HTTP Status Codes
A searchable HTTP status reference for developers and API client authors: filter 1xx–5xx with color bands, find codes by symptom ("rate limit", "teapot"), see retryable/cacheable badges, common causes and plain-language next steps, RFC links, and one-line copy for tickets — including 418, 419, 499, and Cloudflare 520–526.
Runs 100% in your browser — nothing you paste leaves your device.

Notes
- Retryable / cacheable badges summarize what automated clients should do — not a substitute for Cache-Control headers on individual responses.
- 418 (RFC 2324) and 419 (Laravel CSRF) are real in the wild; 499 (nginx) and 520–526 (Cloudflare) are popular non-standard codes behind proxies.
- Runs 100% in your browser — nothing you paste leaves your device.
