# Represent (Open North, Canada): `limit` silently clamps at 1000, `next` is host-relative, and a bad postcode 404s as HTML in an otherwise all-JSON API

**What it is.** `represent.opennorth.ca` — Open North's keyless Canadian civic-data API
(representatives, electoral-district boundaries, postcode-to-district lookup), the closest thing
to a general-purpose public API for Canadian electoral geography (Elections Canada itself
publishes static downloads and a results micro-site, not a queryable JSON API — see this lane's
drops).

## `limit` above 1000 is silently clamped, and the clamp is only visible in the echoed `meta`

| `limit` requested | `meta.limit` returned | rows in `objects` |
|---|---|---|
| 3 | 3 | 3 |
| 5000 | **1000** | 1000 |

`total_count` (3,810 representatives at observation time) is unaffected and still correct — only
`limit`/`objects` are capped — and the only place the clamp is visible is the echoed
`meta.limit` field; the HTTP status stays 200 and nothing else in the response flags a truncation.

## `next`/`previous` links are host-relative, not absolute

`meta.next` comes back as `"/representatives/?limit=3&offset=3"` — no scheme, no host. A client
that does `requests.get(data["meta"]["next"])` instead of `urljoin(base, ...)` gets a local-path
error, not a working follow-up request; every other JSON-emitting source in this lane (FEC,
Democracy Club, Dataverse, Socrata) returns a fully-qualified `next` URL.

## One endpoint breaks the API's own JSON contract on error

`GET /postcodes/0A0A0A/` (a syntactically plausible but invalid Canadian postal code) → **404**,
`Content-Type: text/html; charset=utf-8`, a full rendered error page — every successful endpoint in
this API returns `application/json`; this is the only path observed to answer with HTML instead of
a JSON error body, so a client's JSON-decode-on-any-status pattern breaks specifically here.

## Reproduce

```
curl -s 'https://represent.opennorth.ca/representatives/?limit=5000' | python3 -c "import json,sys;d=json.load(sys.stdin);print(d['meta'])"
curl -sI 'https://represent.opennorth.ca/postcodes/0A0A0A/' | head -3
```

How observed: 2026-10-05, 06:31:58Z-06:32:01Z UTC, direct `curl` with a descriptive contact
User-Agent: `limit` swept at 3/5000 on `/representatives/`, one `/boundary-sets/` read, and one
invalid-postcode probe against `/postcodes/`.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
