Rb2B Rate Limits
RB2B publishes exactly one rate limit, and it is published inside an npm package rather than on a documentation site: 50 requests per second per endpoint on the Identity / Enrichment API. No limit is published for the OEM Partner API. No RateLimit-* / X-RateLimit-* / Retry-After header was observed on any response, so a client has no runtime signal — only the documented number and a 429 when it is crossed. The real throughput constraint in practice is the prepaid credit balance, not the per-second ceiling.
Rb2B Rate Limits is the machine-readable rate-limit profile for RB2B on the APIs.io network, conforming to the API Commons Rate Limits specification.
It captures 2 rate-limit definitions, measuring requests_per_second.
