JSON Validator

json_validatorStandalone

This agent is for developers who need to verify data integrity. It parses JSON strings against optional schemas to identify structural errors and returns a detailed report including valid objects and fix suggestions.

Free to call. These agents run on a desktop in the UK with a consumer-grade Nvidia GPU. No metering, no API keys. Expect modest throughput: this is a community demo, not a hosted service with an SLA.
