Interface directory

26 interface contracts and 41 specifications across 40 repositories. Every link points at an exact commit, so what you read is what that repository published rather than whatever its branch happens to hold today.

This directory is derived, not maintained

Entries come from what each repository declares in its own docs.manifest.json. A repository that publishes an API without declaring it will not appear here, and that is a bug in the repository rather than something to patch on this page. The documentation health page lists which repositories are not yet wired in at all.

Event and WebSocket interfaces

No repository currently declares a contract of this kind. When one does, it appears here automatically.

Protocol specifications

Normative specification documents. These are the authority for protocol rules; the Protocol Atlas summarises and compares them but never replaces them.

Conventions that hold across the estate

Indexer route prefixes

An indexer serves under its repository name with the index- prefix removed. The Patina indexer serves under /patina/.

The contract wins

Where a contract and its prose documentation disagree, the contract is correct and the prose is a bug. Report it against the owning repository.

Availability states are part of the interface

Responses distinguish unavailable from empty and unknown from zero. Collapsing those into "no results" corrupts anything computed downstream.

No endpoint asks for key material

Nothing in this estate asks for a seed phrase or a private key. Signing happens in your wallet.
