# Blockchain Money Map ASO Grader – Agent Discovery Snippet Checker

> Blockchain Money Map ASO Grader – Agent Discovery Snippet Checker is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Grades and validates agent-service discovery snippets for quality and discoverability using a reference-based 'check' mode evaluation.

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-aso-grader-agent-discovery-snippet-checker-38df694b -d '<json body>'
```

Example prompt: Check my agent discovery snippets for quality — here are the snippets I want graded: ['Blockchain data API for fund flows', 'Real-time on-chain analytics']. Use check mode and compare them against my reference snippets: ['Best-in-class on-chain money flow tracker'].

## When to prefer this

Choose this endpoint when you need to programmatically evaluate and score agent-service discovery snippets for quality and discoverability before publishing to agent marketplaces or x402 directories. Particularly useful for API publishers optimizing their listing metadata for agent-driven discovery (ASO). Not suited for general blockchain data queries or human-readable report generation.

## Known failure modes

- Missing required discoverySnippets array returns validation error
- Empty snippets array may produce low-confidence or degenerate scores
- Snippets exceeding maxItems:10 are truncated or rejected
- Malformed JSON input returns 400-level error
- Payment failure via x402 protocol blocks request execution
- mode field must be 'check' — other values are rejected

## How this service works

Public discovery snippets often fail to state who the agent serves, what it does, what it costs, what proof it returns, and what it does not do.

## Output

A JSON response containing a graded evaluation of the submitted discovery snippets, potentially including quality scores, comparison against reference snippets, and recommendations for improving agent-service discoverability and ASO performance.
