Commercial decision

Pricing & plan limits

PlanPriceRequestsWhat's included
Free test tierFree—Per third-party directory; unverifiedsource

Low certainty. Official pages are JS shells (title only). Third-party directory gives conflicting paid pricing ($99/mo start vs $20-$1,000+ range) so no paid plan recorded. Protocols (graphql, rest) are guesses and not verified.

Before choosing a paid plan, confirm

• What counts as one request (per call, per market, per region?)

• What happens when you exceed the quota: blocked or billed

• Whether live and historical data are on your plan

• Whether your use (public app, betting, resale) is licensed

Preview brief
# Integration brief: Kalstrop

Goal: build a feature on Kalstrop data. Use only the official documentation below as the source of truth.

## Known facts (from SportDex, verify before relying on them)
- Website: https://www.kalstrop.com
- Docs: https://kalstrop.com/docs
- Sports: Multi-sport (40+)
- Data: Odds, Live scores, Team stats
- Protocols: GraphQL, REST; formats: json
- Auth: api_key
- Free plan: Free test tier
- Note: Low certainty. Official pages are JS shells (title only). Third-party directory gives conflicting paid pricing ($99/mo start vs $20-$1,000+ range) so no paid plan recorded. Protocols (graphql, rest) are guesses and not verified.

## Verify before writing code
- live update frequency
- whether commercial use is allowed on the plan you pick
- exact endpoint paths, parameters and response fields (read the official docs, do not guess)

## Implementation rules
- Keep the API key on the server (environment variable, backend route or edge function); never ship it to the browser.
- Cache responses and respect rate limits; count how many requests each screen triggers.
- Handle errors explicitly: invalid key, quota exceeded (429), missing fields, empty fixtures, timeouts.
- Start with one demo request and log the raw response before building UI on assumed field names.
