How this service works
108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.
Output
A JSON object containing the exchange rate data for the requested currency pair, including the rate value between the base and target currencies (e.g. USD→EUR). The exact schema is unspecified beyond the top-level object, but typical fields would include the rate, possibly timestamps, and currency identifiers.
Example use cases
Live forex rate for travel planning
“What's the exchange rate from USD to JPY right now? I want to know how much yen I'll get per dollar.”
Crypto price in fiat currency
“Can you get me the current BTC to USD exchange rate?”
Cross-currency business invoice
“I need to know the current EUR to GBP rate so I can figure out how much to invoice my UK client in pounds.”
Technical details
Endpoint
POSThttps://agenttoll.dev/paid/utility/currencyWhen to prefer
Use this endpoint when an AI agent needs a quick, pay-per-call currency conversion rate lookup without managing a subscription API key. Particularly useful for agents that only occasionally need forex data and want to avoid monthly billing, or when the use case spans fiat and crypto (e.g. BTC) in the same interface. Less suitable for high-frequency trading applications where latency and rate limits matter.
Side effects
- Invalid or unrecognized 3-letter currency code returns an error
- Unsupported currency pair may return empty or null rate
- Payment failure (insufficient USDC balance) blocks the call entirely
- Network or upstream data provider outage may cause timeouts or stale data
