How this service works
Brazilian Jiu-Jitsu lineage lookup: trace any practitioner's instructor tree back through the Gracie and Maeda lineage to the source. Returns belt rank, academy, professors, and the full lineage chain. x402 pay-per-call on Base USDC. For gym directories, ranking systems, and AI agents verifying instructor credentials and martial-arts provenance.
Output
A structured response showing the practitioner's lineage chain, including instructor names, their instructors, and potentially belt levels or notable lineage milestones tracing back through the BJJ family tree.
Example use cases
Verify competitor lineage claim
“I just saw a BJJ competitor claim they're a Gracie lineage black belt — can you trace their full instructor chain and confirm how far back the Gracie connection actually goes?”
Research instructor relationships for profile
“I'm writing a profile on Marcelo Garcia and I want to include his full BJJ lineage — who trained him, who trained his instructor, and so on all the way back through the family tree.”
Compare lineage of two grapplers
“Can you pull up the BJJ lineage for both Roger Gracie and Andre Galvao? I want to see where their instructor chains overlap or diverge.”
