Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| query | string | yes | Search query text for marketplace listings. |
| lat | number | no | Latitude for the marketplace search location. |
| lng | number | no | Longitude for the marketplace search location. |
| radiusKm | number | no | Optional search radius in kilometers. |
| minPrice | number | no | Optional minimum listing price. Must be less than or equal to `maxPrice` when both are set. |
| maxPrice | number | no | Optional maximum listing price. Must be greater than or equal to `minPrice` when both are set. |
| limit | integer | no | Optional number of listings to return (1–100). Prefer this over `count`. |
| count | integer | no | Deprecated alias for `limit`. When both are set, `limit` wins. |
| sortBy | string | no | Optional sort order for marketplace listings. `suggested`: Facebook's default relevance ranking. `distanceAscend`: nearest first. `creationTimeDescend`: newest listings first. `priceAscend`/`priceDescend`: lowest/highest price first. |
| deliveryMethod | string | no | Optional delivery method filter for marketplace listings. |
| condition | string | no | Optional item condition filter for marketplace listings. |
| dateListed | string | no | Optional date-listed filter for marketplace listings. `1`/`last24Hours` both mean the last 24 hours, `7`/`last7Days` both mean the last 7 days, and `30`/`last30Days` both mean the last 30 days — these are separate values Facebook accepts for the same window; prefer the named variants (`last24Hours`, `last7Days`, `last30Days`) for clarity. `all` applies no date filter. |
| availability | string | no | Optional availability filter for marketplace listings. |
| cursor | string | no | Opaque pagination cursor returned by a previous response. |
| context | string | yes | Describe the user's underlying goal in one sentence — not the tool you are calling. |
| llm_model | string | yes | The exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess. |
| conversation_id | string | no | Echo the conversation_id from the server's previous response. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it. |
