How this service works
Decision procedure for agents that are offered prepaid credit packages by x402 merchants (Browser Use + Coinbase style credit purchases, or any merchant selling prepaid balances). Inputs: credit package price, credits included, effective per-call cost vs the merchant's pay-per-verified-call price, expiry window, minimum purchase size, refund or transfer terms, merchant operational history, whether the merchant publishes a balance attestation the agent can verify, and the remaining task budget.
Output
A JSON object containing a plain-prose decision procedure of 120+ words tailored to buyer-side evaluation of prepaid credit packages, along with the LLM model used, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, topic, and service slug. The 'brief' and 'procedure' fields contain the actionable text an agent can read and act on.
Example use cases
Agent evaluating bulk API credit offer
“My agent just got offered a prepaid 500-call credit package from an x402 API merchant on Base — what decision procedure should it follow to figure out if this is worth buying?”
Autonomous agent pre-purchase reasoning
“Before my agent spends USDC on a prepaid credit bundle from an x402 service, what buyer-side checks and reasoning steps should it run through?”
Custom topic decision procedure for credit packages
“Generate a decision procedure for an agent evaluating a prepaid credit package from an x402 data-feed merchant — use 'market data feed prepaid credits' as the topic.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/buyer-side-decision-procedure-for-agents-offeredWhen to prefer
Choose this endpoint when an autonomous agent needs structured, LLM-generated reasoning to decide whether to accept a prepaid credit package from an x402 merchant on Base. It is distinct from generic 'should I buy this API' logic because it is purpose-built for the x402 protocol's prepaid-credit offer pattern, returns prose a downstream agent can directly act on, and costs only $0.002 USDC per call via x402 micropayment.
Side effects
- HTTP 402 returned if payment has not been settled — agent must pay exact USDC and retry with PAYMENT-SIGNATURE header
- Payment amount mismatch causes rejection
- Invalid or malformed query parameters may return validation error
- Service temporarily unavailable if K-2SO agent heartbeat is down
- Topic override ignored or defaulted if unsupported value provided
