## 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-pricing-hint-99999822 -d '<json body>'
```

Example prompt: Before I run the verify_biodiversity tool for entity 'proj-carbon-001', can you get a pricing hint using my wallet 0xAbCd1234567890AbCd1234567890AbCd12345678 to see what the suggested price and discount factor would be?

## When to prefer this

Use this endpoint when an AI agent or autonomous workflow needs a non-binding cost advisory before committing to a paid Innovalyxx verification tool call, especially to check for usage-based discounts, compare list vs. suggested price, or log hint hashes for audit trails. Prefer this over direct tool invocation when budget planning, discount eligibility checks, or pre-authorization workflows are required.

## Known failure modes

- Invalid or malformed owner_wallet (not exactly 42 characters or not 0x-prefixed) returns a validation error
- Missing or invalid wallet_signature causes signature recovery failure and an authentication error
- Unknown or misspelled tool_name may return a null or zero price hint with no recommended action
- Missing entity_id results in a schema validation error
- Payment via x402 not completed results in a 402 Payment Required response before the hint is returned
- Rate limiting or transient server errors may return 5xx responses

## Output

A JSON object indicating whether the request succeeded, the tool name, entity ID, owner wallet, list price in USD, discount factor, suggested price in USD, prior invocation count, a recommended action string, a hint hash for audit purposes, an issued_at timestamp, and flags indicating the response is metadata-only and non-binding.
