How this service works
Deterministic procedure for agents after a facilitator top-up or insufficient-credits recovery: reconcile the posted top-up against the facilitator's settled totals, detect missing or double-credited amounts, verify the ledger matches settlement receipts, then select the pre-funding rail (facilitator A vs B, direct vs pay-per-call) by fee, latency, and redundancy before resuming traffic. Inputs: pre-top-up balance, top-up amount, post-top-up balance, facilitator settled totals, rail options
Output
A JSON object containing a plain-prose decision procedure (120+ words) as both 'brief' and 'procedure' fields, along with the topic, service slug, generation timestamp, and generation source (deterministic/llm/reasoning). The procedure guides the agent step-by-step through reconciling the top-up, detecting discrepancies, verifying the ledger, and selecting the optimal pre-funding rail.
Example use cases
Post-recovery rail selection for agent fleet
“My agent fleet just recovered from an insufficient-credits event on our x402 facilitator. We topped up $50 USDC. Can you reconcile the posted amount against our settled totals and tell us whether to resume traffic on the direct rail or pay-per-call, weighing fees and redundancy?”
Detecting double-credited top-up in ledger
“I think our x402 facilitator ledger was double-credited after a top-up — the pre-top-up balance was 10 USDC, we added 20, but the post balance shows 45. Can you run the reconciliation procedure to detect whether there's a missing or extra credit and flag the discrepancy?”
Selecting between two facilitator rails by fee and latency
“We're about to resume high-volume x402 traffic after a credit replenishment and need to decide between facilitator A and facilitator B rails. Can you give me the deterministic rail selection procedure comparing their fees, latency, and redundancy so I can pick the right one?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/facilitator-credit-reconciliation-and-pre-fundin?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent has just experienced an x402 insufficient-credits event or completed a facilitator top-up and needs a deterministic, structured procedure for both reconciling the credited amounts and choosing the best pre-funding rail. Prefer it over generic payment documentation when you need machine-readable, agent-actionable guidance that covers both ledger verification and rail selection in a single call.
Side effects
- Missing required query parameters may return an incomplete or generic procedure
- Non-payment (no x402 payment header) returns a 402 response requiring USDC payment before content is delivered
- Invalid topic override may result in mismatched procedure content
- Stale or cached procedures may not reflect the latest rail fee structures
