Sponge: Gemini 2.5 Flash Image Preview - List Tasks

Use this endpoint when you need to check the status or retrieve a list of previously submitted Gemini 2.5 Flash image generation jobs via the Freepik Sponge/Paysponge proxy. Prefer this over direct Freepik API calls when you are already using the x402 payment flow through Paysponge for consolidated billing.

• Upstream Freepik API unavailable — returns 502 or 503 error
