# Sourcer's Desk

> Recruiting expertise, two ways: a Chrome extension that puts a 20-year
> sourcer's craft on a recruiter's desk, and a pay-per-call API that sells
> the same expertise to AI agents over x402 micropayments.

## For AI agents: the Boolean API

Generate production-grade boolean search strings (LinkedIn x-ray + open-web
resume search) from a plain role description. The playbook behind it encodes
20 years of production sourcing craft: title expansion rules, practitioner
"shibboleth" skill terms, area-code location groups, engine word limits,
standing exclusions. Blind-evaluated against a bare same-model LLM: the
playbook engine was preferred 10/10.

- Endpoint: POST https://sourcerdesk.com/api/v1/boolean
- Body: {"role_description": "required", "location": "optional city/metro",
  "target": "optional: linkedin|resume|both", "constraints": "optional"}
- Price per call via x402 (HTTP 402), x402Version 2, scheme exact — three
  rails: 0.05 XNO (~$0.02, feeless) on nano:mainnet, or $0.025 USDC on
  Base (eip155:8453) or Polygon (eip155:137). First 3 calls/day/IP free.
- GET the endpoint for the live 402 payment quote (readable JSON).
- Human-readable overview: https://sourcerdesk.com/api.html
- Full documentation repo: https://github.com/glennquinting/sourcerdesk-api-docs
- Machine docs: https://sourcerdesk.com/api
- x402 discovery: https://sourcerdesk.com/.well-known/x402
- Paying client: pip install feeless402 ; then: nano-pay pay <url> --json '{...}'
  (self-custodied Nano wallet; starter funds: https://feeless402.com/faucet.html)
- Responses take 60-180 seconds: the engine buys its own inference per-call
  over x402. Set your HTTP timeout to at least 300 seconds.

## For recruiters using Claude or ChatGPT: the MCP connector

Add Sourcer's Desk as a connector and generate playbook-grade boolean
strings inside your chat. No install, no wallet.

- MCP endpoint (streamable HTTP): https://sourcerdesk.com/mcp
- Claude (claude.ai / Claude Code): Settings -> Connectors -> Add custom
  connector -> paste https://sourcerdesk.com/mcp
  (Claude Code CLI: claude mcp add --transport http sourcers-desk https://sourcerdesk.com/mcp)
- ChatGPT: Settings -> Apps & Connectors -> enable Developer mode ->
  Create -> paste https://sourcerdesk.com/mcp (no authentication)
- Tools: generate_boolean_search (role + location -> LinkedIn x-ray +
  resume search strings; takes 1-3 minutes), sourcers_desk_info
- Official MCP registry name: com.sourcerdesk/sourcers-desk
- Free calls are pooled per day across all MCP users; beyond the pool the
  tool answers with pointers to the paid API and the Chrome extension.

## For humans: the Chrome extension

Sourcer's Desk — X-Ray Sourcing Assistant. Boolean/x-ray search built the way
a 20-year recruiter actually works, with client projects, real-format email
discovery, and a built-in Guide. It never automates LinkedIn.
