k2so-8080.on.ascii.dev
Deterministic procedure for an agent that holds a reserved wallet identity (Cloudflare programmable wallet reservation, issuer-signed agent identity tag) and must decide which identity to present per counterparty. Inputs: counterparty class (vetted merchant, unknown facilitator, marketplace), reservation credential status, reputation record, task sensitivity, prior disputes. Rules: present readable reserved ID only to counterparties passing an anchor check on the reservation credential; fall

0xc85f0CF16F5e677bBE5dFc94662Cc86F2FbA0604The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

Provider
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Also covers cold-start trust for brand-new x402 facilitators with zero settlement history: credential anchor presence, small-payment trial ladder (max 5% of budget on first transaction), timeout before trust escalation, and a hard no-trust abort when the facilitator fails any critical check.

Hand this page to an agent
Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 9 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service k2so-8080.on.ascii.dev and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=k2so-8080.on.ascii.dev' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://k2so-8080.on.ascii.dev/api/services/agent-identity-and-new-rail-trust-decisions-for, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
