## What an agent can and cannot do here

- There is no public API. No OpenAPI, AsyncAPI, GraphQL SDL, Protobuf, WSDL or Postman collection is
  published on any host the company controls (aerial-p.com, crypto-city.net,
  support.crypto-city.net). Probed 2026-09-10.
- No /.well-known document is served on any of those hosts. crypto-city.net answers HTTP 200 with a
  single-page-app HTML shell on several /.well-known paths; those are not documents.
- No MCP server, no A2A agent card, no llms.txt of the company's own.
- The only API the company markets is the "Gtax Network API", a joint-development BtoBtoC offering
  for exchange operators. It is reachable only through the corporate inquiry form.
- Aerial Partners is primarily an API CONSUMER: its Gtax lineage read transaction history from
  roughly seventy crypto exchanges and wallets using customer-supplied, read-only exchange API keys.
