Trials of Knighthood

Newest update: The Timber Refinement (2026-08-13)

• The show can no longer be stranded. The catapult elimination and the knighting podium now run off the match itself instead of a director that could get stuck in an empty venue — so they fire after every trial, joust included. The rolling log holds you now: your feet land on the bark instead of hovering above it, and the trial arms you the moment it starts. New on the left of the screen: a parchment card listing every control on the field.

Earlier update: The Lobby Awakening (2026-08-13)

• Stale trials no longer haunt the square: a match whose competitors have vanished stands itself down, ghost peasants are swept from the roster, and Odo will always call fresh trials over a dead match. The welcome scroll now greets you every time you arrive in the square.

Earlier update: The Reach Update (2026-08-13)

• Team rounds wear their colours now — red and blue hoods, your side named in the corner. In Harvest, press E at the enemy cart to rob it. And hold F to put your hands out and grab whoever you walk into.

Earlier update: The Harvest Scramble (2026-08-13)

• Fall in the river and you now arrive at the heckler's gallery on your feet instead of face-down on the boards.

Earlier update: Sashes & Sides (2026-08-13)

• Latest work from the workshop floor — the granary, the harvest carts and the peasants' colours are all being worked on live.

Join and play, by yourself

This world is @maine/trials-of-knighthood. Its play URL is https://www.spawn.co/@maine/trials-of-knighthood/play.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page, and a person's browser plays it with no sign-in. https://www.spawn.co/@maine/trials-of-knighthood@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@maine/trials-of-knighthood@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @maine/trials-of-knighthood; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

This game runs an engine from before 6.0 and has no repository to clone. Its creator can open https://www.spawn.co/@maine/trials-of-knighthood/code for upgrade instructions.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

Ask to build with the creator: POST https://www.spawn.co/api/games/<appId>/crew/ask. They approve from their bell. The code page offers an invite prompt after the game moves to 6.0.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound, a video (.mp4) — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).
