Market facts and security signals for a Base token.
Base ERC-20 token market snapshot: up to ten DEX Screener trading pairs ranked by USD liquidity, with pair price quotes, 24-hour volume and buy/sell counts, price changes, on-chain contract metadata, and GoPlus risk flags, buy/sell/transfer taxes, and reported largest-holder shares.

Shareable output · US$0.02 per request
A market snapshot made to share.
A rule-generated, shareable SVG summary of public Base ERC-20 contract facts and the most liquid indexed DEX pair. It only attributes price change to the token when it is the pair's base token. The card is for entertainment and sharing, not a safety verdict, forecast, or investment recommendation. US$0.02 per request. It includes an escaped SVG card and the underlying pair facts, with change attributed only when the token is the pair's base token.

Inspect request and response schemasWhat this response does not claim
- It does not provide a safe/unsafe verdict or predict future prices.
- A zero or missing GoPlus flag is not proof that a token is safe.
- Indexed market data can be delayed, incomplete, or temporarily unavailable.
- Contract reads report public state; they do not prove ownership, audit quality, or investment merit.
