How this service works
Six payment-gated endpoints for AI agents: content extraction, price oracle, URL unfurling, web search, RSS parsing, and translation.
Output
Returns an array of price objects for each requested token, including current price (USD), 24h price change percentage, market cap, 24h trading volume, data source, and symbol, along with a count and timestamp.
Example use cases
Example prompt
“Can you look up the current prices for BTC, ETH, and SOL — including their 24-hour change and market cap?”
Technical details
Endpoint
POSThttps://agentfeed.up.railway.app/api/v1/pricesWhen to prefer
Use this endpoint when an AI agent needs real-time cryptocurrency price data for one or more tokens, especially when operating in an x402 micropayment environment on Base. Prefer this over free public APIs when operating within an agentic payment pipeline that already handles x402, or when structured multi-field market data (price, change, volume, market cap) is needed in a single call.
Side effects
- 402 Payment Required — x402 micropayment of $0.01 USDC not provided or invalid
- Invalid token symbol or CoinGecko ID returns empty or error result
- Network timeout from upstream price data provider
- Empty tokens array returns no results
- Rate limiting or provider downtime causing stale or unavailable data
