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.

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will read 0x21ab…01d9's settlement record over the free read API. No key, no account.

This relayer has no named operator in the facilitator registry yet, so it is identified by its wallet.

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.
