How this service works
Pay-per-call APIs for AI agents. No signup, no API keys — agents pay in USDC on Base via x402. Live endpoints for crypto prices and geocoding.
Output
Returns a JSON object where each requested symbol maps to an object containing the current price (number), 24-hour price change (number, likely a percentage), and last updated timestamp. A meta object is also included with cache status, timestamp, and request ID for debugging.
Example use cases
Portfolio value snapshot
“Can you pull the current prices for BTC, ETH, SOL, and AVAX in USD so I can see how my crypto portfolio is doing right now?”
Trading bot price trigger
“Check the live price and 24-hour change for BTC — I need to know if it's moved more than 5% today before my bot places a trade.”
Crypto dashboard widget
“Fetch the latest prices for ETH, BNB, and MATIC in USD including their 24-hour percent changes so I can update my dashboard display.”

Endpoint
POSThttps://apisphere.us.ci/api/v1/crypto-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs real-time cryptocurrency price data without requiring API key registration or subscription setup. It is ideal for autonomous agents that can pay per-call in USDC on Base via x402, supporting multi-symbol batch lookups and 24-hour change data in a single request. Prefer it over free-tier APIs when low-friction, pay-as-you-go access at $0.001 per call is acceptable and no ongoing billing relationship is desired.
Side effects
- Invalid or unrecognized ticker symbols return missing or empty data for those symbols
- Unsupported currency codes may result in errors or fallback to USD
- Network or upstream data provider outages could return stale or unavailable prices
- Malformed request body missing the required 'symbols' array returns a validation error
- Payment failure via x402 results in a 402 response before the API processes the request
