Example use cases

Technical details
Endpoint
GEThttps://x402.agentindex.world/crypto?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live cryptocurrency prices and 24h change data for up to 20 coins simultaneously, paid per-call in USDC on Base via x402. It is ideal for AI agents that need real-time market data without a subscription, especially for DeFi workflows, portfolio monitoring, or any use case requiring trustless, pay-per-use pricing. Prefer this over subscription APIs when usage is sporadic or when the agent must autonomously pay for data access on-chain.
Side effects
- Unknown coin ticker or CoinGecko ID returns an error or omits the coin from results
- Requesting more than 20 coins returns a validation error
- Unsupported vs_currency value may return an error or fall back to USD
- Payment insufficient or missing triggers a 402 response requiring USDC payment on Base
- Network or upstream CoinGecko outage may return a 5xx error
