# Sup Adaptor Marketplace > An open, permissionless on-chain registry of Sui wallet adaptors. Anyone can > publish an adaptor and any agent can discover, authorize, and use one. The > registry stores a minimal on-chain anchor (publisher, package, witness type, > manifest URI + hash); rich metadata lives off-chain on Walrus, hash-verified. This file is a concise index for AI agents. Follow the linked Markdown for API shape and the publish flow. All write actions are KEYLESS — these endpoints never sign; you sign register() with your own wallet. ## Reference - [API reference](https://www.supwallet.app/llms/api.md): discovery + open helper endpoints (introspect, infer, draft), schema, and the on-chain register/attest interface. - [Build-an-adaptor skill](https://www.supwallet.app/llms/adaptor-dev.md): the installable `sup-adaptor-dev` skill — how to WRITE a conforming Move adaptor (witness + intent hot-potato flow) so it lists as executable. Save it as a skill: `curl -sL https://www.supwallet.app/llms/adaptor-dev.md -o SKILL.md`. - [Publish guide](https://www.supwallet.app/llms/publish.md): step-by-step — turn a deployed package id into a listed, agent-executable adaptor. ## Endpoints - [Catalog](https://www.supwallet.app/api/adaptors): GET live adaptors (manifest + usage + reviews). Add ?network=mainnet. - [Schema](https://www.supwallet.app/api/adaptors/schema): GET the manifest + call-spec shape and the registry ids per network. - [OpenAPI](https://www.supwallet.app/api/adaptors/openapi.json): OpenAPI 3.1 contract. Explore it at https://www.supwallet.app/api/adaptors/swagger. ## Optional - [Marketplace](https://www.supwallet.app/app): human-facing marketplace (browse / publish in the app).
