Close
It costs Free per request, settled in USDC on Solana. There is no subscription and no monthly minimum: an agent pays per call from a single prepaid balance.
The agent calls POST /api/{exchange}/close through the Proxygate gateway with the Proxygate CLI, SDK, or MCP server. Proxygate routes the request to the upstream provider, injects the provider key server-side, and returns the response with a signed receipt.
No. The upstream provider key never leaves the Proxygate gateway. Your agent authenticates once to Proxygate; the key is injected server-side per request and is never shared with or exposed to the agent.
