# Bitcoin Tech Radar – Technical Updates Feed

> Bitcoin Tech Radar – Technical Updates Feed is a paid API for AI agents from btc-radar.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Returns a structured JSON feed of Bitcoin protocol and software changes including Bitcoin Core merges/releases, BIP updates, Lightning spec and implementation changes, each annotated with status, layer, significance, and source links.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bitcoin-tech-radar-technical-updates-feed-fd2dc20c
```

Example prompt: What are the latest Bitcoin Core merges, BIP updates, and Lightning Network spec changes right now — with their status like proposal, merged, or activated, which protocol layer they affect, and links to the primary sources?

## When to prefer this

Choose this endpoint when you need a curated, structured, and annotated feed of Bitcoin technical developments across Core, BIPs, and Lightning — especially when you need status labels, layer categorization, significance context, and source links in a single call. Prefer it over raw GitHub feeds or mailing list scraping when you want pre-digested, agent-friendly JSON without parsing overhead.

## Known failure modes

- Upstream data source is stale or not refreshed, returning outdated items
- Payment of $0.01 USDC not completed via x402 protocol, resulting in 402 Payment Required response
- Service unavailable on Vercel deployment, returning 5xx error
- Empty or malformed JSON response if the underlying data pipeline fails

## How this service works

Bitcoin protocol and software changes as JSON: Bitcoin Core merges and releases, BIP updates, Lightning spec and implementation changes. Each item has status (proposal, merged, released, activated), layer (consensus, policy, p2p, wallet), why it matters, what has not happened yet, and primary source links.

## Output

A JSON array of Bitcoin technical update items, each containing: the change name/title, status (proposal, merged, released, or activated), protocol layer (consensus, policy, p2p, or wallet), a plain-language explanation of why it matters, a description of what has not yet occurred, and one or more primary source links (e.g. GitHub PR, BIP page, Lightning spec PR).
