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 current USD price, market cap, 24h trading volume, 24h percent price change, and the CoinGecko token ID, plus metadata about the data source, endpoint used, cost in USDC, and a request ID.
Example use cases
Live portfolio valuation check
“Can you pull the current price and 24-hour change for BTC so I can see how my portfolio is doing today?”
DeFi trading signal monitor

Endpoint
GEThttps://joe-market-data.marnick-yezo.workers.dev/token-priceWhen to prefer
Choose this endpoint when you need a single, current token price with market cap, volume, and 24h change for any major or mid-cap cryptocurrency, especially in agent workflows that already use the x402 micropayment protocol on Base. It is purpose-built for AI agents with Otto-compatible path names and a very low per-call cost ($0.001 USDC). Prefer it over direct CoinGecko API access when you need a hosted, agent-friendly wrapper without managing CoinGecko API keys.
Side effects
- Unknown token symbol or CoinGecko ID returns an error — ensure the ticker (e.g. ETH) or CoinGecko slug (e.g. 'ethereum') is valid
- Payment failure if the calling agent's Base wallet lacks sufficient USDC (cost is $0.001 per call)
- CoinGecko upstream outage may cause a 502/503 response
- Rate limiting from the upstream CoinGecko API may cause transient failures
