# Agent Authorization Mandate Verification and Identity Credential Decision Brief

> Agent Authorization Mandate Verification and Identity Credential Decision Brief is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns a paid, LLM-generated decision procedure brief for agents evaluating whether to honor or accept a payment from another agent claiming authorization via signed mandates, key binding, scope/expiry/spend caps, and identity credentials.

## 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-authorization-mandate-verification-and-identity-credential-07abddfe
```

Example prompt: Give me a blunt decision procedure brief on how to verify another agent's authorization mandate and identity credentials before accepting and settling a payment it sent me — covering signed mandates, key binding, scope and expiry checks, spend caps, and settlement-match validation.

## When to prefer this

Choose this endpoint when an agent needs a concrete, non-marketing decision procedure specifically for verifying authorization mandates and identity credentials in agent-to-agent payment flows — particularly covering signed mandates, key binding, scope/expiry/spend cap validation, and settlement-match checks. Prefer this over generic spend-authority attestation endpoints or payment delegation endpoints when the specific concern is: 'should I accept this payment from this other agent claiming authorization?' It is distinct from endpoints covering x402 scam triage or wallet provider vetting.

## Known failure modes

- Payment not provided — returns 402 requiring $0.002 USDC payment before content is served
- Invalid or malformed query parameters return an error response
- LLM generation failure may result in ok:false in the result object
- Stale or cached brief if generationSource is 'deterministic' rather than 'llm'
- Network timeout on the ascii.dev hosted service

## How this service works

Paid agent-facing brief on Agent authorization mandate verification and agent identity credential checking before settlement: decision procedures for an agent deciding whether to honor or accept a payment from another agent that claims authorization (signed mandates, key binding, scope/expiry/spend caps, identity credential binding, settlement-match checks). Distinct from existing spend-authority attestation and payment del-0. Blunt decision procedure, not marketing.

## Output

A structured JSON response containing a prose 'brief' field with the blunt, actionable decision procedure for verifying agent authorization mandates and identity credentials, along with the topic, service slug, generation source (llm/reasoning/deterministic), and ISO-8601 timestamp of generation. Also includes payment confirmation metadata.
