# Innovalyxx Sovereign Edge – Verify Agent Attestation

> Innovalyxx Sovereign Edge – Verify Agent Attestation is a paid API for AI agents from edge.innovalyxx.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-19).

Cryptographically verifies an IATP Ed25519 attestation envelope for an AI agent, confirming the attestation is valid and optionally checking it against a specific agent DID.

## 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-attestation-6c1a2606 -d '<json body>'
```

Example prompt: Can you verify this IATP Ed25519 attestation envelope for my agent — the agent DID is did:peer:0z6Mk... — and tell me whether the attestation is valid before I let it execute any transactions?

## When to prefer this

Choose this endpoint when you need to cryptographically verify an IATP Ed25519 agent attestation in an autonomous agent pipeline, especially when operating in a zero-trust cyber-physical environment where fail-closed validation is required. It is particularly suited for multi-agent orchestration scenarios where agent identity must be confirmed before granting access or executing consequential actions. Prefer this over generic signature verification tools when you need IATP-protocol-aware validation with integrated x402 micropayment support.

## Known failure modes

- Invalid or malformed Ed25519 attestation envelope returns valid:false with an error message
- agent_did provided does not match the agent_id in the attestation, returning a fail-closed error
- Missing required 'attestation' field causes a validation error
- Expired or revoked attestation returns valid:false
- x402 payment failure (insufficient USDC) prevents the call from being processed
- Network or service unavailability returns a non-200 response

## 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

A JSON object containing: 'valid' (boolean indicating whether the attestation passed verification), 'agent_id' (the agent identity extracted from the attestation), 'ok' (overall success flag), 'tool' (name of the tool called), 'payment' (x402 payment metadata), and 'error' (error message string if verification failed).
