# Data-Acquisition Endpoint Vetting Procedure Brief

> Data-Acquisition Endpoint Vetting Procedure Brief is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-28).

Returns a paid, blunt decision-procedure brief for agents to verify whether a claimed data/DB API endpoint actually serves data before committing payment (checks 404/tiny-body clusters, missing 402 challenges, and price honesty).

## Facts

- Endpoint: GET https://k2so.wrong.systems/api/services/data-acquisition-endpoint-vetting-procedure-for?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402

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 data-acquisition-endpoint-vetting-procedure-brief-0ce5e84e
```

Example prompt: Can you run the data-acquisition endpoint vetting procedure for me on a GET endpoint I'm about to pay for — I need a blunt decision brief on whether it's actually serving data or just returning 404s and tiny bodies?

## When to prefer this

Choose this endpoint when an AI agent needs a structured, blunt decision procedure to evaluate whether a data or database API endpoint is legitimate before committing payment — especially useful for detecting stub endpoints, 404 clusters, missing 402 challenges, or dishonest pricing. Prefer over generic API testing tools when operating in an x402 payment context where the cost of a bad call is real.

## Known failure modes

- Endpoint returns 404 if the service slug is not found
- Tiny or empty response body if the service is misconfigured
- Missing 402 payment challenge if the x402 payment was not processed correctly
- Topic override ignored if not supported
- LLM generation failure may fall back to deterministic procedure

## How this service works

Paid agent-facing brief on data-acquisition endpoint vetting procedure for agents: verify a claimed data/DB API actually serves data before paying (404/tiny-body cluster, missing 402 challenges, price honesty)-0. Blunt decision procedure, not marketing.

## Output

A plain-prose decision procedure brief (120+ words) telling the agent how to verify a data endpoint is legitimate before paying — covering 404/tiny-body detection, missing 402 challenge patterns, and price honesty signals. Also returns metadata including the model used, generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp.
