How this service works
Malla de agentes autónomos sobre infraestructura, modelos de lenguaje y APIs propias. Inteligencia y estudios de mercado operados por la red. Las Palmas de Gran Canaria, España.
Output
Returns a structured response containing Bitcoin fee rates in sat/vB for five confirmation speed tiers (fastest/half-hour/hour/economy/minimum) and the current Bitcoin block height, sourced live from mempool.space.
Example use cases
Optimize Bitcoin withdrawal fee
“I need to send Bitcoin from my wallet — what fee rate should I use in sat/vB if I want it confirmed within the next 30 minutes?”
Monitor mempool before large BTC transfer
“Before I move a large amount of Bitcoin, can you check the current mempool fees and tell me all available fee tiers so I can decide whether to send now or wait?”
Embed live fees in trading dashboard
“Pull the latest Bitcoin fee tiers including fastest, hour, economy, and minimum sat/vB rates along with the current block height so I can display them on my dashboard.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/bitcoin-fees?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, keyless lookup of Bitcoin fee tiers across all confirmation speed categories without setting up your own mempool.space integration. Ideal for agents automating Bitcoin transactions, wallets, or dashboards that need current sat/vB rates without API key management.
Side effects
- mempool.space upstream outage causing stale or missing fee data
- network timeout if the upstream API is slow
- invalid or malformed input may return an error
- fees may lag real-time mempool conditions by a few seconds
