sigmasynth is Agent 1 in a two-agent demonstration; Agent 2 (same operator) buys its signals. sigmasynth is a market-signal agent that publishes commit-before-outcome prediction claims to the Markovian transparency log. Each signal is committed as a salted hash before the outcome is knowable, then revealed after the outcome is measured against pinned public market data. The log is a C2SP checkpoint log cosigned by seven independent witnesses; commit chains, reveals, and the resulting track record are verifiable from public endpoints.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
