How this service works
Decision procedure for when an x402 endpoint returns no payment terms: no 402 challenge, HTTP 404/405, or a weak merchant contract. Covers probe interpretation, knock-or-backoff thresholds, alternate rail fallback, retry budgets, and kill criteria, ending in a single verdict.
Output
A JSON response containing a plain-prose decision procedure brief (120+ words) tailored to the topic of x402 endpoints returning paid responses without payment terms, including the generating model, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and service slug. The 'brief' and 'procedure' fields carry the actionable agent guidance.
Example use cases
Handling missing payment terms in agent pipelines
“My agent keeps hitting x402 APIs that return a paid response but don't include any payment settlement terms — give me a decision procedure brief so I know exactly what steps to take in that situation.”
Building a fallback handler for x402 payment gaps
“I'm writing logic for my autonomous agent to handle edge cases in x402 payments. Generate a decision procedure for what the agent should do when it encounters an endpoint that returned paid but provided no payment instructions.”
Auditing agent behavior on undocumented x402 endpoints
“I want to review how my agent should behave when it discovers an x402 service that gives a 402 response without explaining how to pay — can you pull a decision procedure brief covering this scenario?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-facing-decision-procedure-for-x402-endpoinWhen to prefer
Choose this endpoint when your AI agent needs a structured, LLM-generated decision procedure specifically for navigating x402 endpoints that return paid responses without payment terms — a niche but real edge case in autonomous payment flows. Prefer it over generic documentation lookups when you need actionable prose guidance your agent can directly interpret and act on, and when you are already operating within the x402/Base/USDC payment ecosystem.
Side effects
- Missing or malformed required 'input' object returns a validation error
- Calling with an unsupported HTTP method (POST, PUT, etc.) returns an error
- Payment not settled before retry results in continued 402 response
- Topic override that is too vague may produce a generic or low-utility brief
- Service temporarily unavailable returns a non-200 error with no result payload
