## 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-boolean-not-e62f1390 -d '<json body>'
```

Example prompt: Can you flip the boolean value 'true' to its opposite using the Delx boolean NOT utility?

## When to prefer this

Choose this endpoint when you need a verifiable, pay-per-result boolean NOT computation via a blockchain-settled micropayment (USDC on Base or Solana via x402), and require no API signup or account. Prefer it in autonomous agent pipelines that need auditable, on-chain-settled utility computations.

## Known failure modes

- Missing or non-boolean 'value' field in request body returns an error
- Passing a non-boolean type (string, number, null) may cause a validation error
- Payment failure or insufficient USDC balance prevents call execution
- Network timeout or service unavailability

## 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 inverted boolean value (e.g. {"value": false, "schema": "delx/util-bool-not/v1"}), where the output value is the logical negation of the input boolean.
