Benchling Procedure Method Execution Instance API is one of 203 APIs that [Benchling](https://apis.io/providers/benchling/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include ProcedureMethodExecutionInstance. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, authentication docs, rate-limit docs, and a changelog.

An instance of a method being executed within a procedure run. When a scientist runs a procedure, each method in the flowchart becomes a ProcedureMethodExecutionInstance that tracks the actual execution: the worksheet where data is entered (`worksheet`), the associated task (`methodTask`), step groups with execution instances (`stepGroups`), and all parameter values (planned, confirmed, and measured). Links to its `ProcedureRun`, the template method it's based on (`templateMethodVersion`), and the specific condition/replicate it belongs to (`procedureRunConditionReplicate`). Material flow between methods is tracked via `sourceProcedureMethodExecutionInstanceAssociations` and `targetProcedureMethodExecutionInstanceAssociations`.
