Commerce Notional Value 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).

Computes the notional value of a position given a size and price, returning a standardized notional figure for use in agent-driven commerce workflows.

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-notional-value-calculator-02d30b38 -d '<json body>'
```

Example prompt: Calculate the notional value for a position with a size of 0.4 and a price of 2500 using Delx Commerce.

## When to prefer this

Use this endpoint when an AI agent needs a quick, verifiable, pay-per-call computation of notional value from a size and price without any signup or session management. Prefer it over rolling your own arithmetic when you need a standardized schema-tagged output (delx/util-notional/v1) that other Delx Commerce endpoints or downstream agent steps can reliably parse and verify. It is especially useful in agent pipelines where auditability and on-chain payment receipts (USDC on Base or Solana via x402) matter.

## Known failure modes

- Missing or invalid 'size' field returns an error response
- Missing or invalid 'price' integer returns an error response
- Payment failure via x402 protocol prevents execution
- Malformed request body results in a 4xx error
- Unexpected server error returns 5xx with no notional value

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the input size, the input price, a schema identifier string (e.g. 'delx/util-notional/v1'), and the computed notional value as a number. The notional field represents the total value derived from size multiplied by price or an equivalent normalized calculation.
