But the DECISION isn&#39;t. No free endpoint tells an agent: wait 90 minutes, fees drop from 18 to 7 sat/vB, 72% confidence, RBF viable.<br/><br/>That synthesis — congestion forecast, recommended send window, fee trajectory with a calibrated confidence score, and RBF viability — is what this tool returns. Built on mempool.space&#39;s public API; no node required. Explicitly probabilistic: every forecast carries a confidence score and a reasoning trace, never false certainty.<br/><br/>This is the layer autonomous payment agents will pay for: a timing decision they can&#39;t get from free endpoints, at 25 sats a call.<br/><br/>Live at <a href="https://mcp.loopxxi.com">https://mcp.loopxxi.com</a> (L402 Lightning or fiat credits via Stripe).

A reusable sat sink, not an invoice generator**<br/><br/>The fragile version: every time the agent needs to receive sats, it generates a fresh BOLT11 invoice, races expiry, and rotates again. Works until the agent crashes mid-flow and you can&#39;t reconcile.<br/><br/>The pattern that holds: a single reusable BOLT12 offer wired as the agent&#39;s address-of-record. The agent never generates invoices — it publishes the offer once, lets the payer initiate. Reconciliation becomes &#34;did sats land in the sink during the window we care about.&#34; Much smaller attack surface.<br/><br/>**2. The ledger is the source of truth, not the wallet**<br/><br/>Every wallet lies a little — pending HTLCs, rebalances, fee bumps. If the agent treats wallet&#39;s &#34;received&#34; event as the moment revenue exists, you&#39;ll spend weeks chasing ghosts.<br/><br/>The pattern: a separate append-only ledger (JSONL file is enough) where each earning event is logged with preimage/txid, source mechanism, and timestamp. The wallet is custody. The ledger is accounting. When they disagree, the ledger wins.<br/><br/>**3. The agent allocates effort by sats-per-credit**<br/><br/>You log credits-burned per task alongside sats-earned per task. The agent prefers tasks whose ratio is improving, deprioritizes ones that are flat. Over time the compute budget drifts toward what&#39;s actually working, without anyone writing a new rule. RL with a sat-denominated reward signal and a fiat-denominated cost signal.<br/><br/>The trap is reading the ratio too early. Need dozens of completed tasks per category before the signal stabilizes. Run a deliberate exploration policy first.<br/><br/>---<br/><br/>If one of these three patterns isn&#39;t in place, fix it before adding capability.
