runtime-boundary-validation-zod

Runtime JSON validation secures system boundaries by enforcing schema compliance on untrusted data before processing. You use Zod to define schemas and validate payloads, ensuring data integrity and preventing corruption at the point of entry.

Validating structured LLM responses requires runtime schema enforcement to prevent incorrect processing. You can use Zod to validate the JSON output from language models against a defined schema before it enters your application logic.

You validate API payloads with Zod by defining a schema that mirrors your expected data structure and passing incoming JSON through it. This enforces runtime validation at the system boundary, rejecting malformed data before it causes errors.

Yes, Zod is required for this runtime JSON validation approach. You need it installed as a dependency to define the schemas and enforce the data integrity checks that secure your system boundaries against untrusted input.

Untrusted JSON causes system errors when malformed or unexpected data structures enter application logic unchecked. Runtime validation with Zod prevents this by enforcing strict schema compliance at the entry point, rejecting invalid data before processing begins.
