### Tool changes

- 2026-10-29 `trending_topics` added
  - Lists topics trending right now across Google Trends (US realtime) and Polymarket (markets moving on volume), merged by topic, strongest first, each with score, score velocity per hour, first and last seen times, a type label (person, brand, event, place, meme, other), the headlines or market numbers behind it, and how many pump.fun launches in the last hour match it. Sources are polled every five minutes. Price: $0.01 per call in USDC (x402).
- 2026-10-29 `recent_launches` added
  - Lists pump.fun token launches from the last N minutes (decoded from Solana mainnet within about a minute), each with its creator wallet, that wallet's seven-day launch count, and, when the coin's name matches a topic currently trending on Google Trends or moving on Polymarket, the matched trend with its source and score. Launch data only; it does not rate, recommend or trade anything. Price: $0.005 per call in USDC (x402).

## Tools (5)

- `host_file`: Hosts a file: upload up to 10 MB as base64 with its content type and get back a public download URL that serves the bytes with that content type for 1 to 168 hours (default 24). Downloads are free, readable at once where uploaded and everywhere within about a minute. Executables are refused; HTML and SVG are served as attachments. A failed upload is not charged. Price: $0.01 per call in USDC (x402).
- `recent_launches`: Lists pump.fun token launches from the last N minutes (decoded from Solana mainnet within about a minute), each with its creator wallet, that wallet's seven-day launch count, and, when the coin's name matches a topic currently trending on Google Trends or moving on Polymarket, the matched trend with its source and score. Launch data only; it does not rate, recommend or trade anything. Price: $0.005 per call in USDC (x402).
- `render_page`: Renders a public web page in a real headless browser (JavaScript runs, redirects are followed) and returns it as clean markdown, a PNG screenshot or a PDF. One call, one payment, no account. A render that fails is not charged. Price: $0.01 per call in USDC (x402).
- `schedule_callback`: Schedules a delayed HTTP callback: give a public URL, an optional JSON body, optional headers and a delay of 60 seconds to 7 days (or an absolute time), and the URL is called at that time (POST when a body was given, otherwise GET), with one retry and a 10-second timeout. The answer carries a free status URL that reports whether it fired and what the callee answered. A request that is refused is not charged. Price: $0.005 per call in USDC (x402).
- `trending_topics`: Lists topics trending right now across Google Trends (US realtime) and Polymarket (markets moving on volume), merged by topic, strongest first, each with score, score velocity per hour, first and last seen times, a type label (person, brand, event, place, meme, other), the headlines or market numbers behind it, and how many pump.fun launches in the last hour match it. Sources are polled every five minutes. Price: $0.01 per call in USDC (x402).
