How this service works
Decision procedure for web-automation agents (Browser Use class) that hit an x402 payment wall mid-task. Outputs PAY, PAY_CAPPED, HOLD, or ABORT with thresholds: task value vs quoted price, remaining task budget, site reputation tier, per-site spend cap, paywall recurrence risk, and payment failure routing (retry once, then re-plan or escalate). Includes pre-payment challenge vetting: verify 402 challenge issuer, network, price sanity, and session binding before signing, plus post-payment
Output
A structured response containing a decision outcome label (PAY, PAY_CAPPED, HOLD, or ABORT), prose explaining the decision rationale, pre-payment challenge vetting results (issuer, network, price sanity, session binding), post-payment routing instructions including retry and re-plan logic, the generation source (llm, reasoning, or deterministic), and an ISO-8601 timestamp.
Example use cases
Mid-task paywall spend authorization
“My web agent is halfway through a research task and just hit an x402 paywall asking for $0.005 USDC. My total remaining budget for this task is $0.02 and I've already paid this site once before — should the agent pay, cap the payment, hold for approval, or abort? Walk me through the decision.”
Pre-signing x402 challenge vetting
“Before my agent signs an x402 payment challenge on this site, I want to make sure the challenge issuer, network, price, and session binding all check out — can you run the vetting procedure and tell me if it's safe to sign?”
Payment failure re-routing after x402 rejection
“My agent tried to pay an x402 wall, the payment failed, and now the site is still blocking access. Should the agent retry the payment, re-plan the task, or escalate to me — what's the recommended routing procedure here?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/decision-procedure-for-web-automation-agents-broWhen to prefer
Choose this endpoint when your web-automation or Browser Use agent needs a structured, threshold-based decision framework for x402 payment walls encountered mid-task — especially when you need both pre-payment challenge vetting (issuer, network, price sanity, session binding) and post-payment failure routing in a single call. Prefer it over ad-hoc agent logic when per-site spend caps, paywall recurrence risk, and task value vs quoted price comparisons need to be systematically evaluated.
Side effects
- Invalid or missing input method returns a validation error
- Unrecognized topic override may produce a generic procedure rather than a tailored one
- Payment for the $0.002 USDC call itself fails, blocking access to the procedure
- Stale or cached procedure if the service's LLM/reasoning backend is unavailable
- Network connectivity issues to k2so-8080.on.ascii.dev result in no response
