Sending 40 Rows From Make to the Claude API Stops at Row 14 — Avoiding the 429 With One Subtraction

Why a no-code automation that sends spreadsheet rows to the Claude API one by one hits a 429 partway through, and how to fix it. Seven spacing strategies tested on a mock bucket, a formula for the Sleep delay, and settings that stop failed rows from vanishing.

A 429 With retry-after: 120 Makes the Anthropic SDK Try to Wait 120 Seconds

I ran the Anthropic SDK's automatic retries against a mock server in 12 scenarios. Two retries by default, retry-after obeyed with no cap, and spend-limit 429s that no amount of waiting fixes. Code for a retry wrapper with a wait cap and a time budget, plus the logs.

When Claude API Suddenly Starts Returning 429 in Production — Field Notes on Measuring Rate-Limit Headroom from Headers and Throttling Before You Run Dry

Scrambling to add retries after a 429 is always a step behind. Claude API writes how much you have left into every response header. These are field notes on measuring that headroom continuously and throttling yourself before it runs out.

How to Fix Claude API 429, 503 Errors and Timeouts: A Complete Troubleshooting Guide

Struggling with Claude API 429 rate limit errors, 503 service unavailable responses, or timeout failures? This guide covers root causes and step-by-step fixes including exponential backoff, concurrency control, and Tier upgrades.

Claude API 429 Errors in Production: Lessons from Six Parallel Content Pipelines

When Claude API starts returning 429 Too Many Requests, the official exponential-backoff snippet alone is rarely enough. Drawing on six content pipelines run by one indie developer, this guide covers the real failure modes I have observed, working Python and TypeScript retry implementations with jitter, a token-bucket throttle, and concrete criteria for moving jobs to the Batch API.
