How this service works
Paid agent-facing brief on agent decision procedure for x402 merchant endpoints that fail to quote: HTTP 404/405/no-402-challenge handling, knock-or-backoff, retry policy, alternative merchant fallback, contract quality scoring-0. Blunt decision procedure, not marketing.
Output
A structured JSON response containing a 'brief' field with prose decision procedure text, a 'procedure' summary, topic, service slug, generation source (llm/reasoning/deterministic), and ISO-8601 timestamp — along with payment confirmation metadata.
Example use cases
Handle silent x402 merchant failure
“An x402 merchant I'm trying to pay just returned a 404 with no payment challenge at all — what's the correct decision procedure: should I retry, back off, or immediately switch to a fallback merchant?”
Retry policy for non-402 x402 responses
“My agent keeps hitting 405 Method Not Allowed on an x402 endpoint instead of getting a 402 payment prompt. Give me a concrete retry and backoff policy so I know when to give up and try an alternative provider.”
Contract quality scoring for failing endpoints
“I need to score the quality of an x402 merchant endpoint that intermittently refuses to issue a 402 challenge — what's the decision procedure for evaluating contract quality and deciding whether to blacklist it?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/agent-decision-procedure-for-x402-merchant-endpoWhen to prefer
Choose this endpoint when your agent encounters x402 merchant endpoints that fail silently (404, 405, or no 402 challenge) and you need a concrete, opinionated decision procedure — not generic HTTP error handling advice. It is specifically tuned for the x402 payment protocol context, covering knock-or-backoff logic, retry policies, merchant fallback selection, and contract quality scoring in one paid brief.
Side effects
- Endpoint returns 404/405 if merchant is misconfigured or unavailable
- No 402 challenge issued if the payment layer is not functioning
- Missing 'brief' field if LLM generation fails
- Stale or cached procedure if generatedAt timestamp is old
- Payment rejected if USDC balance is insufficient for the $0.002 call fee
- Topic override ignored if not recognized by the service
