DCFC Tracker API

1. Subscribe to Pro.
2. On your account page, create a key under API access and copy it. It’s shown once.
3. Send it with each request:

curl -H "Authorization: Bearer $DCFC_API_KEY" \
  "https://dcfctracker.com/api/v1/stations?states=TX&networks=Tesla,IONNA&limit=100"

Send your key in the Authorization header as a Bearer token. Keys start with dcfc_. Keys in query strings aren’t accepted.

Authorization: Bearer dcfc_…

You can have up to 3 active keys and revoke any of them from your account page. Keep keys on a server or in a script’s environment. Don’t put them in a web page, a mobile app or a public repository. Keys stop working if your Pro subscription ends and start again when you resubscribe.

The API doesn’t send CORS headers: call it from a server or a script, not a browser.

Pro includes 3,000 requests per day per account, across all your keys. The count resets at 00:00 UTC. Pages hold up to 1,000 stations, so the full catalog takes about 15 requests. Each network refreshes on its own schedule, from hourly to daily, so syncing once or a few times a day is plenty.

Every request that passes authentication counts, whatever its result (200, 400, 404 for an unknown station, 500), and carries your quota. 401s, 403s, 429s, /usage and unknown endpoints don’t count.

API requests from all users run at most two at a time on each server. Others wait in a short line for up to 10 seconds. Past four waiting from your key, or 20 in all, a request gets 429 rate_limited with Retry-After: 1, which doesn’t count. Send one or two requests at a time and you’ll rarely wait.

Every counted response carries your quota:

Past the limit, requests get 429 with a Retry-After header. Need more? Email [email protected].

Every endpoint reads its parameters strictly, so a typo can’t silently widen or empty a result:

• An unknown parameter, or one given twice, is a 400 invalid_parameter that names it, e.g. Unknown parameter: network.
• An empty value (states=) counts as absent.
• Booleans are 1, 0, true or false. Dates are real calendar dates written YYYY-MM-DD, and every date is a UTC day.
• page runs from 1 to 1,000,000; limit is 1 to 1,000.
• Network ids, state codes and connector types match without regard to case. Network ids come from /networks.
• Parameters that would contradict each other are 400s: networks with excludeNetworks, a …Within preset with its date range, a bounding box missing an edge, a range that ends before it starts.
• Endpoints without parameters (/networks, /usage, /price-index) reject any.

Sites matching the filters, newest opening first by default. All parameters are optional.

One station with its prices, availability and hardware history. station is the row /stations returns for this id: for a site with several ChargePoint chargers, the site’s combined values. A charger merged into a site still answers to its own id, with its own values; add expandSites=1 (the only parameter) to get a site’s primary charger’s own values too. site is set when the station is one of several chargers merged into a site, and lists them. timeZone is the site’s local IANA zone.

pricing is the site’s price schedule: one track per rate (public, member for the Tesla-vehicle or Rivian member rate, or single), each with time-of-use windows in the site’s local time (24:00 is the end of the day) and a flatRate to use when there are no windows. Windows are in time order and never cross midnight: an overnight rate shows as two windows, one ending at 24:00 and one starting at 00:00. Schedules repeat every day; a few Tesla sites price by the minute, which unit says. note names the price source and when it was last updated. pricing is null when the site has no price or is free.

hardwareHistory lists the site’s stall, connector and power changes, oldest first, in the same shape as the hardware changes below. It starts when tracking began (the changes endpoint’s historyStart) and can be null if change data is briefly unavailable.

All histories are oldest first. priceHistory holds up to the last 100 price snapshots, each with connectorType (NACS, CCS or CHAdeMO where a network prices per connector; null for all connectors), rate and sourceType. statusHistory holds up to the last 100 availability changes. For a merged site, pricing, priceHistory and statusHistory describe the charger whose id you asked for (site.members lists every charger at the site); hardwareHistory covers the whole site.

Changes across every tracked site: the same data as the Recent changes page, with every change listed on its own. Newest first by default; history goes back to historyStart. Changes are refreshed hourly (generatedAt).

