How this service works
Bitcoin broadcast-timing decision feed for agents: next-block fee estimate sat/vB, fee TREND (rising/falling since last poll), broadcast verdict (broadcast now / wait / wait briefly), economy-tier savings %, recheck-in-seconds, mempool backlog, congestion tier, fee-spike flag, tip height, BTC spot. Poll each cycle to time a BTC broadcast and minimize fees — should I broadcast now? ... Cryptographically signed (Ed25519) — every response is independently verifiable via /.well-known/obol-pubkey.
Output
Returns a structured decision feed including: next-block fee estimate in sat/vB, fee trend direction (rising/falling since last poll), a broadcast verdict (broadcast now / wait / wait briefly), economy-tier savings percentage, seconds until recommended recheck, mempool backlog stats, congestion tier label, a boolean fee-spike flag, current chain tip height, and BTC/USD spot price. The entire payload is cryptographically signed with Ed25519 for tamper verification.
Example use cases
Example prompt
“I'm about to broadcast a Bitcoin transaction — check the mempool right now and tell me whether I should send it immediately or wait a bit to save on fees.”
Technical details
Endpoint
GEThttps://obol-x402.fly.dev/pulseWhen to prefer
Use this endpoint when an agent needs a high-level, actionable broadcast-timing decision rather than raw fee data. It synthesizes mempool backlog, fee trends, and congestion into a single verdict ('broadcast now / wait / wait briefly'), saving the agent from having to implement its own decision logic. Prefer this over raw fee-rate endpoints when you want a pre-interpreted recommendation with trend context and a recheck timer. The Ed25519 signature provides verifiability for audit trails.
