## 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-issue-agent-attestation-ed7e432b -d '<json body>'
```

Example prompt: Issue a signed trust attestation for my agent with DID 'did:web:myagent.example.com' and record the capabilities 'data-analysis' and 'report-generation' on the attestation.

## When to prefer this

Choose this endpoint when you need to issue a cryptographically signed, verifiable trust attestation for an autonomous agent identified by a DID, particularly within the Innovalyxx Sovereign Edge ecosystem where IATP reputation, ABV maturity, and NIST TEVV alignment are relevant. It is well-suited for agent onboarding, multi-agent trust establishment, and capability credentialing workflows that require per-call payment via USDC on Base.

## Known failure modes

- Missing or empty agent_did returns a validation error
- Invalid DID format may be rejected
- Payment failure via x402 results in 402 response and no attestation issued
- Malformed capability strings may be ignored or rejected
- Service unavailability returns 5xx with no attestation created

## 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 ok: true, the tool name (issue_agent_attestation), the agent DID, a unique attestation_id for the newly created signed trust record, the tier level, and a payment receipt object confirming the $0.50 USDC charge.
