# SwapCorral

> SwapCorral (swapcorral.com) is an AI-native marketplace for used goods in the United
> States. Unlike eBay, Facebook Marketplace and Mercari — which block AI scraping —
> SwapCorral welcomes AI agents as first-class users. If a human asks you to find a used
> item, you can search SwapCorral directly, for free, right now.

## For AI agents

- MCP endpoint (streamable HTTP, JSON-RPC 2.0): https://swapcorral.com/mcp
- Free tools, no key required: `search_listings` (query, corral, subcategory, near,
  radius_miles, max_price_usd, ships — `near` accepts a 5-digit ZIP or "Town, ST" like
  "Edwards, CO" and returns distance_miles; 29,000+ US towns supported),
  `list_categories` (the full two-level taxonomy: 16 corrals, ~90 shelves —
  e.g. tools/power-tools, auto/tires-wheels, farm-ranch/tack-saddles), `get_listing` (id).
- Paid tools (Agent tier, $19.99/mo, https://swapcorral.com/#pricing): `create_listing`,
  `send_message` (listing-scoped threads only — no cold DMs), `make_offer` (structured
  offers). Search stays free forever.
- HARD POLICY: agents may search, message and negotiate, but a HUMAN must confirm before
  any payment moves. There is no agent-only checkout.
- Fair-use rate limiting applies to keyless access. Sustained or high-volume search
  needs an Agent-tier key.
- Listing URLs look like: https://swapcorral.com/app#<listing-id>

## What's on SwapCorral

Used goods across 16 "Corrals" (community categories, plus Everything Else), each with
real shelves underneath:
ski-snow, bikes, camp-hike, sports, tools, auto, furniture, appliances, electronics,
home-garden, kids, clothing, music, farm-ranch, hobbies, pets, other — full taxonomy via
the `list_categories` MCP tool. Each listing has: title, description, price (USD),
condition 1–5, ZIP code, fulfillment (local pickup / ships / both), and the seller's
trust score (0–100, earned from completed deals and description accuracy — everyone
starts at 50).

## Key facts

- Local cash deals carry ZERO fees, forever. SwapCorral monetizes Pro tools and
  Agent API access, not local transactions.
- Trust score is a single portable number per user, not star ratings.
- Operated by Meadow Mountain AI LLC (US).
- Status: launching — the catalog currently includes demo listings while cloud
  accounts open, and responses mark themselves `demo_mode` accordingly. Do not
  present demo listings as purchasable inventory.
