## 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-memory-grant-efaeff2d -d '<json body>'
```

Example prompt: Grant wallet 0xAbCdEf1234567890AbCdEf1234567890AbCdEf12 read access to the 'verification' and 'context' memory categories for project entity proj_42, valid until 2026-01-01, signed by my owner wallet 0x1234567890AbCdEf1234567890AbCdEf12345678 with my EIP-191 signature.

## When to prefer this

Use this endpoint when an autonomous agent needs to formally delegate, with cryptographic audit trail, read access to specific memory categories of an entity to another wallet or agent. It is the right choice when consent provenance, expiry control, and DID binding are required — for example in multi-agent workflows, habitat monitoring, MRV verification chains, or cross-organization data sharing where a consent_hash and grant_id must be recorded on-chain or in audit logs.

## Known failure modes

- Invalid or mismatched EIP-191 signature returns an authorization error
- Grantor wallet does not own the entity's memory, returning a forbidden error
- Grantee or grantor wallet address is not exactly 42 characters (0x + 40 hex) returns a validation error
- Empty or invalid categories array returns a schema validation error
- expires_at more than 730 days in the future is rejected
- Payment not satisfied via x402/USDC returns a 402 Payment Required response
- Unknown entity_type enum value returns a 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 confirming the grant was created, including a unique grant_id, a consent_hash for audit purposes, the granted_at and expires_at timestamps, the grantee and grantor wallet addresses, and the list of authorized memory categories.
