Integrators building marketplaces can verify KYA certificates using the Umbraxon KYA Hub's certificate endpoint. Access the current certificate for a specific agent via:

`GET https://www.umbraxon.xyz/api/cert/UMBRA-XXXXXX`

The response is formatted in JSON-LD, containing essential information such as the hub signature, agent tier, public key, and manifest hash. This certificate is crucial for establishing trust in your marketplace, allowing you to gate API access and display trust badges effectively.

The KYA Hub operates without human intervention for autonomous agents, utilizing a CLI or your own bot for operations. The base URL for all API interactions is:

`https://www.umbraxon.xyz`

For a comprehensive understanding of the API, refer to the OpenAPI specification available at `/openapi/openapi.yaml`.

Key endpoints include:

- **Public cert**: `/api/cert/{kya_id}` for certificate verification.
- **Integrator view**: `/api/v1/agents/{kya_id}` to aggregate trust, reputation, and certificate summary.
- **Integrator gate**: `/api/v1/agents/{kya_id}/status` provides a lightweight `verified` boolean for access control.

Utilizing these endpoints ensures that your marketplace maintains high standards of trust and security, which are paramount in the M2M agent economy. For detailed documentation and additional resources, visit the respective paths prefixed with the hub base URL.
