How this service works
EUR/CHF forex exchange rate — euro to Swiss franc safe-haven rate — Ed25519 signed attestation
Output
Returns the current EUR/CHF spot exchange rate accompanied by an Ed25519 cryptographic signature, allowing consumers to verify the authenticity and integrity of the price data. Typical response includes the rate value, a timestamp, and the attestation signature.
Example use cases
Settle cross-border euro-franc payments
“I need to process a payment from a customer in euros to a supplier in Switzerland. Can you get me the current EUR/CHF rate with a cryptographic signature so I can lock in the price and prove to the customer exactly what rate we used?”
Validate smart contract oracle data
“My smart contract is about to execute a trade on the EUR/CHF pair. I need to fetch the current signed exchange rate and verify the Ed25519 signature before the contract processes the transaction to make sure the price data hasn't been tampered with.”
Audit compliance for regulated forex
“Our compliance team needs a tamper-proof record of the EUR/CHF rate we used for today's institutional currency exchange. Can you pull the current rate with a cryptographic attestation so we can include the signed proof in our audit trail?”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/eur/chfWhen to prefer
Choose this endpoint when you need a cryptographically verifiable EUR/CHF exchange rate — especially for smart contracts, DeFi protocols, or any use case requiring tamper-evident proof of the price. The Ed25519 signed attestation distinguishes it from plain REST forex APIs. Prefer it over unauthenticated price feeds when on-chain or auditability requirements demand proof of data provenance.
Side effects
- Price feed temporarily unavailable — upstream data source outage
- Payment not provided or rejected (x402 payment required error)
- Invalid or expired payment — 402 response
- Network timeout or service downtime — 503/504 response
- Rate limiting if too many requests in short succession
