soulbound.tools Community tools & open game data

Tools for Soulbound: Online

The community home for anything built on Soulbound: Online's game data — planners, item databases, comparison sheets, Discord bots, whatever you want to make.

The data comes from Spiderware, the studio that makes the game, as a free read-only API. No signup, no permission to ask for. Build something good and we will list it here.

The directory

What people have built

Every listing is opened and checked by a person before it appears. How to submit.

Build your own

One API, no signup

Everything the planner knows about items, abilities, relics, followers and stats, at api.soulbound.tools. The full reference — every route, every field, every error — lives at /docs. 

# five legendary chest pieces
curl "https://api.soulbound.tools/v1/items?slot=chest&rarity=legendary&limit=5"
{
  "data": [
    {
      "id": "…",
      "name": "…",
      "slot": "chest",
      "rarity": 4,
      "rarityName": "legendary",
      "stats": [ { "stat": "power", "value": 17 } ]
    }
  ],
  "meta": { "total": …, "count": 5, "cursor": "…" }
}

Shape, not real values. GET and HEAD only — there is no write path in the Worker at all. CORS is open, so browser tools work.

  • The reference

    Every route and response field, a worked example, and the errors table.

  • Point an AI agent at it

    An OpenAPI spec and an llms.txt your agent can read on its own.

  • Ask for a key

    Only if 60 requests a minute is not enough. Anonymous access keeps working either way.

AI agents

Built to be read by a machine

Read-only, one error shape, cursor pagination and a published OpenAPI document — which happens to be exactly what an agent needs.

There is nothing to install and no connector to configure. Point whatever you are building at the spec and it can work out the rest.

Agent setup guide →

One thing to tell your agent. Drop rates, loot-table weights and anything else describing how likely an item is to drop are not published, and will not be. An agent that goes looking for them will burn its budget on requests that cannot succeed. The docs page has a system prompt you can paste that says so.

About the data

What is in it, and what is not

What is published

Items including cosmetics, abilities, relics, followers, the stat vocabulary and the artwork. Item entries carry their stats, their roll ranges, legendary effects and requirements.

What is not

Drop rates, loot-table weights and anything else describing how likely an item is to drop. That is a deliberate line rather than an oversight, and it is not going to move.

How it updates

We publish by hand when we choose to, so the API is not a live mirror of the game and can lag a patch. Every response carries x-dataset-version, and /v1/meta has the version, the publish date and the record counts.

Licence & usage

The game art, assets and data are © Webb Technology Limited (trading as SpiderWare); Soulbound: Online is a trademark. You are welcome to build tools on them under our usage terms — see the Fan Content and Third-Party Extensions policies there. Building something commercial? Ask us first.

Submit a tool

Post it in Discord

Reviewed by a person, then added by hand.

Send us the link and we will look at it. If it works and it is what it says it is, we will add it. There is no form on this page on purpose: a directory of links is exactly where someone would try to plant a fake build planner, so nothing appears here that a human has not opened first.

What to send

  • The name and the link
  • Who made it, and how you want to be credited
  • One line describing what it does
  • Two or three tags
  • A screenshot, if you have one

Post it in Discord

What we check

  • It loads, and it does what the description says
  • It does not ask anyone for their Soulbound account details
  • It does not present itself as official when it is not
  • It is not a copy of one of our sites wearing a different domain

For players. No tool listed here will ever ask you to log in with your Soulbound account. If one does, it is not ours. Close it and tell us, and we will pull the listing.

We can remove a listing at any time, usually because the tool stopped working or moved. Being listed is not an endorsement of anything beyond the check above, and these tools are made by their authors, not by us.
