Hey folks,

In a distributed microservices setup where multiple stateless services across multiple regions all depend on the same rate-limited third-party API, what’s a good way to throttle requests in a consistent and fault-tolerant way?

The catch is:

No centralized cache (like Redis)

No persistent storage

Gotta handle clock drift

Minimize cross-region latency

Still keep rate limits under control across all nodes

Anyone faced something like this? Would love to hear creative solutions or battle-tested approaches.

If the third-party API itself returns rate-limit headers, have each service node:

Parse X-RateLimit-Remaining, Retry-After, etc.

Back off locally based on that.

Not perfect, but helps each node self-throttle based on real feedback.
