Web of Trust (WoT) Skill

Pre-transaction counterparty risk assessment using Nostr Web of Trust scores. Accepts Nostr hex pubkeys or npub1... bech32 addresses only.

Consolidated replacement for nostr-wot (deprecated) — adds taproot/stacks key sources, trust-path and recommend endpoints, and unified paid fallback.

52K+ pubkeys indexed with 2.4M+ trust edges
Trust edges weighted by zap receipts (economic signal, harder to fake)
Free tier: wot.klabo.world (50 req/day per IP), no key required
Paid fallback: maximumsats.com/api/wot-report (100 sats via L402) when free tier exhausted
1-hour local cache to avoid redundant API calls

This is a doc-only MCP-tool skill. Agents derive the Nostr pubkey via nostr_get_pubkey and then call external WoT APIs directly. There is no wot.ts CLI entrypoint.

Key Derivation

Use nostr_get_pubkey to get the agent's Nostr pubkey before calling WoT API endpoints:

nostr_get_pubkey({})

Returns { pubkey: "2b4603d2...", npub: "npub1abc..." }.

Key Source

Value	Path	Description
`nip06` (default)	`m/44'/1237'/0'/0/0`	NIP-06 standard — compatible with Alby, Damus, Amethyst
`taproot`	`m/86'/coin_type'/0'/0/0`	Taproot x-only key — same keypair as bc1p address
`stacks`	`m/84'/coin_type'/0'/0/0`	BTC SegWit path — backward-compat with pre-NIP-06 agents

What WoT Accepts

Format	Example	Works
Nostr hex pubkey	`2b4603d2...` (64 hex chars)	Yes
Nostr npub bech32	`npub1abc...`	Yes
Stacks address	`SP1ABC...`	No — hashed
BTC address (bc1q/bc1p)	`bc1q...`	No — hashed

Trust Thresholds

Rank	Meaning
1–100	Elite (top 100 Nostr users by WoT)
101–1000	Well-connected, high economic activity
1001–10000	Active community member
>10000	Low trust, new account, or no Nostr activity
