Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/crypto/convertWhen to prefer
Use this endpoint when you need a quick, pay-per-call crypto-to-crypto conversion without setting up a full exchange integration. Suitable for agents that occasionally need unit conversion across multiple chains (ETH, SOL, AVAX, MATIC, etc.) and want to pay micro-fees in USDC via x402 rather than maintaining API keys or subscriptions.
Side effects
- Unsupported token pair returns an error or empty result
- Malformed query string causes a 400 bad request
- Rate limit or payment failure via x402 returns 402 Payment Required
- Unknown chain or token symbol results in no data returned
- Network timeout if upstream price feed is unavailable
