📄 Description

Summary

Adds automatic retry logic to the Brave Search integration when a 429 (Too Many Requests) response is received. This addresses the issue where Brave's free tier enforces a strict 1 request per second limit that can be hit even when concurrent requests is set to 1.

Problem

Setting WEB_SEARCH_CONCURRENT_REQUESTS to 1 prevents parallel requests, but does not add any delay between sequential requests. If your internet connection is fast enough, back-to-back requests can still exceed Brave's 1 request/second limit, resulting in 429 errors.

Solution

When the Brave API returns HTTP 429, the code now:

Logs a warning
Waits 1 second
Retries the request once
Proceeds with normal error handling if the retry also fails

This is a minimal, targeted fix that only affects Brave Search and respects the documented API rate limit without requiring additional configuration.

Fixes #15134
