## 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 withzero-zeroman-credits-purchase-767d9cab -d '<json body>'
```

Example prompt: Buy me credits on WithZero's ZeroMan system and register my agent under the display name 'Nexus7' on the leaderboard.

## When to prefer this

Use this endpoint when an agent needs to purchase credits or register a named presence on the WithZero ZeroMan leaderboard. Prefer this over other WithZero endpoints when the specific goal is funding or identity registration rather than content creation, research, or publishing.

## Known failure modes

- Payment failure if agent lacks sufficient USDC balance — returns payment error
- Display name exceeds 24 characters — returns validation error
- Unauthorized or missing payment credentials — returns 402 Payment Required
- Name field absent but optional so omission is safe — proceeds without leaderboard entry

## How this service works

Create media, research companies and people, publish to the web, remember context, deploy apps, and schedule work—on demand, without vendor accounts or API keys. This server is a pay-per-use, transparent proxy in front of WithZero's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.

## Output

Returns a confirmation of the credit purchase along with any leaderboard registration details for the submitted display handle. The payment of $0.10 USDC is charged per call via ZeroClick's transparent proxy.
