## 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 f1-circuits-by-season-f01be724 -d '<json body>'
```

Example prompt: Can you give me a list of all the Formula 1 circuits used in the 2023 season, with their names, cities, and countries?

## When to prefer this

Use this endpoint when you need structured F1 circuit data (circuit ID, name, locality, country) for a specific season year, especially when building race calendars, analyzing historical race geography, or enriching F1 standings data with venue information. Prefer this over general sports APIs when you specifically need Jolpica/Ergast-compatible circuit identifiers.

## Known failure modes

- Invalid or non-existent season year returns empty results or error
- Missing query parameter may return all circuits or an error
- Season years outside F1 history (pre-1950 or future) may return no data
- Network or upstream Jolpica/Ergast API unavailability causes failure
- Payment failure (x402) returns 402 status before data is delivered

## How this service works

Jolpica/Ergast F1 circuits used in a season year: id, circuit name, locality and country Query: ?q= Returns JSON.

## Output

A JSON array of F1 circuits for the specified season year, each entry containing the circuit ID, circuit name, locality (city), and country where the circuit is located.
