x402
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.

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.
Example use cases
Pre-integration autonomy audit
“Before I wire up my agent to this x402 payment service, can you run the servability grading playbook on it and check whether it has a real x402 contract, passes MCP compatibility, and has no hidden human throughput limits?”
Detecting human-mediated facades
“I think this API claiming to be fully autonomous might actually have humans reviewing requests behind the scenes — can you grade its counterparty servability and give me the evidence tuple on API surface, response determinism, and human throughput constraints?”
Comparing x402 service trustworthiness
“My agent needs to pick between two x402 services for recurring payments — can you run the servability grading playbook on the counterparty and tell me if it's a genuine machine-servable endpoint or just a facade dressed up as one?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/counterparty-autonomy-servability-grading-playbo?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
