## 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 m2mcent-nft-metadata-generator-mcp-f4b85f00 -d '<json body>'
```

Example prompt: Generate NFT metadata for a cyberpunk samurai warrior with glowing neon armor and a katana — I need the metadata URL back so I can use it for minting.

## When to prefer this

Choose this endpoint when you need to programmatically generate NFT metadata from a natural language description and receive a hosted metadata URL ready for on-chain use, especially within the M2MCent MCP ecosystem using x402 micropayment settlements on Base L2. Prefer this over manual metadata creation tools when you need fast, agent-driven NFT metadata generation at $0.20 USDC per call.

## Known failure modes

- Missing required 'prompt' field returns a 400 validation error
- Payment failure (insufficient USDC or x402 protocol error) returns 402 Payment Required
- Malformed prompt or overly long input may result in generation errors
- Network or node availability issues on the M2MCent infrastructure may cause 503 errors
- The metadataUrl field typed as boolean in the schema suggests a possible schema documentation error — actual URL string may be returned

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns an object containing a metadataUrl field (typed as boolean in the schema, but functionally a URL string pointing to the generated NFT metadata resource). The agent can use this URL when minting or registering the NFT on-chain.
