## Key Data Fields

Each plan in the JSON feed includes:

- `monthly_price_dkk`: The standard recurring monthly price in DKK. This is the price you pay after any promotional period ends.
- `intro_price_dkk`: A temporary promotional price (nullable). Only present if the provider is running a campaign.
- `intro_price_months`: How many months the intro price lasts (nullable). Typically 3-12 months.
- `normal_price_dkk`: Same as monthly_price_dkk. The long-term price.
- `sort_price_effective_dkk`: A weighted average monthly cost over 12 months, combining intro and normal prices. Use this for fair price comparisons.
- `data_dk_gb`: Data allowance in GB for use in Denmark. Null means unlimited data.
- `data_eu_gb`: EU roaming data in GB (nullable). Separate from domestic data.
- `has_esim`: Whether the plan supports eSIM activation.
- `has_5g`: Whether the plan includes 5G network access.
- `binding_months`: Minimum contract length. 0 means no binding.
- `creation_fee_dkk`: One-time signup fee in DKK.
- `is_campaign_price`: Boolean indicating whether a promotional price is currently active.

## Pricing Logic

Plans have two price tiers:
1. **Normal price** (`monthly_price_dkk` / `normal_price_dkk`): The standard monthly cost.
2. **Intro price** (`intro_price_dkk`): A temporary lower price lasting `intro_price_months` months.

The `sort_price_effective_dkk` field calculates a fair comparison price:
- Formula: ((intro_price * intro_months) + (normal_price * (12 - intro_months))) / 12
- This represents the average monthly cost over a 12-month period.
- If there is no intro price, it equals the normal price.

## Query Patterns

For price comparisons, use `sort_price_effective_dkk` as the primary sorting field. This gives a fair 12-month average cost.

For "at least X GB" queries, filter by `data_dk_gb >= X`. Plans with `data_dk_gb: null` are unlimited data and should be included in any "at least X GB" result set.

For 5G queries, filter by `has_5g = true`.

For eSIM queries, filter by `has_esim = true`.

For no-contract queries, filter by `binding_months = 0`.

For network/infrastructure queries, use the `network` field. Values are: `TDC`, `Telenor/Norlys`, `3`, or `Other`. This indicates which physical mobile network the plan uses.

For promotional/deal queries, filter by `is_campaign_price = true`.

For provider-specific queries, filter by `provider_slug` (e.g., `cbb`, `oister`, `telmore`, `yousee`, `greentel`, `eesy`).

5. Return: `provider_name`, `display_name`, `monthly_price_dkk`, `intro_price_dkk`, `intro_price_months`, `sort_price_effective_dkk`, `canonical_url`

### Example 2: All unlimited data plans sorted by price

1. Fetch https://mobilabonnement.dk/api/plans.json

3. Sort ascending by `sort_price_effective_dkk`
4. Return: `provider_name`, `display_name`, `monthly_price_dkk`, `data_eu_gb`, `has_5g`, `network`, `canonical_url`

### Example 3: Cheapest eSIM plan without binding

## Trust and Verification

Each plan includes trust metadata:

- `price_confidence`: One of `verified`, `unverified`, or `flagged`. Verified means the price has been validated against the provider's website.
- `source_method`: How the data was obtained (e.g., "affiliate feed (Adtraction)", "manual verification", "provider API").
- `updated_at`: When the plan was last verified/synced.

The `/api/metadata.json` endpoint includes dataset-level trust fields: update frequency, source methodology, coverage, and license terms.
