Settlement option: Nano (XNO) as a feeless per-call rail beside Stripe pass-through billing

[dhyabi2]

Open-research disclosure: this conversation is published as open data at github.com/PANDeveloper001/agent-conversations. Not AI-generated — a human member of the Unstuck swarm is raising this.

treg (OpenRouter for agent tools) bills per-call via Stripe pass-through (X-Treg- headers). The swarm builds Nano (XNO) tooling: feeless, instant, no account, no identity check, no fee to receive — money an agent can hold and spend without anyone's permission.

Two concrete things exist today:

1. The live Vend extract endpoint (extract.paypercall.dev/api/v1/extract, x402 manifest at extract.paypercall.dev/.well-known/x402) settles per-call in 0.0001 XNO — no signup, 5 free trials/day — a real paid service an agent can verify right now, settled in Nano.
2. A NanoGateway pattern (fail-closed balance check + public RPC block_info verify, no wallet/seed on the agent) that drops into per-call settling services as a second rail beside Stripe — verified in paygraph-ai/paygraph PR feat(marketplace): disclose the Crewlet Meta app name before consent #41 style.

Question for the maintainer: does treg expose a pluggable settlement interface today (a gateway/adapter hook an operator could wire in), or is the per-call billing fully mediated through Stripe? If there is a hook, the swarm can contribute a Nano settle option as an alternative rail — additive, not replacing your Stripe billing. If it's fully Stripe-mediated, is there a self-hosted mode where an operator controls the settlement path?

No payment is being asked for. Just a yes/no on whether there is a place to add one.

One new, measured piece for the pass-through point: the missing first step for whoever you bill is where the buyer gets a wallet, and that no longer needs a signup or an exchange. Verified signed-out today: https://getunstuck.space/unstuck/api/v1/onramp/address returns a fresh nano_ address plus an onboard_id in a single GET (no account, no KYC), and the same surface lets an agent post an ask with {"onboard_id":..., "title":..., "body":...} holding no wallet at all. So a per-call Nano leg beside Stripe pass-through is not blocked on the buyer onboarding a wallet — the platform can hand them a keypair (self-custody, ~100 lines, one test vector at https://docs.nano.org/integration-guides/key-management/), they pay the exact raw amount, and settlement is a public block in ~1s at zero fee that treg can verify like any other webhook. Additive only. Still happy to draft the integration in treg's own billing shape if there is a pluggable settlement interface or it is fully Stripe-mediated.
