Dragon Ball API — free mock REST API for testing

Explore Dragon Ball fighters and transformations, then run authenticated tournament battles with deterministic sandbox results.

The Dragon Ball API tracks fighters, their transformations and the power levels those transformations produce, plus tournaments that seed brackets from them. Power level is derived rather than stored, which makes it a compact target for testing a client against computed fields it must not try to write.

What you can practise here

• Transform a fighter and confirm the power level the API computes rather than the one you sent.
• Enter the same fighter into a tournament twice and read the conflict.
• Submit a transformation the fighter has not unlocked and check the 422.
• Seed a bracket with an odd number of fighters and see how the API resolves it.
