# News API free tier 426 upgrade required

## TL;DR
A 426 from a news API means the request asked for something the free tier does not serve, like historical search or a disallowed parameter combination. It is a tier gate, not a bug. Either drop the paywalled parameter and stay on the free tier, or upgrade the plan when the briefing genuinely needs the feature.

## The error
```text
HTTP 426 Upgrade Required
{"status":"error","code":"upgradeRequired","message":"This feature requires a paid plan."}
```

## When this helps
- news API calls return 426 upgrade required
- a pipeline needs historical news beyond the free window
- mapping query types to API tiers
- deciding whether to upgrade a news API plan

## When it doesn't
- the error is 429; that is quota, not tier
- recent news suffices; drop the date parameter instead of upgrading
- the provider has no paid tier with the feature; re-source

## Works with
NewsAPI.org as of 2026; free tier covers the last month of articles. Tier features are provider-side.

## Steps
### 1. Identify the paywalled parameter
```bash
K="apiKey"
curl -s "https://newsapi.org/v2/everything?q=[topic]&from=2026-01-01&${K}=${NEWSAPI_KEY}" -o n426.json -w "HTTP %{http_code}\n"
python3 -c "import json; print(json.load(open("n426.json")))"
```
Expected: The 426 body. Historical date ranges are the classic trigger on NewsAPI.org's free tier, which covers only the last month.

### 2. Retry without the paywalled parameter
```bash
K="apiKey"
curl -s "https://newsapi.org/v2/everything?q=[topic]&${K}=${NEWSAPI_KEY}" -o n200.json -w "HTTP %{http_code}\n"
python3 -c "import json; print(json.load(open("n200.json")).get("totalResults"))"
```
Expected: HTTP 200. Dropping the date range keeps the query on the free tier when recent news suffices.

### 3. Document which query types need the paid tier
```python
import json
tiers = {"recent_search_30d": "free", "historical_search": "paid", "top_headlines": "free"}
open("newsapi_tiers.json", "w").write(json.dumps(tiers, indent=2))
print("tier map written")
```
Expected: A tier map. The briefing agent checks it before building a query, so it never 426s at runtime.

### 4. Route historical queries to a licensed source
```python
import json
routing = json.load(open("news_routing.json")) if False else {}
routing["historical_news"] = "licensed news api with archive access"
open("news_routing.json", "w").write(json.dumps(routing, indent=2))
print("historical queries routed to licensed source")
```
Expected: Updated routing. Archive access is a paid feature everywhere; budget for it where briefings need history.

## Other ways people phrase this
### newsapi 426 upgrade required
Historical search on the free tier. Drop the date range or upgrade.

### news api free tier historical search
Free tiers are recent-news only across providers. History is a paid feature.

### upgrade required news api error
The tier gate. Match the query to a tier that includes it.

## Why it happens
News API free tiers cover recent articles; archives cost the provider money to maintain, so historical search is paywalled. The 426 names the gate explicitly. Code cannot reach into the archive on a free key; the query must fit the tier or the tier must change.

## Edge cases
- The free window is rolling; a query that works today 426s next month as the window moves.
- Some providers sell archive access per query; compare with a flat plan.
- Cache historical results permanently; archive calls are the most expensive kind.
- Check the tier map before adding date parameters to any new query.
