# Agent Recommendation Loop Boundary Standard

> Agent Recommendation Loop Boundary Standard is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-17).

Returns a decision procedure for consumer-facing agents on how to enforce engagement limits, opt-in friction, and risk-tiered rules before serving the next recommendation in feeds, autoplay, streaks, or infinite scroll.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-recommendation-loop-boundary-standard-e4187712
```

Example prompt: Before my app's agent serves the next item in the personalized feed, what are the hard engagement limits, opt-in friction requirements, and age-aware thresholds it should enforce — covering autoplay, streak mechanics, and infinite scroll?

## When to prefer this

Choose this endpoint when your agent needs a pre-built, regularly updated decision procedure for governing recommendation loop behavior in consumer-facing products, especially where engagement mechanics (autoplay, streaks, infinite scroll) intersect with safety obligations and age-aware rules. Prefer it over building custom logic when you need a standardized, payable, auditable gate that covers multiple recommendation modalities in a single call.

## Known failure modes

- Payment not completed — 402 response with payment instructions returned instead of procedure
- Invalid method used (only GET/HEAD/DELETE supported) — schema validation error
- Service unavailable on the hosted endpoint — connection timeout or 5xx error
- Empty or malformed topic override parameter — procedure may default to generic recommendation context

## How this service works

Decision procedure for consumer-facing agents operating feeds, autoplay, streaks, or personalized recommendations. Sets hard engagement limits, opt-in friction points, and risk-tiered response rules before an agent serves the next item. Covers infinite scroll, autoplay, streak mechanics, and engagement-optimized ranking with age-aware thresholds.

## Output

A structured decision procedure brief including: hard engagement limits, required opt-in friction points, risk-tiered response rules by scenario (infinite scroll, autoplay, streak mechanics, engagement-optimized ranking), and age-aware thresholds — returned as prose and/or structured fields with a generation timestamp and source type.
