bolthub SDK
Source code for every publicly published bolthub.ai package — the npm @bolthub/* scope and the bolthub / bolthub-verify PyPI packages.
bolthub is an API marketplace where AI agents discover and pay for HTTP APIs per-call over Lightning (L402). These packages are the client side of that: payment clients, MCP servers, a CLI, and origin-verification middleware.
| Package | Registry | Directory | What it is |
|---|---|---|---|
@bolthub/agent | npm | packages/agent | L402 payment client — wallet adapters (LND, LNbits, Phoenixd, NWC, WebLN), 402 challenge handling, session cache |
@bolthub/mcp-registry | npm | packages/mcp-registry | MCP server exposing the whole bolthub marketplace to AI agents |
@bolthub/mcp-bridge | npm | packages/mcp-bridge | MCP server for a single bolthub gateway (one tool per endpoint) |
@bolthub/cli | npm | packages/cli | Terminal client for the marketplace |
@bolthub/verify | npm | packages/verify | Gateway signature verification middleware (Express/Fastify/Node) |
bolthub | PyPI | packages/agent-python | Python L402 client |
bolthub-verify | PyPI | packages/verify-python | Python gateway signature verification (Flask/Django/FastAPI) |
packages/shared is internal (never published); it is here because @bolthub/mcp-bridge bundles it.
Relationship to the bolthub platform
The bolthub platform (gateway, API, web app) lives in a private monorepo. The SDK packages above are developed there and synced to this repository, which is the publish origin: releases are tagged here and built + published by CI with npm provenance, so what's on npm is verifiably built from this public source.
Issues and PRs are welcome here. Accepted changes are applied to the monorepo first, then sync back out with the next release.
Verifying what you install
Published dist/ bundles are built with Bun from this source and ship source maps with embedded sources, so the tarball itself is readable.
# provenance: confirm the tarball was built from this repo by GitHub Actions
npm audit signatures
# or rebuild and compare yourself
git clone https://github.com/signaltech-org/bolthub-sdk
cd bolthub-sdk && bun install
cd packages/mcp-registry && bun run build
See SECURITY.md for the trust model (what touches your wallet credentials and what doesn't) and how to report vulnerabilities.
Development
bun install
bun test
Each TypeScript package builds with bun run build from its directory (@bolthub/agent must be built before the packages that bundle it).
