# Altss Public Machine Interfaces

> Read public metadata and contract descriptions; operational intelligence remains protected.

This specification documents public machine-readable website resources. It does not expose premium Altss intelligence, authenticated graph queries, bulk extraction, customer data, or automated paid-task execution. All listed GET operations return descriptions, catalogs or JSON Schema documents and require no authentication. Premium intelligence remains authenticated and permissioned in Altss; this specification declares no operational intelligence endpoint, API key, OAuth scope or machine authentication system. Website commercial form submission is deliberately excluded. Platform-level network, WAF and gateway errors are outside the application JSON error contract.

| Operation            | Public resource          | Purpose                             |
| -------------------- | ------------------------ | ----------------------------------- |
| getDataCatalog       | /data-catalog.json       | Read public field descriptions      |
| getTaskCatalog       | /task-catalog.json       | Read bounded task descriptions      |
| getCommercialCatalog | /commercial-catalog.json | Read public commercial descriptions |
| getPublicSchema      | /schemas/\{schema}       | Read a public JSON Schema document  |

[OpenAPI specification](https://altss.com/openapi.json)

These operations require no authentication because they return public descriptions only. Authenticated intelligence, search, records, graph queries, enrichment and task execution are not offered through this interface. The website commercial form is not a task-execution API.
