Trend Radar: Trending topics radar, paid by the call.

Trending topics and breaking stories across tech, dev, science, business, culture, politics, and entertainment — aggregated from multiple public sources with regional and time-window filters. Flat sub-cent price per call; the cheap first stop for what is happening right now. No signup, no API keys — every request is paid in USDC through the HTTP 402 flow, and the exact price is quoted before you pay.

Quickstart

One endpoint: POST /api/tools/radar over HTTP, or the x_radar tool over MCP at POST /api/mcp.

curl -X POST https://twitr.sh/api/tools/radar \
  -H 'Content-Type: application/json' \
  -d '{"category":"tech","hours":24,"limit":20}'

# → 402 Payment Required with the exact USDC price.
# Pay it (x402 on Base/Solana, MPP on Tempo) and retry the same request → 200 + data.
# x402-aware clients do both steps automatically.

How to use it

Optional filters: category, region, hours (lookback), limit, source. Use report.next_cursor via `after` for the next page. Flat floor price per call.

The exact quote is returned in the 402 challenge before you pay — an agent always knows the cost first. Failed calls are never charged. Full input schema in the OpenAPI spec.
