Api-Key · string · header · required

Body

application/json

Re-run a single block.

block_id is the block to run; run_id is the workflow run that supplied the original inputs. step_id optionally selects a specific step whose inputs should be used, which is useful for blocks inside a for_each loop.

run_id · string · required

Workflow run id that owns the step.

block_id · string · required

Workflow block id to execute.

step_id · string | null

Optional concrete step id whose inputs should be used. When omitted, the block id is used to look up the step.

n_consensus · integer | null

Optional override for n_consensus on extract / split / classifier blocks. Must be 3, 5, or 7.

check_eligibility · boolean · default: true

Whether to verify the upstream subgraph hasn't drifted since the source run. Disable only for explicit force-rerun flows.
