Run MedQA on Benchlist
Benchlist runs the canonical MedQA sample set, captures every transcript, builds a Merkle commitment, and signs the result with an Ed25519 attestor key. The score lands at a public verify URL anyone can replay, and you can opt into an Aligned Layer ZK anchor on Ethereum L1.
Hosted runner, POST a job and we email the verify URL when it's done:
curl -X POST https://benchlist.ai/api/v1/run \
