How this service works
Resolve a human-readable ENS name to a target address, verify current ownership and expiry or namewrapper status, confirm the reverse record matches before approving any agent payment, and choose between a marketplace purchase and direct registration based on cost, speed, and renewal risk. Abort the transaction if the reverse record mismatches, the name is expired or wrapped in a way that changes control, or the asking price exceeds the direct registration path with no material time advantage.
Output
A structured JSON response containing a prose decision-procedure brief (the 'brief' field) authored by an LLM or reasoning engine, covering: ENS forward/reverse record resolution steps, ownership and NameWrapper status checks, expiry and renewal risk assessment, marketplace-vs-direct-registration cost/speed comparison, and explicit abort conditions (reverse record mismatch, expired name, price exceeds direct registration with no time advantage). Also includes metadata: service slug, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, model used, and payment receipt details.
Example use cases
Pre-payment ENS name safety check
“I'm about to have my agent pay for the ENS name 'coolproject.eth' — can you run the ownership vetting procedure to confirm the forward and reverse records match, that it's not expired or wrapped in a suspicious way, and whether I should buy it from a marketplace or just register it directly?”
Detecting ENS name hijack risk before wallet transfer
“My agent is receiving a payment to 'myprotocol.eth' — please run the ENS ownership vetting procedure to confirm the reverse record actually matches that name and the current owner hasn't changed or wrapped it in a way that shifts control away from them.”
Marketplace vs. direct registration cost decision
“I want to acquire 'defi-tools.eth' — can you get me a decision brief on whether purchasing it from a secondary marketplace is worth it versus just doing a direct registration, factoring in the current asking price, renewal risk, and how fast I need it?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/ens-name-ownership-vetting-decision-procedureWhen to prefer
Choose this endpoint when an AI agent is about to approve a payment for or to an ENS name and needs a structured, opinionated decision procedure — not just raw resolution data. It is especially valuable when evaluating whether a marketplace purchase is justified over direct registration, when reverse-record integrity must be confirmed before funds move, or when the agent lacks internal ENS vetting logic. Prefer this over raw ENS resolver calls when you need actionable go/no-go guidance with explicit abort conditions rather than just lookup results.
Side effects
- Name resolution failure if ENS name is malformed or unregistered
- Stale or inconsistent data if the ENS subgraph is lagging behind on-chain state
- No topic override provided results in a generic procedure brief not tailored to a specific name
- Payment not confirmed leads to unpaid (meta) response without the full decision brief
- LLM generation timeout or error returns ok:false with no brief content
- Wrapped name edge cases may not be fully captured if NameWrapper state is complex
