Getting Started with API v2

The RBLXValue API gives you direct access to our full Murder Mystery 2 value database — the same data that powers rblxvalue.com. Version 2 lives on its own subdomain and adds value history, a meta endpoint, and richer item data.

Base URL​

https://api.rblxvalue.com/v2

Coming from v1? See What's New in v2. The old rblxvalue.com/api/v1 API keeps working — see the v1 (legacy) docs.

Step 1 — Get an API key​

All data endpoints require an API key. Create one for free with your Roblox account at rblxvalue.com/developer.

Step 2 — Make your first request​

curl "https://api.rblxvalue.com/v2/items/corrupt" \
  -H "X-Api-Key: your_key_here"

You can look items up by slug or acronym, case-insensitive — corrupt, Corrupt and CORR all resolve to the same item.

Step 3 — Read the response​

{
  "item": {
    "id": 16,
    "name": "Corrupt",
    "slug": "corrupt",
    "acronym": "CORR",
    "value": 338,
    "value_source_a": 325,
    "value_source_b": 350,
    "category": "unique",
    "type": "Knife",
    "tier": 9,
    "stability": "Stable",
    "demand": 3,
    "rarity": 3,
    "range": "N/A",
    "event_name": null,
    "description": "Corrupt is a unique knife in Murder Mystery 2...",
    "image_url": "https://cdn.un6107617.dev/rblxvalue/items/Corrupt_Transparent.webp",
    "fandom_url": "https://murder-mystery-2.fandom.com/wiki/Corrupt",
    "last_updated": "2026-09-05 05:51:53"
  },
  "credit": null
}

value_source_a is MM2Values, value_source_b is Supreme Values, and value is the blended estimate. Values are refreshed every 12 hours.
