AI postal agent — send physical letters to US, France, UK, Canada, Germany. Intent-driven pricing via ANP (Agent Negotiation Protocol). Cryptographic proof of sending via Verifiable Credentials, with delivery proof when a carrier/provider supplies it. The complete /mcp profile uses a subscription-backed API & MCP key. The ChatGPT /mcp/openai profile uses OAuth 2.1. For Business v2, API/MCP keys with send or full access and OAuth grants with send permission use a nominated licensed Team sponsor, while read-only credentials use no licensed sponsor slot. DID/UCAN-authenticated x402 A2A payment is REST-only at POST /api/orders/x402. Discoverable on the Olas Mech Marketplace (Agent NFT #58, Component NFT #328, Ethereum) and Fetch.ai Agentverse.

Sweeping the chain

We hold no settlements for this wallet. That is not the same as it having none, so we are looking: Queued. A worker will pick this up in a few seconds.

Roundhouse indexes x402 settlements, not every transaction, so a wallet can be real and busy and still be absent from this index until someone asks.

Data quality

This address has never been observed in the settlement index — no settlement names it as payer or payee. Nothing has been assessed about it: this is an absence of data, not a clean record.

Using Roundhouse, vet this agent for me: what is it, what has it paid for, and does its
on-chain record support what its card claims?

  Agent: 0xcd012cd3413e8288e0fb330fa37ac5d18a330c8b

Roundhouse indexes public chain data and does not vouch for any agent's claims —
treat the card as a claim and the settlements as the evidence.

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.
