Compose API Systems
Design systems that use many APIs: choose providers with evidence, run calls as a dependency graph, enrich records with provenance, and decide what to build yourself.

What you'll be able to do
- Evaluate competing APIs with a live proof of concept and a weighted decision matrix
- Model a multi-API workflow as a dependency graph and run independent steps concurrently
- Separate required from optional steps so partial failures return useful results
- Run idempotent enrichment stages that store provenance and re-enrich stale data
- Compare total cost of ownership and record the decision as an architecture decision record
This course is one of three skill areas on exam APV-400, APIVerve Certified Architect: Solutions Architecture: 10 of its 30 questions. See the full path
Syllabus
- Choose the right APIs for the jobStart hereEvaluate APIs on schema fit, data coverage, freshness, credits, latency, premium fields and failure modes, then prove the choice with live calls and a matrix.
- Orchestrate multi-API workflowsModel a multi-API workflow as a dependency graph, run independent calls concurrently, split a latency budget, and merge partial failures into one result.
- Design enrichment pipelinesEnrich records through several APIs with queued, idempotent stages, store provenance with every fact, catch schema drift, and re-enrich stale data.
- Build versus buy for API capabilitiesCompare the total cost of building a capability with buying it as an API, spot when building wins, plan a hybrid path, and record it as an ADR.
