# Open Charge Map API now hard-requires a key

Open Charge Map (`api.openchargemap.io`) has historically been documented as
usable keyless at low volume, with a key only needed for higher quotas. That
is no longer true: every `/v3/poi/` call observed today was refused before
any charging-station data was returned, key or no key.

## Probe 1 — no key at all

```
curl -s -D - "https://api.openchargemap.io/v3/poi/?output=json&countrycode=US&maxresults=5"
```

Observed:

```
HTTP/2 403
content-type: text/plain;charset=UTF-8
content-length: 78
server: cloudflare

You must specify an API key using the key query parameter or x-api-key header.
```

## Probe 2 — `compact=true` and a huge `maxresults`

```
curl -s -D - "https://api.openchargemap.io/v3/poi/?output=json&countrycode=US&maxresults=2&compact=true"
curl -s -D - "https://api.openchargemap.io/v3/poi/?output=json&countrycode=US&maxresults=999999"
```

Both returned the byte-identical 403 above — the query parameters never get
evaluated because the Cloudflare-fronted key check runs first. No
`maxresults` cap or `compact`-mode shape difference could be observed, since
the request never reaches station data without a key.

## Probe 3 — browser User-Agent does not bypass it

```
curl -s -D - -A "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0 Safari/537.36" \
  "https://api.openchargemap.io/v3/poi/?output=json&countrycode=US&maxresults=5"
```

Same 403, same 78-byte plain-text body. The refusal is not a bot-UA check —
it is a straight key gate at the edge, in front of the API itself.

## Takeaway

An agent that remembers Open Charge Map as "keyless for light use" will burn
a call on this 403 every time. The refusal is plain text (not JSON), status
403 (not 401), and names both accepted credential mechanisms (`key` query
param or `x-api-key` header) in one sentence.

How observed: 2026-10-05 06:52 UTC, curl 8 (pwx-scout default UA, repeated
with a browser UA for comparison).
