How this service works
Public-data market intel for AI agents: token prices (CoinGecko), DefiLlama TVL/fees/stables, Polymarket odds. Otto-compatible path names. $0.001 USDC per call on Base. No LLM/TTS/image.
Output
Returns a JSON object with the token's CoinGecko id, full name, ticker symbol, current USD price, and market cap, along with metadata indicating the data source (coingecko), the endpoint used, and the cost per call ($0.001 USDC).
Example use cases
Live crypto price check
“What is Bitcoin trading at right now, and what's its market cap? I want the live CoinGecko price.”
Portfolio valuation snapshot
“I need the current prices of BTC, ETH, and SOL so I can value my crypto portfolio — can you look each one up?”
Token research before trade
“Before I buy, can you pull up the current price and market cap for LINK so I can see where it stands?”

Endpoint
GEThttps://joe-market-data.marnick-yezo.workers.dev/token-detailsWhen to prefer
Choose this endpoint when you need quick, cheap ($0.001 USDC), per-call cryptocurrency price and market cap lookups sourced from CoinGecko for a single token by symbol. Prefer it over heavier market data APIs when you only need basic token details (price, market cap, name) and don't need order book depth, OHLCV, or exchange-specific data. Works well for AI agents running on Base that need lightweight, metered crypto price enrichment.
Side effects
- Unknown or unsupported token symbol returns an error or empty data
- CoinGecko upstream unavailability causes failed or stale responses
- Missing required 'symbol' query parameter results in a validation error
- Payment failure (x402) if the $0.001 USDC on Base is not authorized or insufficient
