source: npm, PyPI, GitHub org search + B3 for Developers portal Swagger metadata
packages: []
notes: >-
  No first-party B3 client libraries were found on npm (no @b3 scope), PyPI
  (b3-api / b3-python / b3sdk all 404), or a public GitHub organization
  (b3-brasil and variants 404). The B3 for Developers portal (Axway API
  Manager) advertises generated SDK downloads per API - ios-swift, android,
  and nodejs (availableSDK in each harvested Swagger definition) - but these
  are portal-login-gated, contract-only downloads, not public registry
  packages. Access to B3 APIs is B2B under commercial contract, which is
  consistent with the absence of public SDKs.
