## When to prefer this

Choose this endpoint when you need a single aggregated, deduplicated view of crypto and blockchain news across four major newsrooms simultaneously. Ideal when you want to avoid calling each outlet's API separately or when you need keyword-filtered news quickly. Prefer this over general web search when you want structured, timestamped, source-attributed results specifically from CoinDesk, Cointelegraph, Decrypt, and The Block.

## Known failure modes

- No articles found for a very niche or misspelled keyword query — returns empty results
- Upstream newsroom feeds temporarily unavailable — may return partial results or error
- Invalid limit value (e.g. non-integer) — may return a 400 bad request
- Rate limit or payment failure via x402 — returns 402 Payment Required

## How this service works

Crypto and blockchain news from four newsrooms in one call (Cointelegraph, Decrypt, The Block, CoinDesk), deduplicated and sorted newest first: title, link, publication time, summary and source. Optional keyword filter. Query: ?q=bitcoin etf&limit=20

## Output

A list of deduplicated news articles sorted newest first, each containing: article title, link to original story, publication timestamp, summary text, and source newsroom name (Cointelegraph, Decrypt, The Block, or CoinDesk). Results are filtered by keyword if the ?q= parameter is provided and capped by the limit parameter.
