Synthetic test environment
SYMBaiEX API sandbox
Test client parsing, discovery, search requests, and error handling against deterministic synthetic fixtures. This environment never reads production data, creates accounts, sends webhooks, invokes a model, or performs writes.
Read-only operations
Fixture boundary
Every returned identifier starts with sandbox-. The endpoint accepts no bearer token, idempotency key, mutation, job, upload, or destination URL. Use the authenticated production API only after owner-approved enrollment.
