A rolling read on the world: a 20-source roster distilled into one synthesized digest, republished every four hours. Poll the free brief and index, or pull history for depth.

Hit any Signalis endpoint with a plain HTTP GET. No signup, no key, no dashboard — just the URL.
Paid endpoints answer with an x402 payment challenge describing exactly what the call costs — from $0.01.
Your x402 client settles the micro-payment in USDC on Base and retries automatically. Structured intelligence comes back.
