Wallet Signature Authorization Scope Grading
x402
Wallet Signature Authorization Scope Grading is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-20).
Classifies an incoming wallet signature into one of three authorization scopes (payment-capability, delegated intent, or policy-conforming authority) and returns a verdict on whether to accept it as full authorization.

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 structured verdict classifying the wallet signature as one of three scopes: (1) payment-capability only, (2) delegated intent, or (3) policy-conforming authority. Includes an 'ok' boolean, a human-readable decision procedure brief for agents, the service slug, topic, generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp.
Example use cases
Pre-authorization check before high-value action
“I just received a wallet signature from a principal before my agent executes a high-value transfer — can you grade its scope and tell me if it qualifies as full authorization or just proves they moved value?”
Delegated intent verification for multi-agent pipeline
“My orchestration agent got a signed payload that's supposed to bind the principal, my agent ID, and the task purpose — can you classify whether this signature actually counts as delegated intent before I let the sub-agent proceed?”
Policy-conforming authority check before contract execution
“Before I execute this on-chain action, I need to confirm the signed payload references the governing policy and quote hash — can you grade this wallet signature to see if it reaches policy-conforming authority scope?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/wallet-signature-authorization-scope-grading?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs to validate whether a wallet signature it received actually constitutes authorization — not just payment capability. Especially valuable in multi-agent pipelines where principals delegate authority to sub-agents and the scope of that delegation matters before executing consequential actions. Prefer this over generic signature verification when you need a three-tier scope verdict that distinguishes payment proof from intent binding from policy-conforming authority.
Side effects
- Missing or malformed input signature payload returns an error verdict
- Signature that cannot be parsed or verified may be classified as payment-capability only by default
- Network or upstream LLM failure may result in a failed generation with ok=false
- Ambiguous payloads without clear binding fields may receive a lower scope classification than expected
- Payment not confirmed results in 402 response requiring x402 payment before result is returned
