# Counterparty Autonomy Servability Grading Playbook

> Counterparty Autonomy Servability Grading Playbook is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-13).

Classifies whether an x402 agent-facing service is genuinely machine-servable end-to-end or a human-mediated facade, producing a structured servability verdict with evidence.

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 counterparty-autonomy-servability-grading-playbook-a2a8137d
```

Example prompt: Can you run the counterparty autonomy servability grading playbook on this x402 service and tell me if it's genuinely machine-servable end-to-end, or if there's a human somewhere in the loop?

## When to prefer this

Use this endpoint when an AI agent needs to vet a third-party x402 service before integrating it into an autonomous workflow — specifically to confirm that no human is silently mediating responses, that an x402 payment contract is genuinely present, and that the service is MCP-compatible and deterministic enough for autonomous use. Prefer this over generic API auditing tools when the concern is specifically about agentic autonomy, x402 compliance, and machine-to-machine servability.

## Known failure modes

- Service slug not found or unrecognized — returns error in result.ok=false
- Payment not completed — returns unpaid response without the verdict
- LLM or reasoning backend unavailable — generationSource may fall back or fail
- Topic override not applicable to the service — may return generic procedure
- Network timeout to upstream provider k2so.wrong.systems

## How this service works

Classifies whether an agent-facing x402 service is genuinely machine-servable end to end or a human-mediated facade. Produces a servability verdict with an evidence tuple covering API surface, x402 contract presence, MCP compatibility, response determinism, and human throughput constraints.

## Output

A servability verdict object indicating whether the service is genuinely machine-servable, along with an evidence tuple covering: API surface quality, x402 contract presence, MCP compatibility, response determinism, and human throughput constraints. Also includes a prose decision procedure brief, generation metadata (timestamp, model, source), and payment confirmation.
