How this service works
Procedure that grades what a wallet signature actually proves before an agent treats it as authorization. Classifies an incoming signature as one of three scopes: (1) payment-capability only, the signature proves the wallet moved value but nothing about intent; (2) delegated intent, the signed payload binds principal, agent ID, and purpose; (3) policy-conforming authority, the payload also references the governing policy, quote hash, or delegation record. Returns a verdict: accept as full
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) for grading wallet signature authorization scope, including the topic label, service slug, generating model name, generation source (llm, reasoning, or deterministic), an ISO-8601 timestamp, and the full procedure text repeated in the 'procedure' field — all wrapped with ok/paid status and provider attribution.
Example use cases
Pre-payment authorization scope check
“Before my agent settles an x402 payment, I want it to follow a proper procedure for checking whether the wallet signature actually covers the intended authorization scope — can you fetch that decision brief?”
Wallet permission grading for agent governance
“My agent governance system needs a written procedure for grading wallet signature authorization scope when evaluating incoming payment requests — fetch me the latest decision procedure for that.”
Onboarding new x402 merchant agent
“I'm setting up a new autonomous merchant agent on Base and I need to understand how to grade wallet signature authorization scope properly — get me the decision procedure brief for that topic.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/wallet-signature-authorization-scope-grading?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a structured, prose decision procedure specifically for evaluating wallet signature authorization scope in x402 or on-chain agent payment contexts. It is ideal for agents that need deterministic or LLM-generated guidance they can follow programmatically, rather than building their own heuristics. Prefer it over generic LLM prompting when you want a versioned, paid, catalog-listed procedure with a consistent schema and generation-source provenance.
Side effects
- HTTP 402 returned if payment not yet settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid HTTP method (POST, PUT, PATCH) returns error — only GET/HEAD/DELETE accepted
- Malformed topic override may cause unexpected or off-topic procedure generation
- Service unavailable on k2so.wrong.systems results in connection error
- Payment signature mismatch or replay attack causes authorization failure
