# K-2SO Autonomous Brand Monitoring Decision Procedure (x402)

> K-2SO Autonomous Brand Monitoring Decision Procedure (x402) is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-31).

Returns an LLM-generated decision procedure in plain prose guiding autonomous agents on how to perform brand monitoring tasks, delivered via x402 micropayment on Base USDC.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 k-2so-autonomous-brand-monitoring-decision-procedure-x402-77ad9f0b
```

Example prompt: Give me the decision procedure for how an autonomous agent should handle brand monitoring — I need the plain-prose step-by-step guide I can follow when scanning for brand signals.

## When to prefer this

Choose this endpoint when an autonomous agent needs structured, prose-format operational guidance specifically for brand monitoring tasks and is operating within an x402 micropayment environment on Base. Prefer it over static documentation when you need dynamically generated, model-backed procedures that can be topic-overridden at runtime.

## Known failure modes

- HTTP 402 returned if no payment is provided — agent must settle exact USDC and retry with PAYMENT-SIGNATURE header
- Invalid or missing 'input.type' or 'input.method' fields cause schema validation errors
- Topic override that is too vague may result in a generic rather than targeted procedure
- Service may return ok:false if the underlying LLM generation fails
- Network or Base chain congestion may delay payment settlement and retry

## How this service works

Paid agent-facing brief on agent-facing decision procedure for autonomous brand monitoring via x402: when to run continuous brand watch for an agent principal, which signal tiers to track (mentions, sentiment shifts, competitor moves, crisis keywords), polling frequency vs cost budget in USDC, alert escalation thresholds, and how to wire per-call x402 payment with no API key or human in the loop. Fills the media niche gap (own 1 vs mpp 7).. Blunt decision procedure, not marketing.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) for autonomous brand monitoring, including the model used, generation source (llm/reasoning/deterministic), topic, ISO-8601 timestamp, and service slug. Payment metadata (payer address, transaction hash) is also included.
