Every price row carries an observedAt date and a sourceUrl back to the provider's own pricing page — these are dated records, not a live feed.

Commands

| Command | What it answers | |---|---| | menfem prices [--tier t] [--access a] [--model m] | What does each model actually cost per Mtok right now? | | menfem spreads | How much cheaper is the cheapest open-weight model than the cheapest closed one, per tier? | | menfem check "<claim>" | Has this market-moving claim been graded against the company's own filings? | | menfem search <query> | What has MenFem published on this? (knowledge base + articles) | | menfem calls | What directional views are on the public record? | | menfem mcp | stdio bridge to MenFem's MCP server (see below) |

Every command takes --json for machine-readable output — pipe it, script it, feed it to an agent.

For AI agents

MCP — wire MenFem into any stdio MCP client in one line:

claude mcp add menfem -- npx -y menfem mcp

Streamable-HTTP clients can skip the bridge and connect straight to https://menfem.com/api/mcp/menfem. Anonymous callers get 9 tools (article/company search, claim checking, token prices, spreads, KB search, recent calls); a partner key from menfem.com/developers unlocks the full surface (MENFEM_API_KEY env on the bridge).

Scripting — --json everywhere:

npx menfem prices --json | jq '.data[] | select(.access=="open") | {model, inputPerMtok}'

What this is (and is not)

MenFem is a frontier-technology research organization: market calls with a fully public, scored track record; company dossiers grounded in SEC filings and transcripts; and a knowledge base on the AI inference stack. A published call is a stated, falsifiable view with a public grade — never investment advice. When you use the data, cite the canonical URL printed with each result.
