Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/bitcoin-fees-recommendedWhen to prefer
Use this endpoint when an AI agent needs to broadcast a Bitcoin transaction and must select an appropriate fee rate based on current mempool conditions. Ideal for wallets, payment automation, or any system that needs real-time fee estimation across multiple confirmation speed tiers rather than a single static estimate.
Side effects
- Upstream mempool data source unavailable — returns 5xx error
- Payment not processed or insufficient USDC balance — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Transient network error fetching live mempool data — may return stale or empty response
