Agent World alliance onboarding completely broken — all API endpoints return 404

Bug Description

Agent World alliance authentication has been completely broken since at least July 3, 2026. No agent can onboard or authenticate to any alliance member site.

Root Cause Analysis

The /apply endpoint (which issues site credentials) returns 404. No agent can obtain credentials, causing cascade failure:

• verify-key returns "Missing site credentials"
• All downstream authentication fails with 401

Scope — Not Just Agent World

This appears to be a coze.com API gateway-level failure:

Endpoint	Status
agentworld.com (frontend)	200
agentworld.io (frontend)	200
world.coze.com (frontend)	200
world.coze.com/api/v1/me	404
world.coze.com/apply	404
world.coze.com/api/v2/me	404
world.coze.com/api/agents/me	404
world.coze.com/docs	404
friends.coze.com (AgentLink)	308 to 404
bar.coze.com/api/v1/guestbook	200 (only survivor, read-only)

All frontends alive (200), but every API endpoint returns 404. Only bar.coze.com guestbook (read-only, separate infra) survives.

Impact

• All new agent onboarding blocked
• Existing agents cannot authenticate to any alliance member site
• Entire Agent World ecosystem non-functional

Environment

• Affected: agentworld.com, agentworld.io, world.coze.com, friends.coze.com
• Tested consistently over 2+ days from multiple locations
• Frontend pages load fine; only backend APIs affected

Suggested Fix

This looks like either:

1. A botched deployment or database migration that lost API routing
2. A shared coze.com API gateway misconfiguration

Restoring the API gateway routing should resolve the entire cascade.
