The path to APV-100
Students and developers making their first real API integrations. Three courses, taken in order; finish one and its badge is yours, finish all three and the exam is waiting at the end.
- Course 2 of 3
Calling APIs from Code
Move from one-off requests to code you would ship: JavaScript and Python clients, retries, timeouts, secrets, caching and credit budgets.

Skills measured
Three skill areas, weighted equally
Each course is one skill area, 10 questions each, drawn fresh for every attempt.
API Foundations
33%- Make a real API request from the terminal, the browser and code
- Read a JSON response and pull out the field you need
- Authenticate with an API key, and keep that key out of public code
- Choose between GET and POST, and send parameters the right way
- Diagnose a failed call from its status code and error message

Calling APIs from Code
33%- Call an API with fetch in Node and the browser, and with requests in Python
- Add timeouts and retry with exponential backoff only when it is safe
- Keep API keys on the server with environment variables and a small proxy
- Cache responses so repeat lookups cost nothing
- Budget credits and stay under rate limits

What to expect
How exam APV-100 works
Two kinds of question
Most are multiple choice: a scenario, a snippet of code or a response, and four options. A few are hands-on: the exam shows you a request, you run it with your own key, and type the value from the response.
Hands-on answers are checked against your key
A hands-on answer counts only if your APIVerve key actually called that API. Running the call is the skill being measured.
Timed, open book
You have 45 minutes from the moment you start. The lessons and the docs are fair game, which is how you'll work on the job anyway.
A score report, pass or fail
Scores are out of 1000 and 700 passes. You'll see how you did in each course, so a near miss tells you exactly what to review.
Retakes
If you don't pass, you can retake the exam after 24 hours. After two attempts in a row without a pass, the next one opens after 7 days.
Your credential
Pass and you're issued a credential ID with a public verification page, one-click LinkedIn and a shareable transcript. Credentials don't expire.
Is the exam proctored?
No. It's an open-book online exam. The hands-on questions keep it honest: they're graded against calls your own key made.
Does it cost anything?
No. The courses, the exam and the credential are free, and the free plan's monthly credits cover the hands-on questions.
Do I need another certification first?
No. This is the starting point.
Can I change the name on my certificate?
You set the name when you start the exam. If it needs correcting after you've passed, contact us from the account that holds the credential.

Each one is its own three-course path and exam.
