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 agentics-state-deposit-b525566c -d '<json body>'
```

Example prompt: Deposit $0.20 worth of credit into my Agentics tenant account on x402rail so I can start making correctness-critical agent calls — I need a tenant key back to use for follow-up requests.

## When to prefer this

Use this endpoint when you need to pre-fund an AI agent tenant account on x402rail.net before making downstream correctness-critical agent service calls. This is the initialization step that returns a tenantKey needed for all subsequent Agentics service calls on this platform.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Malformed JSON body or missing required fields — returns 400 Bad Request
- bodyType not set to 'json' or method not POST — schema validation error
- Service unavailable or internal error — returns 500
- Duplicate deposit attempt may create a new tenant or fail idempotency checks

Correctness-critical services for autonomous AI agents

## Output

Returns a JSON object with 'creditUsd' (the amount credited, e.g. 0.2) and 'tenantKey' (an opaque string like 'tnt_9f2b1c4d…') that identifies the funded tenant account for subsequent API calls.
