How this service works
US GDP growth rate — quarterly economic output for macro regime and recession risk — Ed25519 signed attestation
Output
Returns the current US GDP value along with an Ed25519 cryptographic signature attesting to its authenticity, enabling downstream verification of data integrity by any consumer.
Example use cases
Smart contract recession monitoring system
“I need you to check the current US GDP figure from MyceliaSignal with its cryptographic signature — pull it every quarter and verify it's legit before feeding it into our smart contract that triggers recession hedges.”
Automated compliance reporting with proof
“Can you grab the latest US GDP attestation from MyceliaSignal and include the Ed25519 signature in our compliance report? Our auditors need to see that the economic data we're using is actually verified and tamper-proof.”
DeFi oracle data validation pipeline
“Set up a process to fetch the US GDP reading from MyceliaSignal with its signed attestation, then validate the signature and log it to our blockchain oracle feed — I want to make sure every data point we publish has cryptographic proof behind it.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/econ/us/gdpWhen to prefer
Use this endpoint when you need US GDP data that is cryptographically attested and verifiable — particularly for smart contracts, on-chain oracles, or any workflow where data provenance and tamper-resistance are required. Prefer it over plain REST economic data APIs when the consumer needs to independently verify the data source's signature.
