Live election results API

Carmena’s Overton collects live election results from more than 3,300 feeds and normalises them to one schema. Every vote change from any source is pushed within about a second of being collected, over a WebSocket and as JSON. On election night each feed is checked every 15 minutes, with the checks staggered across all 3,300 so some feed is checked every minute, and a change reaches subscribers within about a second of the check that finds it. In 2026 the feed covered about 2,200 races, each with a live results page.

Sources

• AP, and the media outlets that carry AP’s count: NYT, NBC, Fox, NPR and Bloomberg.
• Decision Desk HQ.
• Official state and county election sites.

When sources disagree, the newest report from any source wins. Each county or district total names the source of its current count, so one race can mix sources: in the Pennsylvania governor file on 5 November 2026, the statewide total was NPR’s and the county figures were NBC’s.

AP race calls

The feed carries AP race calls with the time of each call. AP called the Pennsylvania governor race for Josh Shapiro at 01:01 UTC on 4 November 2026, which was 8:01 p.m. Eastern on election night.

Public JSON endpoints

Two read-only endpoints are open to anyone, with CORS open (Access-Control-Allow-Origin: *):

• https://carmenaresearch.com/live/races.json lists every race, with its state, office, last update, share reported and the leading candidates’ vote shares.
• https://carmenaresearch.com/live/race/<slug>.json returns one race in full: the statewide or district total, results by county, and race calls. The slug is the one in the race page’s address, for example pennsylvania-governor.

This is a record from https://carmenaresearch.com/live/race/pennsylvania-governor.json, fetched on 5 November 2026 and trimmed to the statewide total and one county. The full file has all 67 counties and a Kalshi market block.

The fields:

• office is G for governor, S for Senate, H for House and O for other contests, including ballot measures.
• updatedAt is the time of the race’s latest change.
• calls lists race calls: winner, party, who called it (by) and when (at).
• areas holds the results, keyed top for the statewide or district total and by FIPS code for counties. Each area has the percentage reported as its source gives it, the source and time (at) of its current count, and c, a list of candidate, party and votes.

Times are UTC. Candidate names are written as each source writes them, which is why the statewide total above says “Shapiro” and the county says “Josh Shapiro”.

Race pages

Every race in the feed has a page with the latest count and a county map, listed at 2026 results, race by race. Examples: Pennsylvania governor, North Carolina Senate and Texas Senate.
