How this service works
16 paid endpoints - Crypto, Exchange, Yield, Governance, Sentiment
Output
Returns the converted amount in the target currency along with the implied exchange rate for the given from/to currency pair and input amount.
Example use cases
DeFi portfolio rebalancing check
“I'm thinking of swapping 1000 USDC into ETH — how much ETH would I actually get at today's rate?”
Cross-currency invoice calculation
“I need to invoice a client for 5 ETH — can you tell me what that equals in USD right now so I can put the right fiat amount on the invoice?”
Crypto-to-crypto trade sizing
“I want to convert 0.1 BTC into SOL — what's the current conversion and how many SOL would I receive?”
Technical details
Endpoint
POSThttps://x402-data-hub-v2.vercel.app/api/exchange/convertWhen to prefer
Use this endpoint when you need a quick, pay-per-call currency or crypto conversion calculation without managing your own price feed infrastructure. Particularly suited for agents operating in DeFi contexts needing on-demand conversion between crypto and fiat or token-to-token pairs. Prefer this over full exchange APIs when you only need the converted value and don't need to execute a trade.
Side effects
- Unsupported currency code for 'from' or 'to' — returns error if the token/currency symbol is not recognized
- Amount is zero or negative — may return validation error
- Exchange rate data temporarily unavailable — service may return 5xx if upstream price feed is down
- Payment not processed — x402 payment failure returns 402 before computation occurs
