Idempotency
Idempotency is the property of an operation that produces the same result whether it is executed once or multiple times. In AI automation systems, idempotent API calls and message handlers ensure that retries after network failures or timeouts do not cause duplicate actions — duplicate payments, duplicate records, or duplicate AI-triggered workflows.
Idempotency is implemented through idempotency keys: unique identifiers sent with each API request that the server uses to deduplicate retries. For AI agents operating in agentic loops with tool calls that modify state (write to database, send email, initiate payment), non-idempotent operations are a production reliability risk. Design tool calls to be idempotent by default; use idempotency keys for external API calls.

- API Rate Limiting — API rate limiting is the enforcement of maximum request rates on an API — typically measured in requests per minute, tokens per minute, or requests per day — to protect the provider's infrastructure and ensure fair allocation among customers.
- Workflow Automation — Workflow automation is the replacement of repetitive multi-step business processes with software that executes them deterministically, with optional human checkpoints at decision points.
- AI Agent — An AI agent is a software system that takes a goal, plans a sequence of steps to reach it, executes those steps using tools (APIs, databases, browsers, code), and adapts when steps fail.
