How this service works
Returns a signed Bitcoin mempool congestion snapshot, including congestion level, fee pressure, backlog estimates, and broadcast advice. The response includes an Ed25519 attestation for verification.
Output
Returns a congestion tier label (e.g. low/medium/high), a boolean fee-spike flag indicating whether fees are abnormally elevated, and a binary broadcast advice field (ok_to_broadcast or wait_or_pay_up) to help decide whether to submit a BTC transaction immediately.
Example use cases
Example prompt
“Check the Bitcoin mempool right now and tell me whether I should go ahead and broadcast my transaction or hold off — is there a fee spike and how congested is it?”
Technical details
Endpoint
GEThttps://obol-x402.fly.dev/v1/btc/congestionWhen to prefer
Use this endpoint when an agent needs a simple, actionable broadcast-or-wait decision for Bitcoin transactions without parsing raw mempool stats. It pairs congestion classification with a fee-spike flag and a plain-English recommendation, making it ideal for automated transaction scheduling or user-facing wallet assistants. Prefer this over raw fee-estimator endpoints when you want a tiered congestion label plus an explicit broadcast recommendation in one call.
Side effects
- Upstream mempool data unavailable — service returns error or stale data
- Payment not processed (x402 micropayment failure) — request rejected
- Rate limit exceeded — too many calls in a short window
- Mempool data temporarily lagging behind chain tip — advice may be slightly stale
