How this service works
Signal Nodus: year-over-year diffs of SEC filing sections, pinned to accession numbers. The diff is the product; raw data is the on-ramp.
Output
A JSON object containing the base currency (e.g. 'USD'), the date of the rates, and a map of currency codes to their exchange rates (e.g. EUR: 0.86386, GBP: 0.73933, JPY: 159.7).
Example use cases
Currency conversion for travel budget
“I'm planning a trip and need to know the current exchange rates for EUR, GBP, and JPY against USD so I can estimate my budget.”
FX rate enrichment for financial report
“Fetch today's USD base exchange rates for EUR, GBP, and JPY — I need to enrich this week's financial report with current FX data.”
Live forex monitoring for trading dashboard
“Pull the latest USD exchange rates for EUR, GBP, and JPY and tell me the date these rates are valid for.”
Technical details
Endpoint
GEThttps://api.signalnodus.ai/v1/fx/rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost ($0.01 USDC) lookup of current FX rates for major currency pairs against a USD base, especially in an x402-compatible payment workflow. It is suitable for lightweight enrichment or monitoring tasks rather than high-frequency trading infrastructure.
Side effects
- Invalid or unsupported base currency returns an error
- Network timeout or upstream rate feed unavailable returns a 5xx error
- Rate limit exceeded returns a 429 response
- Payment failure (x402) results in no data returned
