Heron
Heron publishes a real A2A Agent Card at the canonical /.well-known/agent-card.json path on its documentation host (docs.herondata.io). The card is served by Heron's Mintlify-hosted developer documentation and advertises a single skill — "herondata" — whose body is a published Agent Skill markdown document. The card was saved verbatim to a2a/heron-agent-card.json. The API host (app.herondata.io), marketing host (www.herondata.io) and dashboard host (dashboard.herondata.io) all return 404 on both the canonical and the legacy path.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Herondata herondata
Use when building financial data processing workflows, automating SMB underwriting with bank data, enriching transactions with merchant and category information, parsing bank statements and financial documents, or integrating with Plaid and other financial data sources. Agents should reach for this skill when working with end-user submissions, file uploads, transaction enrichment, financial analytics, or webhook-based event processing.

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
