Endpoint
GEThttps://workspace-x402-paywall.onrender.com/ref/define?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-use dictionary definition lookup without a subscription, especially when integrating into an agent that only occasionally needs word definitions and wants to pay $0.005 USDC per call via x402 on Base or Solana mainnet rather than maintaining a paid dictionary API key.
Side effects
- Missing 'word' parameter returns a 400 error
- Unknown or misspelled word may return empty or null result
- Payment not included or insufficient USDC triggers 402 Payment Required
- Network timeout on the hosted Render service under cold-start conditions
