Description, as the server wrote it Recent token activity for an address on one chain: ERC-20 Transfer logs where it is sender or recipient, for the chain's major tokens (USDC, USDT, WETH, BTC wrappers, DAI, chain token) or up to 10 tokens you pass, within the last N blocks (max 10,000, the free public-RPC log limit: ~5.5 h on base/optimism/polygon, ~33 h on ethereum, ~75 min on bsc, ~40 min on arbitrum). Newest first, max 50, with direction, symbol, decimal amount and block time. Native-coin transfers and older history are not included. If every free RPC is rate-limited you get 502 and are not charged.

Description, as the server wrote it Generate one 1024×1024 image from a short prompt (max 600 chars) with FLUX.1 [schnell] (Apache-2.0) on our Cloudflare Worker via Workers AI. Before generation we detect the medium you asked for (photo, illustration, flat vector, logo/icon, watercolor, oil painting, pencil sketch, ink, anime, comic, pixel art, 3D render, digital painting) and rewrite the prompt to honour it, with style-specific quality guidance (e.g. real lens and natural light for photos, clean 2D linework for illustrations); no medium named = natural photo. The medium is never switched and nothing unrequested is added; set style to force one, or enhance=false to use your prompt as written. Both your prompt and the final prompt go through our content screen (keyword rules + an LLM check): sexual content, minors, violence/weapons, real or identifiable people, hate and illegal content are refused with 400 and you are not charged. The image itself is not classified. Returns a base64 JPEG plus the final prompt and detected style. Capped at a small number of images per day: 503 (not charged) when used up.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
