outplace developer resources

outplace is two public boards for Roblox games at outplace.lol: a land board of paid studs and a USD ranking board. There are no accounts. Identity is the Roblox place ID.

When to use this

Use the outplace API when you want to read the live land board, buy studs, read the ranking board, or start Stripe Checkout for a bid. Do not use it for Robux, Roblox.com ads, OAuth, or API keys.

Public free claims have ended. POST /api/claim returns HTTP 410. Legacy free plots were removed at the site relaunch.

Public API

Machine-verifiable index: GET /api. OpenAPI 3.1: /openapi.json. Errors return JSON with error, code, message, and hint.

• GET /api/plots — live land board
• POST /api/plots/checkout — buy studs (Stripe Checkout URL)
• GET /api/plot/session/<id> — plot status; deed once
• GET /api/board — live ranking board
• POST /api/checkout — bid (Stripe Checkout URL)
• GET /api/bid/<id> — paid bid status
• GET /go/<placeId> — 302 to Roblox

Auth

None. See /auth.md. A plot deed is a bearer secret for art on that one plot, not an API key.

MCP

POST /mcp (Streamable HTTP). Tools: get_plots, get_board. Server card: /.well-known/mcp/server-card.json.

Webhooks

Stripe sends checkout.session.completed to /api/stripe/webhook. That path is not a public agent endpoint. Listings and paid plots publish only after Stripe captures payment — never from session-create.
