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 prose decision procedure brief tailored for the agent, including a recommendation on whether to purchase the prepaid credit package, key evaluation factors, risk flags (e.g. no balance attestation, short expiry, no refund terms), break-even analysis versus pay-per-call pricing, and metadata such as the model used, generation timestamp, and generation source (llm, reasoning, or deterministic).
Example use cases
Evaluating bulk credit discount offer
“An x402 API is offering me 5000 credits for $8, which works out to $0.0016 per call, versus their normal pay-per-call rate of $0.002. The credits expire in 60 days, there are no refunds, they've been operating for 2 years, and they do publish a verifiable balance attestation. My remaining budget is $15. Walk me through whether I should buy the prepaid package.”
Assessing risky merchant with no attestation
“A merchant wants me to prepay $10 for 2000 credits at $0.005 each — slightly cheaper than their $0.006 per-call rate — but the credits expire in 7 days, minimum purchase is $10, they have no refund or transfer policy, and I can't find any balance attestation I can verify. They've only been around for 3 months. My task budget is $12. Should I go ahead and buy?”
Deciding between credit tiers
“I'm looking at two prepaid credit tiers from an x402 merchant: a $2 pack of 400 credits ($0.005/credit) expiring in 14 days, or a $10 pack of 2500 credits ($0.004/credit) expiring in 90 days. Pay-per-call is $0.006. They publish a balance attestation and have a clean operational history. My remaining budget is $8. Which tier makes more sense, or should I just pay per call?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/buyer-side-decision-procedure-for-agents-offeredWhen to prefer
Use this endpoint when an AI agent has been offered a prepaid credit bundle by an x402 merchant and needs a structured, reasoned decision procedure before committing funds. It is especially valuable when the agent must weigh bulk discount pricing against expiry risk, lack of refund terms, or unverified merchant balance attestations — and when the agent's remaining task budget is a binding constraint. Prefer this over generic LLM reasoning when you want a consistent, service-specific decision framework that accounts for x402-specific risk factors like balance attestation verifiability and merchant operational history.
Side effects
- Payment not received — returns 402 if x402 payment header is missing or invalid
- Malformed query parameters may result in a generic or off-topic procedure
- No topic override provided and service derives topic from endpoint slug, which may be imprecise
- LLM generation failure could result in empty or truncated brief field
- Merchant data inputs are caller-supplied and not independently verified, so output quality depends on input accuracy