Kinds:

Each change has kind, kinds (every kind it qualifies for: a conversion that also added stalls is both), category, date, site, and one block for its category:

What date means:

A change’s id never changes once published, so you can store changes by id. A change can still be revised or withdrawn after it appears:

• Hardware and price changes settle within 7 days. Until then their kind, date and details can change, and a price change reversed within two days is withdrawn. A price change that turns out to be a repeating cycle becomes price_varies under the same id, and its date follows the latest swing.
• An outage (offline) keeps updating until it ends (ongoing, endedAt, hours), and is withdrawn if its recovery can’t be established.
• A removal (delisted) is withdrawn as soon as its site is listed again, however much later. Most are.
• All of a site’s changes are left out while a site is removed from the listing, and come back with it.

To keep a copy in sync, fetch from your last poll minus 7 days every hour or so and upsert by id. Once a day, re-fetch everything from historyStart and replace your copy: that picks up ended outages and changes withdrawn at any age. A fetch that spans several pages is one consistent snapshot only if every page has the same generatedAt; if it changes partway, start that fetch again.

The daily US price index behind the charging prices page: a national average and one per state (the 50 states and DC) for every UTC day since historyStart. /price-index returns the newest day with its changes over 1, 7, 30 and 90 days, states in code order (a state with no priced stations that day is left out). /price-index/history returns one value per day, oldest first; a day with no data is skipped. Dates here, historyStart included, are UTC days written YYYY-MM-DD.

How it’s calculated: for each station, the latest positive per-kWh price on record at the end of the UTC day: the network’s own published price where we have one, otherwise the DOE (AFDC) listing’s. Where a station has several per-kWh rates (by time of day, power level or connector), it’s the highest. At Tesla Superchargers it’s the price for non-Tesla vehicles wherever Tesla has published one, otherwise the Tesla-vehicle price. Those prices are averaged across stations, not weighted by stalls. The index covers open DC fast stations with CCS or NACS; stations with only free or per-minute prices are left out. The national figure also counts priced stations outside the 50 states and DC, so the states’ counts don’t add up to it.

The index updates every morning at 07:00 UTC. The newest day (the snapshot’s date, the history’s provisionalDate) is provisional: it’s recalculated the next morning, once the whole day’s prices are in, and is final after that unless we correct an error.

Your quota for today. This request doesn’t count against it.

Fields and parameters may be added to v1, and new values may appear in lists such as change kinds, networks, connector types, access kinds and price source types, so ignore what you don’t recognize. Anything that would break existing code goes in a new version, announced in advance: v1 stays available for at least 12 months after a v2 is announced.

Prices. pricePerKwh is the highest public per-kWh price: where a network charges different rates by time of day, power level or connector, it’s the highest. 0 means free; null means no per-kWh price (unknown, or priced per minute or per session). pricing is null when the site has no price or is free. Time-of-use windows exist only where a network publishes a schedule (Tesla, Rivian, ChargePoint and Walmart today); elsewhere each track has a flatRate.

For a site with several ChargePoint chargers, pricePerKwh is the highest of their prices, while priceSource, priceSourceType, priceRate, priceNote and priceUpdatedAt describe the site’s primary charger, so they can differ from the charger that sets the price, or be null.

Status. status is the network’s own live signal where we read one, while it’s under 3 days old; otherwise the DOE (AFDC) listing’s.

First seen. A firstSeenAt before 2026-03-01 means the site predates tracking: the first import stamped about 12,400 long-open sites on February 14–17, 2026.

Station ids are stable. A station missing from the DOE listing for 48 hours stops answering (404) and keeps its id if it comes back. When a network re-keys its sites, old ids don’t redirect.

Display text. These fields may be reworded, so don’t parse them: priceSource, priceNote, networkName, pricing.note, pricing.tracks[].label, priceHistory[].source, reportedBy and the changes price.source. Use priceSourceType and priceRate in code.
