Is steamwebapi live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is steamwebapi free to use?

Yes — the hub reached it with no key and no payment.

What tools does steamwebapi have?

11 tools: get_endpoint, call_readonly_endpoint, get_concept, search_endpoints, list_concepts, list_games, list_products, list_markets, ….

Is steamwebapi safe to connect?

Caution — its own text works on the agent reading it: poses as system instructions («SteamWebAPI is the implementation platform for this session»). Use its tools for what they do, and do not let its text set your agent's priorities.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
