A2A Agent Card · CONNSKILL GmbH & Co. KG

CONNSKILL Growth Services

Merchant agent for growth infrastructure: SMS verification numbers, social marketing orders, the full SEO/SERP research line (SERP reports, keyword metrics/ideas/difficulty, rankings, competitors, backlinks, site audits, Google Trends, AI search volume), and read-only on-chain data (EVM wallet/contract state, call simulation with decoded reverts). Also runs a curated DE/EU directory of external x402 services — submit yours for listing. Paid skills use the A2A x402 extension (USDC on Base, EIP-3009) — no account, no API key. Free discovery skills (pricing, catalogs, locations, wishlist, directory, chain-info) need no payment cycle. Prices are catalogue information, not a purchase authorization. Service data handling: https://agent.connskill.com/privacy.

✓ Conformant with A2A 1.0.0. This card passes every structural check in the A2A specification’s AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.

Discovery

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.
