How this service works
Bitcoin fee estimates in sat per vByte for 1 to 144 block targets, with fast, standard and economy picks, mempool size and congestion level.
Output
A JSON object containing: the blockchain identifier (chain), current block height, an array of fee estimates in sat/vByte keyed by block target (1–144), a recommended object with fast/standard/economy picks, mempool size data, a congestion level string, a note with caveats, and the data source attribution.
Example use cases
Optimal fee for urgent Bitcoin send
“I need to send Bitcoin right now and want it confirmed in the next block or two — what's the current fast fee rate in sat/vByte and is the network congested?”
Budget transaction fee planning
“I'm not in a rush to send this Bitcoin — what's the economy fee rate right now and roughly how many blocks should I expect to wait for confirmation?”
Mempool congestion dashboard alert
“Check the Bitcoin mempool congestion level and current fee estimates across fast, standard, and economy tiers — I want to know if fees are spiking before I trigger any transactions.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/explorer/bitcoin/fees?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured Bitcoin fee recommendations across multiple confirmation-speed tiers in a single call, including mempool congestion context. It is especially useful for agents orchestrating Bitcoin transactions that need to dynamically select an appropriate fee rate based on urgency and network conditions, without building their own mempool monitoring infrastructure.
Side effects
- Upstream Bitcoin node or fee-estimation data source is unavailable, returning an error or stale data
- Network timeouts if the mempool is unusually large and query takes too long
- Invalid or unexpected response format if the provider's schema changes
- x402 payment failure if USDC balance or payment header is missing, blocking the request
