## 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-weekend-date-check-6d8e815e -d '<json body>'
```

Example prompt: Can you check if August 4, 2026 falls on a weekend?

## When to prefer this

Choose this endpoint when an agent needs a simple, stateless, first-party weekend check without importing a date library or maintaining calendar state. Ideal for serverless agents, lightweight pipelines, and routing logic where a deterministic JSON answer is needed and the $0.001 USDC per-call cost is acceptable. Prefer over custom code when you want auditability and consistency across heterogeneous agent runtimes.

## Known failure modes

- Invalid or missing date field returns a structured validation error (not billed)
- Malformed ISO-8601 string causes a parse error response
- Network timeout if the endpoint is temporarily unreachable
- Payment failure if the x402 USDC balance is insufficient

## How this service works

Weekend check for a date. Call when routing work, quiet hours, or business-day logic in agents. Returns whether the date falls on Saturday or Sunday. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

## Output

A deterministic JSON response indicating whether the supplied date is a weekend (Saturday or Sunday), enabling agents to branch on business-day versus weekend logic without any calendar library dependency.
