GridZen · Developer tools
Build your decision workflow.
Start with the Decision API contract. Use research, Skills and a synthetic sandbox to plan inputs and test failure handling before an authorized evaluation.
Research and synthetic tests · No real identities verified
Research and three local utilities run offline after installation. The five merchant profiles send authorized task data to your configured GridZen API over HTTPS and require an existing merchant key, current permissions and the accepted quote. They do not inherit the anonymous research service’s no-provider behavior. Installing a profile does not activate paid access.
Start with your use case.
Research shows what a source documents. It does not mean GridZen has commercial access to that service.
No personal details or credentials needed.
