What are the core components of the OPP standard?

The three core components of OPP are the Standardized Provider Manifest (`/.well-known/opp.json`) for data declaration, the Comprehensive Response Envelope for verifiable responses, and the Standardized HTTP GET Query Interface for predictable data retrieval.

How does OPP ensure data trustworthiness and integrity?

OPP ensures trustworthiness through a comprehensive response envelope that includes provenance (domain, source, freshness, citation), confidence scores, and Ed25519 cryptographic signatures for verifiable data integrity.

Can I implement OPP for my own data sources?

Yes, OPP provides SDKs and detailed specifications for data providers to implement the protocol. You can declare your data, wrap responses in the OPP envelope, and optionally sign them for cryptographic proof.

Establishes a protocol for data providers to make their data agent-consumable, verifiable, and discoverable.

The Open Primitive Protocol (OPP) addresses the problem of agents receiving data without provenance, freshness guarantees, confidence scores, or verification. It defines a structured approach for data providers, introducing three core components: a provider manifest, a standardized response envelope for all data, and a consistent query interface. The protocol supports various conformance levels, from basic data provision with freshness to fully verified data with cryptographic signatures, ensuring data integrity and trustworthiness for the agent internet.
