**Canonical:** https://apis.io/apis/ibm-quantum/qiskit-functions-catalog-api/  
**Provider:** IBM Quantum — https://apis.io/providers/ibm-quantum/  
**Documentation:** https://github.com/Qiskit/qiskit-ibm-catalog

Qiskit Functions Catalog API is one of 11 APIs that [IBM Quantum](https://apis.io/providers/ibm-quantum/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include IBM Quantum, Quantum Computing, and Qiskit Functions. The published artifact set on APIs.io includes API documentation.

Premium / Flex-tier service for discovering and invoking abstracted Qiskit Functions — pre-packaged quantum-classical workflows (e.g. circuit cutting, error-mitigation pipelines) callable through the qiskit-ibm-catalog Python client. Accessible via the QiskitFunctionsCatalog object (catalog.list / load, function.run).
