## 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 innovalyxx-sovereign-edge-verify-agent-trust-97e8684d -d '<json body>'
```

Example prompt: Can you verify the trust score for the agent with DID 'urn:aid:innovalyxx:sovereign-edge' in the MRV verification context and tell me whether it's fully verified?

## When to prefer this

Choose this endpoint when you need cryptographically-grounded trust scoring for a DID-based AI agent before granting it access to sensitive protocols, data pipelines, or MRV workflows. It is purpose-built for the Innovalyxx KYA-OS URN namespace and returns a structured tier + numeric trust score, making it preferable to generic identity checks when operating within sovereign edge or cyber-physical agent ecosystems where per-call micropayment accountability (x402/USDC) is required.

## Known failure modes

- Invalid or malformed agent DID format returns a validation error
- Unknown DID not registered on the network returns verified: false with trust_score: 0
- Missing required agent_did field returns a 400 bad request
- x402 payment failure (insufficient USDC balance) results in 402 Payment Required and no verification
- Network or upstream DID resolution failure may return a 500 error

## How this service works

Verified cyber-physical AI tools for autonomous agents. Pay per call via x402 (USDC on Base). 26 tools covering MRV verification, biodiversity, skip twin, site certification, agent trust, transaction evidence, protocol bridging, GEO audit, IATP reputation, ABV maturity, NIST TEVV alignment, and encrypted memory write/read/query/grant/revoke/tool_context/pricing_hint/subscription_quote/attest/verify_attestation.

## Output

Returns a JSON object indicating whether the agent DID is verified (boolean), the numeric trust score, the agent's tier classification, the tool name, and a payment receipt object confirming the $0.01 USDC x402 payment processed on Base.
