Clairvoyance – Unmasking Hidden GraphQL Schemas

Clairvoyance is a game-changer for GraphQL API developers. This tool gets the GraphQL API schema from sites where introspection is turned off and displays it in a user-friendly JSON format.

Learn how to install it, how to use it in more advanced ways, and how to get help from a dedicated team of contributors. You’ll also find out how to help out and deal with possible problems.

Some GraphQL APIs have disabled introspection. For example, Apollo Server disables introspection automatically if the NODE_ENV environment variable is set to production.

Clairvoyance helps obtain the GraphQL API schema even if introspection is disabled. It produces schema in JSON format suitable for other tools like GraphQL Voyager, InQL or graphql-path-enum.

Advanced Usage

Which wordlist should I use?

There are at least two approaches:

• Use general English words (e.g., google-10000-english).
• Create target-specific wordlist by extracting all valid GraphQL names from application HTTP traffic, from mobile application static files, etc. Regex for GraphQL’s name is [_A-Za-z][_0-9A-Za-z]*.

Environment variables

LOG_FMT=`%(asctime)s \t%(levelname)s\t| %(message)s` # A string format for logging.
LOG_DATEFMT=`%Y-%m-%d %H:%M:%S` # A string format for logging date.
LOG_LEVEL=`INFO` # A string level for logging.
