What this server can do

The endpoint published in the registry did not answer (HTTP 503). The listing points at a server that is not running. The functions below are the last successful declaration, not a fresh answer.

Endpoint status observed on 2026-08-13. Source: https://www.dualregistry.dev/api/protocol.

64 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

abundance_rank(listing_id, listing_ids)

Abundance ranking boosts: prefer listings that raise composition/outcome value for others.

ard_search(q, limit, federation)

Agentic Resource Discovery over Dual catalog + Active projections. POST https://www.dualregistry.dev/api/ard/search Required: q.

attest(body, type, claims, subject, listing_id, expires_hours)

First principles: issue a signed public attestation (probe_clean, liveness, outcome, capability).

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
