DR-RatePacer
Adaptive HTTP rate control that delivers 100% success rates with zero throttle events against any production API.
What it is.
Most API client libraries handle throttling reactively — they catch the 429 and back off. DR-RatePacer paces forward, holding throughput just below the documented or inferred budget so the 429 never arrives.
No threshold tuning. No model fitting. No manual ramp schedules. Drop in as a one-line wrapper around requests, aiohttp, or fetch and the rate is paced against the discovered budget within the first seconds of traffic.
Benchmarked against GitHub-style, Shopify-style, and graph-style API archetypes with no observed throttle events and full request success.
What it does.
- 100% request success rate across benchmark archetypes; zero throttle events observed.
- Drop-in wrapper for requests / aiohttp (Python) and fetch (JavaScript).
- No tuning required — pacing target is discovered, not configured.
- Multi-tenant aware — coordinates across processes against a shared budget.
- No telemetry leakage — pacing decisions are local to the caller.
Who it is for.
Platform engineering teams, integration vendors, and growth-engineering groups that depend on third-party APIs where 429 storms or silent budget overruns translate directly into customer-visible outages.
