Endigest AI Core Summary
Cloudflare now returns RFC 9457-compliant structured Markdown and JSON error responses to AI agents, replacing HTML error pages and reducing token usage by over 98%.
•AI agents previously received HTML error pages (46,645 bytes / 14,252 tokens) designed for humans, making it impossible to determine error type or retry strategy.
•Cloudflare now detects Accept headers (text/markdown, application/json, application/problem+json) and returns compact structured payloads instead.
•The structured response includes machine-readable fields: error_code, error_category, retryable, retry_after, and owner_action_required for deterministic agent control flow.
•Markdown responses are 64.5x more token-efficient (221 tokens) and JSON responses are 55.7x more efficient (256 tokens) compared to HTML.
•
This is network-wide and automatic — no site owner configuration required; browsers continue receiving HTML responses unchanged.
