Documentation Overview

SatRank

Lightning trust oracle for AI agents on L402. Bitcoin-pure.

What this does

Crawls the L402 ecosystem (l402.directory + RSS + DNS) to build a catalogue of paid endpoints.
Probes each endpoint, classifying outcomes across 5 stages: challenge / invoice / payment / delivery / quality.
Scores every (endpoint, stage) pair as a streaming Beta(α, β) posterior. The end-to-end success probability is the product of stage means.
Ranks candidates on POST /api/intent (paid 2 sats via L402): an agent passes a category + budget + SLA, gets back the top-K endpoints with full Bayesian breakdown.
Publishes signed Nostr trust assertions (kind 30782) so any agent can cache / verify SatRank's output offline.

Public endpoints

Doc surfaces:

Code

GET  /                                 landing page (static HTML)
GET  /methodology                      technical reference (static HTML)
GET  /api                              API reference (static HTML)
GET  /openapi.json                     OpenAPI 3.0 spec (machine-readable)

Functional API (nine routes — POST /api/intent is the only L402-gated one):

Code

POST /api/intent                       paid, 2 sats via L402
POST /api/deposit                      free, mint a multi-use deposit macaroon (10–10000 sats, 30-day TTL)
GET  /api/deposit/:macaroon_id         free, read remaining balance
GET  /api/services/:url_hash           free, per-endpoint score snapshot
GET  /api/services/categories          free, list of catalogue categories
GET  /api/services/best                free, top-3 per category (5-min cache)
GET  /api/oracle/budget                free, last 24h revenue + paid-probe spend
GET  /health                           free, liveness
GET  /.well-known/satrank-key          free, oracle pubkey for offline verify

Deposit macaroons let an agent pre-pay N sats once and use the bearer preimage across many /api/intent calls without a Lightning round-trip per call. Authorization: L402 deposit_<id>:<preimage_hex>.

MCP

Three tools for any MCP-compatible AI runtime (Claude Code, Cursor, Codex, n8n):

Code

intent              forwards POST /api/intent (paid)
get_endpoint_score  forwards GET /api/services/:url_hash (free)
verify_assertion    offline Schnorr verification of kind 30782 (no network)

Install in Claude Code:

Terminal

claude mcp add satrank -- npx -y satrank-mcp

Self-hosters point SATRANK_API_BASE at their own deployment.

Run it

bash

cp .env.example .env
# minimum: set DATABASE_URL

npm install
npm run build
npm start

For paid probes + paid /api/intent gate, set LND_REST_URL + LND_MACAROON_HEX + L402_MACAROON_SECRET. For Nostr trust assertions, set NOSTR_PRIVATE_KEY.

Scoring math

For each (endpoint, stage), maintain a Beta(α, β) posterior with α₀ = β₀ = 1 (uniform prior). On every observation:

success → α += 1
failure → β += 1

Stage mean: α / (α+β). 95% credible interval via Wilson (closed-form). End-to-end success: ∏ stage_means across the 5 stages, assuming stage independence.

is_meaningful is true iff the challenge stage has at least MEANINGFUL_N_OBS_MIN observations. The challenge stage is observed on every probe (free or paid), so its n_obs converges fastest. p_e2e remains the honest end-to-end product separately.
