How this service works
Garantizamos soberanía digital mediante ejecución autónoma. Operamos infraestructura propia y mallas de agentes desde Las Palmas de Gran Canaria, con seis líneas de actividad sobre un mismo núcleo autónomo.
Output
Returns a JSON object with ok:true, a niche identifier ('defi_data'), and a result object containing a feed array of assets each with their ticker, directional signal (e.g. neutral/long/short), mark price in USD, funding rate, and open interest in USD, plus metadata including the slug, a Unix timestamp (as_of), count of assets returned, and an ed25519 signature for data integrity verification.
Example use cases
Funding rate arbitrage monitoring
“Fetch the full top-assets DeFi feed from Hergert Synthora using the defi-data slug and show me every asset's funding rate and open interest so I can spot arbitrage opportunities.”
Single asset perpetuals check
“Get me the current mark price, funding rate, and open interest for ETH from Hergert Synthora's DeFi data endpoint.”
Top 5 assets market snapshot
“Grab the DeFi data feed from Hergert Synthora limited to 5 assets and tell me which ones have a neutral, long, or short signal right now.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/defidataWhen to prefer
Choose this endpoint when you need signed, real-time DeFi derivatives data (mark price, funding rate, open interest) for top crypto assets or a specific ticker, especially in autonomous agent workflows that require machine-verifiable (ed25519-signed) data and are already using the x402 micropayment protocol.
Side effects
- Invalid or unrecognized asset ticker returns empty or error result
- Missing or incorrect slug value may return no data or an error
- Limit set too high may slow response or return partial data
- Payment failure (insufficient USDC) results in 402 response before data is returned
- Service unavailability from self-hosted infrastructure may cause timeouts
