Test mode
Test-mode API keys (b2b_test_) hit deterministic fake brand portals: same schemas and errors, zero portal traffic, never billed. Use them in CI and development.
Keys that start with b2b_test_ hit the fake portals our own test suite uses:
- one captured catalog per brand,
- deterministic availability,
- orders staged into a sandbox record with a fake portal URL.
Same schemas, same errors, zero portal traffic. Test calls are metered as surface=rest, env=test and excluded from billing views. Use test keys in CI, demos and while building an agent.
