PRIMORDIA

Newest update: The Vault Ascends (2026-07-25)

• The spawn gate marketplace now lives in your hands — unlock and trade ancient gate styles as you discover them.
• Gates now face you when placed, no longer spawning twisted backward into the earth.
• The showcase finds you anywhere in the world, even when you're standing in distant places.
• World gates sync instantly across all connected realms, no matter where you are.

Earlier update: The Spawn Gates Update (2026-07-25)

• Worlds you add now stay exactly as you entered them—no automatic refreshing or renaming.
• The showcase now displays your newest worlds first, so fresh discoveries aren't buried by old links.
• A critical boot-race bug that sometimes duplicated worlds on room restart has been fixed.
• World covers and images now persist correctly across sessions.

Earlier update: The Gateway Update (2026-07-24)

• Spawn gates now reliably preserve their visual state and appearance across world saves and loads.
• Portal veil materials and lighting effects stay consistent when you revisit worlds with active gates.
• Gate spawning behavior has been refined so portals appear at the correct scale and visibility from the moment they manifest.
• The world registry and showcase system now handles world URLs properly, letting you add and revisit worlds without losing your place.
• Curated world showcase drawers let hosts hand-pick featured worlds for visitors to discover.

Earlier update: The Showcase Update (2026-07-23)

• A curated showcase of worlds now appears alongside your traveler's registry — handpicked destinations chosen by world hosts.
• World hosts can now claim ownership of their showcase entry and curate which worlds appear in the featured collection.
• The showcase respects view-mode variants, share tokens, and path differences — no more duplicate world rows cluttering your list.
• God-mode users can claim their world's showcase entry to take control of how it appears in the collection.

Earlier update: The Spawngate Update (2026-07-23)

• Walk through mystical portals to visit worlds crafted by other players.
• Unlock premium gate styles—from gothic archways to sci-fi airlocks—with spoins.
• Your worlds appear as destinations in the shared gate network, discoverable by anyone.
• Gates stay alive as long as players keep walking through them; unused portals fade away.
• A browser extension lets you jump to linked worlds with a single click.

Join and play, by yourself

This world is @badgerblunts/primordia. Its play URL is https://www.spawn.co/@badgerblunts/primordia.

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 that any browser plays, headless included, with no sign-in. https://www.spawn.co/@badgerblunts/primordia@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.

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 @badgerblunts/primordia; 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

With build access, clone https://git.spawn.co/@badgerblunts/primordia.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

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.

The door in: the creator copies one prompt at https://www.spawn.co/@badgerblunts/primordia/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @badgerblunts/primordia in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

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).

Build, test, and share

Publish when the game is ready for players. Share its play link so friends can join.
