## 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 x402-factory-science-tech-event-calendar-242eca38
```

Example prompt: Pull the science and tech prediction market calendar for the next 30 days — I want to see all upcoming events with their current resolution probabilities in date order.

## When to prefer this

Use this endpoint when you need a pre-filtered, date-ordered calendar of science and technology prediction market events with live probabilities in a single call, rather than fetching the full cross-category calendar and filtering client-side. Ideal for agents monitoring upcoming tech, AI, biotech, or space events and wanting to position around or report on them.

## Known failure modes

- Invalid days parameter (outside 1–90 range) returns a validation error
- Payment failure or missing x402 payment header results in a 402 response
- No events found for the requested window returns an empty events array
- Category mismatch or unsupported category enum value returns an error

## How this service works

Upcoming science and technology event resolutions — Upcoming science and technology market resolutions in date order with current blended probabilities — the forward calendar of science and technology events an agent can position around. Same shape as /v1/calendar, pre-filtered to science and technology markets.

## Output

A JSON array of upcoming science and technology prediction market events, each containing a slug, the market question, the resolution date, the current blended probability (0–1), and the category label, sorted in date order. A meta object accompanies the data payload.
