# Molecular Patent Search MCP

> Molecular Patent Search MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.3/call, status unknown (last checked 2026-09-15).

Searches molecular and chemistry-related patent databases to retrieve patent information for a given molecule or chemical query.

## Facts

- Endpoint: POST https://api.m2mcent.com/molecular-patent-search-mcp/api/process
- Price: $0.3/call
- Payment: x402
- Status: unknown

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 molecular-patent-search-mcp-2b79aa09 -d '<json body>'
```

Example prompt: Search for existing patents related to the molecule aspirin (acetylsalicylic acid) and tell me what patents are on record, who filed them, and when.

## When to prefer this

Use this endpoint when you need to search patent databases specifically for molecular or chemical compound information, such as during drug discovery, freedom-to-operate analysis, or competitive IP research. Prefer this over general patent search tools when the query is chemistry-specific and involves molecular structures, SMILES notation, or pharmaceutical compounds.

## Known failure modes

- Molecule identifier not recognized or malformed SMILES string returns no results
- Patent database unavailable or timeout returns error
- Ambiguous compound name matches multiple molecules leading to broad results
- Query string too vague returns unrelated patents
- Payment not processed leads to 402 response blocking the request

## 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 collection of patent records matching the molecular or chemical query, including patent numbers, titles, filing dates, inventors, assignees, and relevant chemical structure matches found in patent databases.
