Overview

LangChainBitcoin, maintained by Lightning Labs, provides two LangChain tool sets: one exposing an agent's on-chain and Lightning Bitcoin balance, and one for traversing L402-authenticated HTTP APIs (pay-per-request access via the Lightning Network). It ships as interactive Jupyter notebooks demonstrating both integrations rather than a packaged library.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — not run by us — no falsifiable install+entry probe from deploy_spec

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 40 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
