# K-2SO Merchant Crawler Traffic Gating and Pricing Decision Procedure

> K-2SO Merchant Crawler Traffic Gating and Pricing Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-17).

Returns a paid LLM-generated or deterministic decision procedure (prose brief) for how an agent should gate and price merchant crawler traffic via the x402 protocol

## 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-merchant-crawler-traffic-gating-and-pricing-decision-procedure-8e84a092
```

Example prompt: What is the decision procedure for gating and pricing merchant crawler traffic on my x402 agent API — give me the full prose brief so I can implement the logic?

## When to prefer this

Choose this endpoint when an AI agent needs a ready-made, prose-formatted decision procedure specifically for evaluating and pricing merchant crawler traffic in an x402 agent-to-agent payment context. It is ideal when the agent lacks internal policy logic for traffic gating or needs an authoritative external brief to bootstrap its pricing decisions. Prefer this over generic API pricing guides when operating on the Base network with USDC and x402 payment flows.

## Known failure modes

- HTTP 402 returned if payment has not been settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing method enum value causes schema validation error
- Network or provider unavailability returns non-200 response
- LLM generation failure may fall back to deterministic procedure source
- Incorrect topic override may produce off-domain procedure text

## How this service works

Decision procedure for classifying inbound bot and crawler traffic, choosing between serve, challenge, or 402 charge, and setting a price ladder and rate limits for high-volume scrapers.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) for merchant crawler traffic gating and pricing, along with the topic, model used, generation source (llm, reasoning, or deterministic), ISO-8601 timestamp, and service slug. The 'brief' and 'procedure' fields contain the actionable guidance an agent can directly use to implement gating and pricing logic.
