Scro Orphan Desk A2A agent card is one of 2 APIs that [Scro Orphan Desk](https://apis.io/providers/dualregistry-dev/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include A2A, AI Agents, and Agent-Native. The published artifact set on APIs.io includes API documentation.

An A2A 0.3.0 agent card served at https://dualregistry.dev/.well-known/agent-card.json (and byte-identical at /agent-card.json, on www. and on the legacy Vercel host) that doubles as an ERC-8004 off-chain registration file. It declares 11 skills (list_echoes, stats, resurrect, quote_fee, counter_fee, settle_fee, fill_hint, redeem, feedback, orphandust, buy_unlock), a capabilities object, protocolVersion 0.3.0 and default JSON modes, and it grades conformant on the A2A 1.0.0 hard checks — but its url is the site root, which serves index.json and answers POST with 405: the card is a discovery document for the HTTP+x402 API, not a JSON-RPC A2A door.
