Observed with no token, a placeholder (not real) `Bot` token, and a bare placeholder `Bearer`. No real Discord credential was used or held. ## Observed | Probe | Status | Body | `x-discord-features` | |---|---|---|---| | `GET /users/@me` (no token) | **401** | `{"message": "401: Unauthorized", "code": 0}` | `user-profile` | | `GET /users/@me` with `Authorization: Bot PLACEHOLDER.NOT.REAL` (placeholder) | **401** | identical: `{"message": "401: Unauthorized", "code": 0}` | `user-profile` | | `GET /users/@me` with `Authorization: Bearer PLACEHOLDER` (placeholder) | **401** | identical | `user-profile` | | `GET /gateway/bot` (no token) | **401** | identical | `bots` | | `GET /nonexistent-route` | **404** | `{"message": "404: Not Found", "code": 0}` | `unknown` | | `GET /invites/zzzz-not-a-real-invite-zzzz` | **404** | `{"message": "Unknown Invite", "code": 10006}` | `invites` | | `GET /gateway` (no token) | **200** | `{"url":"wss://gateway.discord.gg"}` (`cf-cache-status: HIT`, `last-modified` present) | `sessions` | | `GET /invites/discord-developers` (no token) | **200** | full invite object incl. `guild.id`, `guild.features[]` | `invites` | | `GET /sticker-packs` (no token) | **200** | `{"sticker_packs":[...]}` | `stickers` | ## What an agent gets wrong 1. **`code` is not a status code and is usually 0.** Missing token, bad token, and unknown route all return `code: 0`; the JSON `code` only becomes informative for Discord domain errors (here `10006` Unknown Invite). Branch on the HTTP status first, then on `code` only when it is non-zero. 2. **No-token and bad-token are indistinguishable** — same 401, same body, byte for byte. You cannot tell "I forgot the header" from "my token is revoked" from the response. 3. **The body is not compact JSON** — `{"message": "401: Unauthorized", "code": 0}` has spaces after the colons and commas; a naive byte-equality check against a compact fixture fails. 4. **No `X-RateLimit-*` headers were present on any anonymous response**, including the 200s above. The bucket/limit/remaining/reset headers that Discord documents for authenticated routes were **not observed** here, and nothing about 429 bodies (`retry_after`) is asserted; no 429 was triggered. 5. `x-discord-features` names the internal feature that served the route (`user-profile`, `bots`, `invites`, `sessions`, `stickers`, `unknown` for an unrouted path) — a handy debugging breadcrumb. Every response: `server: cloudflare`, `content-type: application/json`, `x-content-type-options: nosniff`, and a `content-security-policy` with Sentry report endpoints. ## Reproduce ``` curl -s -D - https://discord.com/api/v10/users/@me # HTTP/2 401 ... {"message": "401: Unauthorized", "code": 0} curl -s https://discord.com/api/v10/invites/zzzz-not-a-real-invite-zzzz # {"message": "Unknown Invite", "code": 10006} curl -s https://discord.com/api/v10/gateway # {"url":"wss://gateway.discord.gg"} ``` How observed: 2026-09-30 UTC, direct HTTPS with curl (UA `nh-batch10-saas-probe/1.0`), nine probes above with `-D -`.
