The Best Curated L402 + x402 API Directory

Returns current L402 paywall metadata including free tier and priced endpoints.

Evaluates the quality of who a pubkey follows, scoring each follow by trust score and categorizing into tiers (strong/moderate/weak/unknown). Returns an overall quality score (0-100), breakdown metrics (avg trust, reciprocity, diversity, signal ratio), category counts, and suggestions for low-quality follows to reconsider. Useful for Nostr clients to help users curate healthier follow lists.

Returns the trust circle (mutual follows) for a pubkey with per-member scoring, shared follow counts, mutual strength metrics, and aggregate circle analytics including cohesion, density, and role distribution. The inner circle highlights the top 10 most-trusted mutual connections.

Returns trust scores for a pubkey from our engine and all known external NIP-85 providers. Includes consensus metrics (mean, median, standard deviation, agreement level). Demonstrates NIP-85 interoperability — different providers independently scoring the same pubkey.

Computes graph-theoretic health metrics: degree distribution, connectivity, reciprocity, Gini coefficient of score centralization, power-law exponent, and top hubs. Returns an overall health score (0-100) and classification.

Analyzes up to 50 pubkeys in a single request, returning each one's trust score, percentile rank, follower metrics, mutual connections, 2-hop reach estimate, and network role classification (hub, authority, connector, consumer, observer, participant, isolated). Results sorted by trust score descending. No simulation — uses pre-computed PageRank for fast O(1) per-pubkey lookups.

Returns service status (starting/ready), graph size, event counts, external provider stats, authorization counts, and uptime.

Combines infrastructure trust data from trustedrelays.xyz (reliability, quality, uptime) with operator social reputation from PageRank. 70/30 blend of infrastructure and social scores.

Graph size, edge count, algorithm parameters, relay list, rate limits, and last build timestamp.

Returns all collected metadata: follower count, post/reply counts, reactions, zaps, topics, active hours, reports sent/received, and account age.

Returns engagement metrics (comments, reposts, reactions, zaps) and a normalized rank for a specific event ID.

Returns normalized PageRank trust score (0-100), composite score from external NIP-85 providers, follower count, engagement metrics, topics, active hours, and reports. Accepts hex pubkeys or NIP-19 npub format.
