Policies

Sandbox vs production
Use sandbox credentials for integration testing; production credentials carry FCRA-permissible-use attestations and stricter audit logging.
Backoff
On 429 / 503, apply exponential backoff with jitter; do not retry idempotent reads aggressively as inquiries can post to the consumer's bureau record.
Inquiry minimization
Cache permissible-use results where regulation allows to minimize repeated bureau pulls against the same consumer.
