How this service works
Classify a chess time control (bullet, blitz, rapid, classical) from base minutes and increment, with estimated length.
Output
Returns the time control category (bullet, blitz, rapid, or classical), standard notation string, estimated seconds per player, estimated total game minutes for both players, maximum game minutes if all time is used, along with the echoed base minutes and increment seconds, plus optional summary, verdict, reasons, and source/disclaimer fields.
Example use cases
Classifying a tournament time control
“I'm organizing a chess tournament with a 10-minute base time and a 5-second increment per move — what category does that fall under, blitz or rapid, and what's the estimated game length?”
Labeling a bullet game format
“Someone challenged me to a 1+0 chess game — is that bullet, and can you give me the standard notation and estimated playing time?”
Verifying classical game length estimate
“I want to know if a 90+30 chess game qualifies as classical and roughly how many minutes it would take for both players to finish if all time is used.”

Endpoint
GEThttps://chess-notation.x402tookit.com/time-control?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically classify a chess time control into its standard category (bullet/blitz/rapid/classical) and get an estimated game duration from raw clock parameters. Prefer it over manual lookup tables when building chess apps, tournament managers, or game-analysis tools that need to label or filter games by time control type.
Side effects
- Missing required baseMinutes parameter returns an error
- Non-numeric or negative baseMinutes value may cause a validation error
- Very large or unusual values may return degraded or uncategorized results
- Network or payment authorization failure prevents response
