Frankfurter
by
API3FreeAirnode v0.1.4
Frankfurter's foreign exchange rates, blended from what central banks and other official sources publish rather than taken from any one of them. Latest and historical daily rates, reaching back to 1999 for the currencies that go that far. getCurrencies says which currencies are covered and getProviders which sources are blended, so a caller that needs either asks rather than assuming.
Every response carries an EIP-191 signature from the Airnode that served it, so the data can be attributed back to its source rather than trusted on reputation.

Served at https://airnode-frankfurter.fly.dev/. Each operation is reached the way the provider documents it, under https://airnode-frankfurter.fly.dev/api, and answers with the provider's own response and the attestation in headers, so a client built against the provider works unchanged. The same operations are also served as one JSON envelope on POST /, which the HTTP interface covers. Every request below can be sent from this page, and what comes back is verified right here in the browser.
ANY /api/…
The provider's own requests, one per operation, forwarded as they are. The provider's response comes back untouched, with the attestation in the X-Airnode headers.

Paste a response to verify it originates from the current Airnode: the JSON a POST / answers with, or a passthrough response with its headers, as curl --include prints it.
