## 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 semantic-hash-indexer-mcp-309af5e2 -d '<json body>'
```

Example prompt: Can you generate a semantic hash index for this text so I can detect duplicates and enable fast similarity lookups: 'Artificial intelligence is transforming the way we interact with software systems'?

## When to prefer this

Choose this endpoint when you need to generate semantic hash fingerprints for text content to support deduplication, similarity search, or semantic caching workflows. It is particularly useful in agentic pipelines where repeated or near-duplicate content must be detected efficiently before expensive downstream processing.

## Known failure modes

- Empty or missing 'data' field returns a validation error
- Extremely long input strings may exceed payload limits
- Malformed JSON body results in a 400 bad request
- Service unavailability returns 402 or 5xx error
- Non-UTF-8 encoded strings may fail to process correctly

## 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 a semantic hash or index representation of the input text, which can be used as a fingerprint for similarity comparison, deduplication checks, or fast retrieval in a vector or hash-based index store.

## Response schema (JSON Schema)
