How this service works
GDP annualized growth probability distribution from Kalshi — expected value, entropy, per-period implied distribution — Ed25519 signed attestation
Output
A JSON response containing the annualized GDP growth probability distribution derived from Kalshi markets, including the expected value (mean implied growth rate), entropy (a measure of forecast uncertainty), and per-period implied probability distribution across growth scenarios. The response is accompanied by an Ed25519 signed attestation for cryptographic verification of data integrity and provenance.
Example use cases
Fed policy scenario analysis
“What does the prediction market currently imply about annualized GDP growth — give me the expected value and the full probability distribution so I can model Fed rate decision scenarios?”
Macro uncertainty dashboard
“Fetch the latest GDP growth probability distribution from Kalshi, including the entropy score, so I can display market uncertainty levels on my macro dashboard.”
Verifiable economic data pipeline
“I need a cryptographically signed snapshot of the current Kalshi GDP growth distribution — expected value, entropy, and per-period breakdown — that I can store and audit later.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/prediction/gdpWhen to prefer
Choose this endpoint when you need a probabilistic, market-implied view of GDP growth rather than a single-point official estimate. Ideal when you want prediction-market-derived distributions (not just BLS or Fed projections), need cryptographic attestation for auditability, or are building systems that require verifiable macro signals. Prefer over raw Kalshi scraping for convenience, signing, and structured output. Complement with the US unemployment rate endpoint from the same provider for a full Fed dual-mandate picture.
Side effects
- Payment failure: x402 payment not accepted, returns 402 Payment Required
- Kalshi data unavailable: upstream prediction market data temporarily unavailable
- Stale data: distribution may reflect last available Kalshi snapshot if markets are closed
- Invalid request: malformed GET request returns 400 Bad Request
- Service unavailable: returns 503 if Mycelia Signal infrastructure is down
