API Rate Limit and Abuse Protection Designer
Design API rate limits, quotas, abuse detection, throttling, fairness, retries, and client-facing limit contracts.
API Rate Limit and Abuse Protection Designer is a free AI skill for api & integration building. Design API rate limits, quotas, abuse detection, throttling, fairness, retries, and client-facing limit contracts. It works with Claude, ChatGPT, Cursor and is ready to use out of the box.
About this skill
API Rate Limit and Abuse Protection Designer helps teams protect public and internal APIs from overload, scraping, brute force, accidental loops, and unfair consumption. It defines identities, dimensions, algorithms, quotas, burst handling, retries, headers, monitoring, and escalation.
What it does
The skill analyzes endpoints, users, plans, traffic, cost, abuse patterns, and reliability requirements; selects rate-limit algorithms and enforcement points; defines quotas and exemptions; adds observability and client guidance; and produces implementation and test specifications.
What is included
- Traffic and abuse model
- Limit dimensions
- Algorithm selection
- Quota and burst rules
- Client response contract
- Monitoring and alerting
- Exception and escalation rules
- Test and rollout plan
How to use it
1. Download the api-rate-limit-and-abuse-protection-designer-SKILL.md file 2. Upload it to your API or platform workspace 3. Provide endpoints, users, traffic patterns, plans, and known abuse 4. Add latency, availability, and commercial constraints 5. Use the design to implement and verify protection
Examples
Design rate limiting for a public AI API with free, pro, and enterprise plans, expensive analysis jobs, login endpoints, and webhook callbacks.
A complete policy with identity keys, token bucket and concurrency limits, endpoint classes, plan quotas, headers, retry behavior, login protections, job limits, monitoring, exceptions, and tests.
