Txs relayed = the wallet's on-chain transaction count (fact). Settled volume is an exact sum of the settlements we hold for this operator over 182 days. Payers/payees and share are from sampled 30-day discovery windows (estimates) — a share needs a site-wide denominator, which lives only on /stats. A facilitator typically rotates settlements across a wallet pool and keeps each on a thin, topped-up gas float. Every figure on this page covers the 1 attribution value that resolve to this operator, not just its group key.

Using Roundhouse, tell me what this x402 facilitator actually relays: volume, who it
settles for, and how steady it has been.

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.
