Packages (SDKs & Backend)

[0.0.5] - 2025-10-28

Added

  • Backend Service:
    • The /lookup endpoint now returns the public_key for agents to enable cryptographic verification.
    • Implemented the /verify endpoint to allow for programmatic verification of agent claims.
  • JavaScript/TypeScript SDK (@ans-project/sdk-js):
    • Released version 0.0.5 to npm.
    • Added --policy-requirements flag to the anslookup CLI for advanced filtering.
    • The lookup method now includes the agent's public_key in the response.
  • Tests & Demonstrations:
    • Added Test 00008 for programmatic verification using the /verify endpoint.
    • Added Test 00009 for a visual demonstration of the end-to-end verification workflow.
  • Documentation:
    • Added agent-verification-workflow.md explaining the cryptographic principles and workflow.
    • Added backend-api-testing-strategy.md detailing the backend testing strategy.

Fixed

  • Backend Service: The /lookup endpoint now correctly parses policy_requirements when sent as a stringified JSON.
  • JavaScript/TypeScript SDK (@ans-project/sdk-js):
    • Fixed a bug in the anslookup CLI argument parser to correctly handle values.
    • Corrected the conversion of kebab-case arguments to snake_case for the backend API.
