Curated Paid API Directory for AI Agents

L402-gated agent reputation lookup. Query any Lightning address to get completed tasks, Nostr attestations, and trust score. Non-custodial task board with cryptographically signed reputation. 21 sats per lookup.

Added by scraper. Domain owners can authenticate for free to edit information.

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.

Finds and scores multiple trust paths between two pubkeys through the follow graph. Computes trust attenuation per hop (product of normalized WoT scores with mutual-follow bonus), identifies weakest links, and combines independent paths for an overall trust assessment. Useful for determining how two accounts are connected through mutual trust relationships.

Analyzes a pubkey's trust graph for anomalous patterns: follow-farming (high follow-back ratio), ghost/bot followers (zero-score followers), trust concentration (single-source dependency), score-follower divergence (many followers but low PageRank), and excessive following. Returns individual anomaly flags with severity levels and an overall risk assessment.

Without a pubkey, returns top 20 communities. With a pubkey, returns the community that pubkey belongs to with top members.

Leaderboard of the highest-ranked pubkeys in the trust graph with normalized scores and follower counts.

Batch spam filtering for contact lists or relay event feeds. Returns classification and probability for each pubkey plus summary counts.

Given a pubkey, fetches their kind 0 profile from relays, extracts the NIP-05 identifier, and bidirectionally verifies it resolves back to the same pubkey.

Jaccard similarity (70%) + WoT score (30%) to discover pubkeys with overlapping follow sets.

Batch scoring for clients that need to evaluate many pubkeys at once. Returns scores, follower counts, and composite scores.

Full transparency into score breakdown: PageRank component, engagement metrics, top followers with their scores, and external assertion details.

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.
