APIVerve Certified Architect: Solutions Architecture

• 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

• Choose between the hosted MCP server, your own MCP server and direct function calling for each agent, and isolate tenants with scoped keys
• Design tools at the right granularity, validate model-supplied arguments in code, and pass large outputs by reference
• Route consequential actions through approval queues and enforce policies and per-run credit and call budgets outside the model
• Contain prompt injection that arrives through tool outputs with taint tracking, quarantined extraction and least privilege
• Gate agent changes on replayed evals, trace every run, measure cost per outcome and run change control with clear ownership

Study: Architect Agent Platforms · 4 lessons

• Choose fail-open or fail-closed per feature and build fallback chains with circuit breakers and bulkheads
• Split one request's latency budget into per-dependency timeouts that cannot overrun it
• Size worker pools from rate limits and latency, and share one plan fairly across many tenants
• Minimise and redact personal data in requests, logs, caches and audit records
• Write and review an architecture document with SLOs, capacity, failure modes and decision records
