  Registry metadata endpoints (registry.npmjs.org/<pkg>, pypi.org/pypi/<pkg>/json), the GitHub account
  github.com/UltravioletaDAO (a User account with 13 public repos, not an Organization), and the provider's
  SDK docs at docs.execution.market/sdk/{python,typescript,plugin} and skill/reference/escrow.md.

  note: >-
    Execution Market's own client library, em-plugin-sdk (Python, httpx + Pydantic v2), is SOURCE-ONLY and the
    source is not reachable: docs/sdk/plugin says "not published to PyPI — install from the repository", and the
    repository it names (github.com/UltravioletaDAO/execution-market) returns 404 anonymously (the provider's own
    escrow reference says the monorepo "is private" and that a git-URL install "fails as an auth error or a 404").
    The two packages Ultravioleta DAO DOES publish are the uvd-x402-sdk payment SDKs (PyPI + npm), which carry the
    x402/EIP-3009 escrow primitives the API's money steps require and which the provider's own docs point agents
    at ("the published uvd-x402-sdk on PyPI carries the escrow primitives"). They are first-party to the company
    and load-bearing for calling this API, but they are payment-rail SDKs, not a typed client for the REST surface.
    Because >=1 official first-party package exists, an SDKs pointer is emitted; a consumer should read this note
    before assuming a typed Execution Market client is installable.
  open_source_claim: >-
    llms.txt, index.md, the MCP server card and the contributing page all describe the platform as open source
    (MIT/AGPL-3.0 are both named) and link github.com/UltravioletaDAO/execution-market; that repository was 404 on
    2026-09-19 (HTML page and REST API). Recorded as a documentation/reality gap, not as a package.

      Multi-chain x402 payment SDK (EVM, Solana, Stellar, NEAR). Same rail as the Python package; the TypeScript
      docs page for Execution Market shows raw fetch + @slicekit/erc8128 signing rather than this package.

      Typed async client organised as resource namespaces (tasks, submissions, workers, h2a, agents, escrow,
      disputes, worldid, reputation, evidence, payments, webhooks, identity). Not on PyPI (confirmed 404 at
      pypi.org/pypi/em-plugin-sdk/json) and the source repository is private, so version/published are null:
      checked, nothing installable to record.

third_party_packages:
  - language: typescript
    registry: npm
    name: '@slicekit/erc8128'
    official: false
    note: >-
      The request-signing library the provider's own TypeScript docs use for ERC-8128 (RFC 9421) signatures.
      Not published by Ultravioleta DAO; listed because the docs make it the de-facto client dependency.
