# Get Proof Page Metadata

> Returns metadata for a consumer content protection, used to render public proof pages. No authentication required.

Returns metadata for a consumer content protection record. Use this endpoint to render proof pages that show what was protected, when, and by whom — without requiring authentication.

This is a **public endpoint**. No API key or bearer token is needed. It is designed for proof page rendering and link previews (e.g. Open Graph metadata for shared proof URLs).

### Parameters

<ParamField path="attestation_id" type="uuid" required>
  The attestation ID linked to the consumer protection. This is the same ID returned in the `attestation_id` field of the [Protect Content](/api-reference/consumer/mint) response.
</ParamField>

info:
  title: Truthlocks API
  description: >
    Truthlocks is a universal verification infrastructure for documents,
    credentials, and digital assets.

    This specification defines the canonical API for interacting with Truthlocks
    services.


    ## Base URLs

    - **Production**: `https://api.truthlocks.com`

    - **Sandbox**: `https://sandbox-api.truthlocks.com`


    ## Authentication

    - **API Keys**: Use `X-API-Key` header for machine-to-machine operations

    - **Bearer Tokens**: Use `Authorization: Bearer <jwt>` for user-initiated
    operations


    ## Tenant Identity

    In production, tenant identity is derived from the authenticated context
    (API key or JWT).

    The `X-Tenant-ID` header is ignored in production to prevent spoofing.
