18 endpoints.

* [Compare](/docs/api-reference/registry/compare) — `GET /api/v1/compare`\
  Compare several subnets side by side across the registry structure (completeness + surface counts), the live economics tier, and the live per-subnet health rollup — one call, requested order.
* [Coverage](/docs/api-reference/registry/coverage) — `GET /api/v1/coverage`\
  Fetch registry coverage summary.
* [Coverage By Network](/docs/api-reference/registry/coverage-by-network) — `GET /api/v1/{network}/coverage`\
  Network-scoped form of /api/v1/coverage — prefix the route with a network to choose which chain answers it.
* [Coverage Depth](/docs/api-reference/registry/coverage-depth) — `GET /api/v1/coverage-depth`\
  Fetch the machine-usable coverage depth scorecard and ranked enrichment queue.
* [Curation](/docs/api-reference/registry/curation) — `GET /api/v1/curation`\
  Fetch curation states by subnet.
* [Fixture Detail](/docs/api-reference/registry/fixture-detail) — `GET /api/v1/fixtures/{surface_id}`\
  Fetch one captured, sanitized live request/response fixture by surface id.
* [Fixtures](/docs/api-reference/registry/fixtures) — `GET /api/v1/fixtures`\
  Fetch the index of captured live request/response fixtures (which surfaces carry a sanitized sample).
* [Gaps](/docs/api-reference/registry/gaps) — `GET /api/v1/gaps`\
  Fetch interface gap report.
* [Lineage](/docs/api-reference/registry/lineage) — `GET /api/v1/lineage`\
  Fetch maintainer-approved cross-network subnet lineage (graduated subnets + the deploying-soon testnet pipeline).
* [Registry Leaderboards](/docs/api-reference/registry/registry-leaderboards) — `GET /api/v1/registry/leaderboards`\
  Fetch registry leaderboards computed live from the store + registry projections + the economics tier.
* [Registry Summary](/docs/api-reference/registry/registry-summary) — `GET /api/v1/registry/summary`\
  Fetch the registry-wide summary (completeness, top subnets, level counts, latest changes).
* [Review Attribution Candidates](/docs/api-reference/registry/review-attribution-candidates) — `GET /api/v1/review/attribution-candidates`\
  Fetch the attribution sweep's review queue.
* [Review Enrichment Evidence](/docs/api-reference/registry/review-enrichment-evidence) — `GET /api/v1/review/enrichment-evidence`\
  Fetch detailed candidate evidence behind the enrichment queue.
* [Review Enrichment Queue](/docs/api-reference/registry/review-enrichment-queue) — `GET /api/v1/review/enrichment-queue`\
  Fetch the prioritized all-subnet enrichment queue.
* [Review Enrichment Targets](/docs/api-reference/registry/review-enrichment-targets) — `GET /api/v1/review/enrichment-targets`\
  Fetch contributor-ready enrichment targets grouped by missing surface kind and review route.
* [Review Gaps](/docs/api-reference/registry/review-gaps) — `GET /api/v1/review/gaps`\
  Fetch contributor-targeted subnet gap priorities.
* [Review Profile Completeness](/docs/api-reference/registry/review-profile-completeness) — `GET /api/v1/review/profile-completeness`\
  Fetch profile completeness gaps for contributor targeting.
* [Subnet Gaps](/docs/api-reference/registry/subnet-gaps) — `GET /api/v1/subnets/{netuid}/gaps`\
  Fetch interface gap priorities and enrichment queue for one subnet.
