API engineering specialist team — 5 agents (api-design-architect, api-implementation-engineer, api-security-engineer, api-testing-engineer, api-platform-engineer) for the full lifecycle of an API you produce: paradigm choice (REST/GraphQL/gRPC/webhooks/AsyncAPI), contract-first design (OpenAPI 3.1/3.2, AsyncAPI 3.0, Arazzo), versioning & deprecation; the build craft (RFC 9457 Problem Details, cursor pagination, Idempotency-Key, ETag concurrency, HTTP semantics, 202+polling, RateLimit headers); security (OWASP API Security Top 10 2023 — BOLA/BOPLA/BFLA, token/scope validation, consumption limits, SSRF); and testing & operations (contract tests, Spectral lint in CI, Prism/Postman mocks, k6 load, gateway design, dev portal + SDK codegen, sunset rollout). Knowledge bank with 10 Mermaid decision trees + a dated 2026 capability map, 22 best-practices, 6 templates, 6 commands, 1 advisory hook.
