Latest Prediction Market Activity

Latest Market Activity

FinFeedAPI provides a standardized API for retrieving recent trading activity from supported prediction market exchanges.

Access recent trades and quote updates for a selected market_id through one consistent response model. The endpoint returns batches of market events rather than only identifying which markets have activity, making it suitable for monitoring recent price changes, executed transactions, bid and ask updates, and available quoted volume.

What Is Latest Prediction Market Activity?

Latest prediction market activity is a recent batch of trades and quotes associated with a specific prediction market.

Trades describe executed transactions. Each trade includes the market identifier, execution price, quantity, timestamp, outcome, and trade side.

Quotes describe recent bid and ask updates. Each quote includes its entry and receipt timestamps, bid and ask prices, and the available volume associated with both sides.

Together, these records show what has recently happened inside a market rather than only indicating that the market has been active.

Why Use Latest Market Activity?

The Latest Market Activity endpoint returns a recent batch of market events for one prediction market. This makes it useful for examining short-term price movement, recent transaction flow, quote changes, and the sequence of market updates without retrieving flat-file history.

Developers commonly use latest market activity to:

inspect recent trades for a selected market
retrieve recent bid and ask updates
monitor short-term market activity
analyze recent transaction prices and quantities
compare recent executed trades with quoted prices
populate market activity feeds

What's Included in Latest Market Activity?

The response contains two collections: trades and quotes. These fields provide both executed transaction data and quoted market conditions in one response.

Trade Fields

Field	Description
id	Identifier assigned to the trade.
market_id	Canonical identifier of the prediction market outcome.
price	Price at which the transaction occurred.
quantity	Quantity executed in the transaction.
timestamp	Timestamp associated with the trade.
outcome	Outcome represented by the traded market.
side	Transaction side, such as Buy.

Quote Fields

Field	Description
entry_time	Timestamp associated with the quote entry.
recv_time	Timestamp when the quote was received.
ask	Current ask price in the quote update.
bid	Current bid price in the quote update.
ask_volume	Quoted volume available at the ask price.
bid_volume	Quoted volume available at the bid price.

Available REST Endpoint

The Prediction Markets API provides a market-scoped endpoint for retrieving a recent batch of trades and quotes for one exchange and one market_id.

Retrieve Latest Market Activity

Returns recent trades and recent quotes for a selected prediction market. The endpoint is scoped to one exchange and one market. It does not require date-range or pagination parameters in the documented interface.

Response includes

recent trade records
recent quote records
execution prices and quantities
trade timestamps
trade outcomes and sides
bid and ask prices
quoted bid and ask volumes
quote entry and receipt timestamps

How Latest Market Activity Compares

Active Market IDs and Current Market Activity serve different purposes from Latest Market Activity. Use discovery endpoints to find markets, Current Activity for the freshest signal, and Latest Activity for a recent batch of events.

Latest Market Activity vs. Active Market IDs

The Active Market IDs endpoint is a lightweight discovery endpoint. It does not return trade prices, quantities, timestamps, or quote values.

Dataset	What it returns	Primary purpose
Active Market IDs	A list of market_id values derived from recent quotes and transactions.	Discover which markets have recent activity.
Latest Market Activity	Recent trade and quote records for one selected market_id.	Inspect what recently happened in that market.

The Latest Market Activity endpoint requires a specific exchange and market identifier and returns the underlying recent events for that market.

Latest Activity vs. Current Activity

The Prediction Markets API provides two endpoints for recent market state.

Endpoint	Response
/current	The single latest trade and the single latest quote for a market.
/latest	A recent batch of trades and quotes for a market.

Use Current Market Activity when an application only needs the freshest available trade and quote. Use Latest Market Activity when an application needs multiple recent records to examine short-term market behavior or display a recent activity feed.

The MCP documentation similarly describes activity_get_current as the freshest market activity signal and activity_get_latest as the option for retrieving more than one trade and quote.

How Latest Market Activity Fits Into the FinFeedAPI Ecosystem

Latest Market Activity follows exchange and market discovery. Applications first retrieve a supported exchange, discover a valid market identifier, and then request recent activity for that market.

Typical integration workflow

1Retrieve supported exchanges
2Discover market listings or active market IDs
3Select an exchange_id and market_id
4Retrieve recent trades and quotes
5Build feeds, monitoring systems, or analytics

Applications that only need the single freshest event can use Current Market Activity. Applications requiring longer time ranges can continue into the historical trade and quote endpoints.

Example API Request

Retrieve recent trades and quotes for a selected prediction market.

bash

curl -X GET \
  "https://api.prediction-markets.finfeedapi.com/v1/activity/POLYMARKET/WILL-RAIN-YES/latest" \
  -H "Authorization: YOUR_API_KEY"

json

{
  "trades": [
    {
      "id": "string",
      "market_id": "WILL-RAIN-YES",
      "price": 0.1,
      "quantity": 0.1,
      "timestamp": "2019-08-24T14:15:22Z",
      "outcome": "Yes",
      "side": "Buy"
    }
  ],
  "quotes": [
    {
      "entry_time": "2019-08-24T14:15:22Z",
      "recv_time": "2019-08-24T14:15:22Z",
      "ask": 0.1,
      "bid": 0.1,
      "ask_volume": 0.1,
      "bid_volume": 0.1
    }
  ]
}

The response separates executed trades from quote updates while keeping both datasets associated with the selected market.

REST, MCP, and JSON-RPC Access

Latest Market Activity is available through every FinFeedAPI interface. Regardless of the interface, applications use the same exchange and market identifiers.

MCP Server

The hosted Prediction Markets MCP server exposes the endpoint through the activity_get_latest tool, using the X-APIKey header. The tool requires exchange_id and market_id. It is intended for workflows that need more than the single latest trade and quote but do not require historical flat-file retrieval.

json

{
  "mcpServers": {
    "FinFeedAPI-Prediction-Markets": {
      "url": "https://api.prediction-markets.finfeedapi.com/mcp",
      "headers": {
        "X-APIKey": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Compatible with Cursor, Claude Desktop, and other MCP-enabled AI applications.

JSON-RPC

Developers using JSON-RPC can access market activity through the production proxy at https://api.prediction-markets.finfeedapi.com/jsonrpc.

JSON-RPC follows the same REST endpoint structure and exposes current, latest, and historical market activity methods through the proxy interface. Set method to v1/activity/{exchange_id}/{market_id}/latest and pass exchange_id and market_id through params. Successful JSON-RPC requests return the underlying REST payload in the result field.

Common Integration Patterns

Latest Market Activity is commonly used as a short-term event layer after market discovery and before historical retrieval.

Workflow	How Latest Market Activity is used
Recent Activity Feeds	Display recent trades and quote updates for a selected prediction market.
Price Monitoring	Track recent transaction prices together with changes in bid and ask quotes.
Short-Term Analytics	Examine recent price, quantity, spread, and quoted-volume changes.
Market Detail Pages	Add a recent activity section to individual prediction market pages.
Agent Workflows	Allow MCP-compatible agents to inspect recent market events without requesting flat-file history.
Historical Data Routing	Use recent activity first, then request historical trades or quotes when a longer analysis window is needed.
