concurrency-limit

Status	429
Title	Concurrency limit
Code	concurrency-limit
Type	https://docs.satellitedata.net/problems/concurrency-limit

Coming later This problem belongs to unit metering, which lean v1 does not have yet.

Meaning

The key already has as many requests in flight as its tier allows.

Likely causes

• More than 2 concurrent requests on the free tier, or 1 in restricted mode.

Fix

Wait for a request to finish before starting another, and keep your client’s concurrency at the tier limit.
