How this service works
Deterministic procedure for auditing an x402 facilitator's advertised transaction volume before you route settlement through it. Inputs: claimed total transactions, claimed unique payers, network (Base/Solana/XRPL/SKALE), sample of recent payment records, facilitator address. Checks: count-to-unique-payer ratio (volume concentration), cadence plausibility against timestamps, network consistency of the payTo address, whether the claimed volume exceeds the observable settlement ledger by a
Output
A JSON object containing a plain-prose decision procedure (120+ words) labeled 'brief' and 'procedure', the service slug, a generation timestamp, the model used (e.g. deepseek), generation source (llm/reasoning/deterministic), and the topic the procedure addresses. Also includes payment metadata confirming the $0.002 USDC payment was accepted.
Example use cases
Pre-integration facilitator due diligence
“Before my agent starts routing payments through a new x402 facilitator, give me the step-by-step verification procedure for checking whether their volume claims are legitimate.”
Automated compliance check for agent wallet
“My autonomous agent needs a decision procedure it can follow to validate an x402 facilitator's volume figures — pull the K-2SO brief so it can run the verification steps autonomously.”
Custom topic override for stablecoin facilitator
“Get me the K-2SO facilitator volume verification procedure but override the topic to focus on USDC stablecoin volume claims specifically, so the brief is tailored to that context.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/verification-procedure-for-x402-facilitator-voluWhen to prefer
Use this endpoint when an AI agent needs a structured, plain-language decision procedure specifically for verifying x402 facilitator volume claims, and wants an LLM-generated brief it can follow autonomously. Prefer over manual research when operating within the x402/Base USDC payment ecosystem and needing a ready-made compliance or due-diligence procedure at low cost ($0.002).
Side effects
- HTTP 402 returned if payment not yet settled — agent must pay exact USDC and retry with PAYMENT-SIGNATURE header
- Invalid HTTP method (POST, PUT) returns error — only GET/HEAD/DELETE accepted
- Malformed input schema (missing 'type' or 'method') causes request rejection
- Topic override may be ignored or defaulted if value is unsupported
- Service occasionally unavailable on k2so.wrong.systems if agent heartbeat is down
