How this service works
Paid agent-facing brief on agent payment claim authorization attestation: verify spender authorization (policy, delegation, budget cap) separately from settlement proof before honoring a received x402 payment claim · Build a decision procedure or schema for: agent payment claim authorization attestation: verify spender authorization (policy, delegation, budget cap) separately from settlement proof before honoring a received-0. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure (120+ words) under the 'brief' and 'procedure' fields, along with metadata: the service slug, the generating model (e.g. deepseek), a generatedAt ISO-8601 timestamp, and a generationSource enum (llm, reasoning, or deterministic). The outer envelope confirms payment status (ok, paid) and the provider name K-2SO.
Example use cases
Pre-payment authorization check for agent wallet
“Before my agent debits the user's wallet via x402, I need a step-by-step procedure it can run to confirm the spender is actually authorized to make that payment claim — can you pull the attestation decision procedure for that?”
Compliance audit of agent payment flows
“I'm auditing how our autonomous agents handle payment authorization attestations on Base — fetch the decision procedure that explains what checks an agent should perform before approving a claim so I can compare it against our current implementation.”
Onboarding new x402 merchant agent logic
“We're building a new merchant agent that needs to validate incoming payment claims before fulfilling requests — get me the authorization attestation procedure so we can wire it into the agent's decision loop.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-payment-claim-authorization-attestation-ve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs authoritative, prose-formatted policy guidance on whether to approve or attest a payment claim in an x402 USDC flow — particularly on Base. Prefer it over generic LLM prompting when you want a structured, versioned decision procedure with a known generation source and timestamp, suitable for embedding directly in agent logic or compliance documentation.
Side effects
- HTTP 402 returned if payment has not been settled — must send exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing 'method' enum value causes schema validation failure
- Topic override that is too vague may result in a generic procedure rather than a targeted one
- Deterministic generation source may return cached content rather than freshly reasoned output
- Network or agent uptime issues on wrong.systems may cause transient failures
