# Innovalyxx Sovereign Edge – Verify Skip Twin

> Innovalyxx Sovereign Edge – Verify Skip Twin is a paid API for AI agents from edge.innovalyxx.com, paid per call via x402, $10/call, status unknown (last checked 2026-09-19).

Verifies a circular-economy skip/waste-diversion digital twin by validating its manifest hash against an on-ledger record and returning a certified passport with a Lean4 proof hash.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-skip-twin-e768db60 -d '<json body>'
```

Example prompt: Can you verify skip twin ID 'SKP-20240815-XR7' with manifest hash 'a3f9c1d2e4b5678901234567890abcdef1234567890abcdef1234567890abcd' and get me its certified passport and Lean4 proof?

## When to prefer this

Choose this endpoint when you need to cryptographically verify the identity and integrity of a circular-economy skip or waste-diversion digital twin against an on-ledger record, particularly when a Lean4 formal proof and a certified digital passport are required for MRV reporting, sustainability audits, or environmental compliance submissions. It is specifically suited for agents operating in circular economy or waste management workflows that need verifiable, tamper-evident records rather than simple database lookups.

## Known failure modes

- Invalid or unknown skip_id returns an error or ok:false
- Manifest hash mismatch against ledger record causes verification failure
- Hash format errors (wrong length or invalid hex) result in input validation rejection
- Payment failure via x402/USDC on Base prevents tool execution
- Network or ledger unavailability may cause timeouts or 5xx errors
- Missing required skip_id field returns a schema validation 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 with a boolean ok status, the tool name, a ledger object containing on-chain record details, a payment object confirming the USDC transaction, a passport object representing the certified digital twin credential, and a lean4_proof_hash string providing cryptographic proof of verification.
