How this service works
Deterministic decision procedure for gating autonomous x402 auto-pay inside browser agent runs. Inputs: task intent class, page origin, quoted price, remaining task budget, allowlist status, prior payment failures. Thresholds: auto-pay allow when quoted price <= 20% of remaining budget AND origin matches allowlisted scope AND intent class is pay-authorized; require human approval when price > 50% of remaining budget or origin is unvetted; hard kill when quoted price drifts > 2x from first
Output
Returns one of three verdicts — ALLOW_AUTO, REQUIRE_APPROVAL, or KILL — along with evidence fields explaining the decision, including which threshold was triggered (budget ratio, origin allowlist mismatch, price drift, or consecutive settlement failures).
Example use cases
Safe auto-pay within budget allowlist
“My agent is mid-task on docs.trustedsite.com and hit a 0.03 USDC paywall — my remaining budget is 0.50 USDC, the origin is in my allowlist, intent is pay-authorized, and no prior failures. Is it safe to auto-pay without asking me?”
Escalate large payment to human approval
“My browser agent wants to pay 0.35 USDC for a data export on a site I haven't vetted — my remaining task budget is 0.60 USDC. Should it proceed autonomously or flag this for my review first?”
Kill agent on price drift detection
“The browser agent started a task where the first quote was 0.02 USDC but now the site is quoting 0.06 USDC — that's more than 2x the original price. Should it abort the payment and kill the task?”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/browser-execution-payment-gate-decision-procedurWhen to prefer
Use this endpoint when you are operating a browser_use style autonomous agent that encounters x402 paywalled resources and needs a deterministic, evidence-backed decision on whether to auto-settle, escalate to human approval, or abort — especially when you need a consistent policy enforced across budget thresholds, origin allowlists, and failure streak detection rather than ad-hoc agent reasoning.
Side effects
- Missing or malformed required inputs (task intent class, origin, quoted price, budget) cause handler failure
- Origin or price values that cannot be parsed result in a failed ok response
- If the endpoint itself is unreachable the agent must default to REQUIRE_APPROVAL or KILL for safety
- Edge cases where budget is zero or negative may produce undefined threshold evaluations
