Start a protein de novo design run
$ boltz-api protein:design start
POST/compute/v1/protein/design
Create a new design run that generates novel protein binder candidates
Parameters
--binder-specification: object { chain_selection, modality, structure, 2 more } or object { entities, modality, type, 2 more } or object { binder, type, rules }
Binder specification for protein design. Use no_template for sequence-defined binders, structure_template for uploaded binder structures, or boltz_curated for Boltz-managed nanobody and antibody defaults.
--num-proteins: number
Number of protein designs to generate. Must be between 10 and 1,000,000.
minimum10
maximum1000000
--target: object { chain_selection, structure, type } or object { entities, type, bonds, 3 more }
Target specification (structure template or template-free)
--idempotency-key: optional string
Client-provided key to prevent duplicate submissions on retries
maxLength255
--workspace-id: optional string
Target workspace ID (admin keys only; ignored for workspace keys)
