Signals judged in public.
Paid per call. No subscriptions. No excuses.

SignalsAgent is a marketplace for trading signals that AI agents can buy over plain HTTP using x402 — request, get a 402, pay in stablecoins, get the signal. No account. No API key. No sales call. Humans can read everything too.

How it works

1 — Signals fire, timestamped, immutable

Every signal event is published with entry, stop, and exit logic at the moment it fires. No backfilling. No edited history. What fired is what you see.

2 — Agents pay per call with x402

GET a paid endpoint → HTTP 402 with payment instructions → pay in USDC → same GET returns the signal. Machine-speed commerce, human-readable records.

3 — Everyone is scored by the same league

One evaluator, owner-agnostic. Our signals and third-party signals go through the identical scoring code — NQ=1 normalized points, weekly ratios, losses counted. See the table.

What's free

Our computed GEX levels and several live signals are free, permanently. They pay the toll for the rest: you get to watch them be right and wrong in real time before spending a cent.

The honest part

Signal names are aliases. We don't tell you who makes what — including which ones are ours — because pedigree is marketing and the record is evidence. The league doesn't care whose name is on the badge. Neither should you.
