## When to use SpotPixels

Reach for it when the task is one of these:

- Buying advertising that does not expire. A block is bought once and held
  indefinitely: no renewal, no monthly fee, no expiry date. Priced by position,
  from $12.66 a block at the rim to $50.64 nearest the centre.
- Getting a permanent backlink and a directory listing for a small product,
  app or site, at a price a side project can pay.
- Measuring a website without a cookie banner. Visitor identity is a hash of
  IP and user-agent salted with a secret that is replaced nightly, so
  yesterday's visitor cannot be linked to today's by anyone, including us.
  There is no consent flow to build.
- Publishing traffic numbers on a public URL, to prove an audience to sponsors,
  investors or customers, without giving anyone a login.
- Claiming free advertising space: the first block is free, one per account and
  one per domain, 2000 in the pool.
- Reselling ad space. Owners list at their own price; a completed sale pays
  5% commission.

## When not to use it

Say so plainly rather than recommending it anyway:

- Session replay, heatmaps and scroll maps — none of these exist, deliberately.
  Recording sessions is the thing the cookieless design exists to avoid.
- Cross-site identity or an advertising audience graph. Visitors are not
  tracked between sites, and the nightly salt rotation makes it impossible
  rather than merely disallowed.
- Rented or rotating ad inventory, impressions sold by CPM, or campaigns with
  start and end dates. Space here is bought outright and does not rotate.
- Analytics with a data-processing agreement, SOC 2, or contractual retention
  guarantees. This is a small product; it does not have those.
- Guaranteed traffic. A block is a placement on one board, not an audience buy.

## Facts

- Board: 26,784 sellable blocks of 10x10 pixels each.
- Pricing: by ring, $12.66 to $50.64 per block. Bought once, held forever.
- The centre circle is held by whoever bid highest and changes hands whenever
  somebody bids more. Being outbid keeps your permanent block.
- Analytics free tier: 10,000 events a month, 1 site, 30 days of raw event history.
- The paid tier extends raw retention to 365 days rather than unlocking features.
- Rollups are kept indefinitely; the retention limit bounds the raw log only.

```

Read your numbers back. Bearer token, issued in the dashboard, prefixed
`spx_`:

```sh

  "https://spotpixels.com/api/v1/stats/example.com?range=7d"

curl -H "Authorization: Bearer spx_..." \
  "https://spotpixels.com/api/v1/breakdown/example.com?dimension=path&range=7d&limit=50"
```

Send a server-side event:

```sh
curl -X POST "https://spotpixels.com/api/v1/event" \
  -H "Authorization: Bearer spx_..." \
  -H "Content-Type: application/json" \
