The BoltzPay Registry is a live index of paid API endpoints across x402, L402, and MPP protocols. It scans, scores, and indexes every endpoint every 6 hours using EWMA-weighted health scoring.

Overview

Browse the registry at status.boltzpay.ai.

SDK Integration

discover() queries the registry API. No static directory is bundled with the SDK.

Filters

All filters are server-side — the registry handles filtering and pagination.

Scoring

Each endpoint receives a trust score from 0 to 100 based on:
  • Availability — uptime over the last 30 days (EWMA-weighted)
  • Response time — latency consistency
  • Protocol compliance — correct 402 response format
  • Price stability — consistent pricing across scans
  • Multi-source verification — confirmation from multiple independent sources (capped bonus)
Dead endpoints with no history score 0. New endpoints start with an optimistic cold-start score that converges as data accumulates.
