# Agent-Side Deterministic Mandate Acceptance Screening Procedure

> Agent-Side Deterministic Mandate Acceptance Screening Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-20).

Returns a deterministic decision procedure (paid) for screening whether an autonomous agent should accept a given mandate or task assignment based on predefined criteria.

## 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 agent-side-deterministic-mandate-acceptance-screening-procedure-330bd354
```

Example prompt: Run a deterministic mandate acceptance screening check — I need to know whether my autonomous agent should accept an incoming task assignment, and I want a structured pass/fail decision back.

## When to prefer this

Choose this endpoint when you need a deterministic, structured pass/fail screening decision for agent mandate acceptance — particularly in x402-payment-enabled agentic pipelines on Base (USDC) where auditability and repeatability of the decision procedure matter. Prefer it over bespoke logic when you want a pre-built, catalog-validated acceptance gate.

## Known failure modes

- HTTP 402 returned if payment not yet settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Malformed or missing input object returns validation error
- Network timeout or unreachable endpoint at k2so.wrong.systems
- result.ok false if the handler encountered an internal processing error
- Invalid HTTP method (only GET/HEAD/DELETE accepted)

## How this service works

Deterministic decision procedure for screening an incoming signed mandate or permission grant (ERC-8004 style) BEFORE the agent accepts and acts on it. Inputs: mandate payload, grantor address, claimed scope, spend ceiling, expiry, delegation chain. Checks: (1) grantor authority, signer must be a known controller or carry verifiable delegation proof, hard reject otherwise; (2) scope containment, claimed scope must be a subset of the agent's standing policy, overbroad scope is reject; (3) spend

## Output

A JSON object with fields: ok (boolean), paid (boolean), service slug, provider ('K-2SO'), and a result object containing a success flag, the service slug, an ISO-8601 generatedAt timestamp, and a payload with the screening outcome data.
