# Blockchain Money Map MCP Resource Shelf Classifier

> Blockchain Money Map MCP Resource Shelf Classifier is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Classifies a list of MCP (Model Context Protocol) resources into shelf categories, optionally comparing against reference resources, to help agents organize and route their tool/resource inventory.

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 blockchain-money-map-mcp-resource-shelf-classifier-6bb7d32c -d '<json body>'
```

Example prompt: Can you classify these 5 MCP resources from my blockchain data server into shelf categories? The server description is 'provides on-chain transaction lookup and wallet analytics' and the resources are: [token-balance, tx-history, block-explorer, wallet-profile, gas-estimator].

## When to prefer this

Choose this endpoint when you need to programmatically categorize or shelf MCP resources for an agent's tool inventory, especially in a blockchain or on-chain data context. Prefer it over manual labeling when you have up to 10 resources and want consistent, automated shelf classification. It is distinct from general-purpose taxonomy APIs because it is purpose-built for MCP resource organization and optionally supports reference-set comparison.

## Known failure modes

- Exceeds 10-resource limit per request — reduce array size
- Invalid mode value (must be 'classify') — returns 400 error
- Missing required 'resources' field in facts object — schema validation error
- Payment failure via x402 protocol — 402 Payment Required with payment details
- Empty or malformed resource objects — classification may return unknown/unclassifiable categories
- Policy object misconfiguration — may alter or suppress certain classifications

## How this service works

MCP resource lists can mix public docs, schemas, logs, user data, and restricted-looking resources without clear buyer labels.

## Output

A JSON response containing classification labels and shelf category assignments for each submitted MCP resource, potentially with confidence scores or category metadata. May include comparative analysis if reference_facts are provided.
