Daily caps: why an offer leaves the feed mid-day

• The Offer API list leaves it out. The list only holds offers that can take a new user now. No parameter brings a full offer back sooner.
• The Offers page keeps it, marked. In the portal the row stays, with Capped for today and when it reopens, such as Reopens at midnight EDT. Its button reads View offer instead of Get offer, and the offer’s page holds the tracking link back and points to Run it now: open copies of this offer. If we don’t know when the cap resets, the offer is hidden instead.
• Another copy may take its row. If the same app is listed more than once, the best open copy shows in its place. See How we pick which copy of an offer you see.
• Old links stop before the advertiser. When we know an offer is full, a tap from a card you saved earlier doesn’t reach a store page that can’t credit it. The player lands on one of our pages, such as “This offer has ended” or “Download a game”, that tells them to go back and pick another offer.
• Players who already started carry on. A cap counts new users, so the first step uses it up and later steps don’t. Steps from players who started before the cap filled still post back.

Harbor Blocks, an iPhone game, takes a set number of new players a day, and its cap resets at midnight Eastern time.

Example. Times and numbers are made up.

Rows carry these fields when we report caps on the API. Offers without a known limit return them as null.

On some offers cap is only an estimate across everyone, and taps still go through at 0. Use available, below, to decide whether to show a card.

If part of an offer’s cap is set aside for one publisher, the cap every other publisher sees already leaves that part out. When what’s left reaches 0, the offer is unavailable and its link refuses new taps until the set-aside part is used or the US Eastern day ends.

If your account has its own daily limit on an offer, set by us or by the network you work with, cap counts down from that limit instead.

If you keep offer cards between calls, ask which are still open:

curl -G "https://affiliateos.xyz/publisher/offers/availability" \
  --data-urlencode "ids=aff_7c2e91b04d3a,aff_51d0c3e8a9f2" \
  -H "x-api-key: $AFFILIATEOS_KEY"

{
  "status": "success",
  "data": {
    "offers": [
      {
        "id": "aff_7c2e91b04d3a",
        "available": false,
        "cap": 0,
        "capResetsAt": "2026-10-31T04:00:00.000Z"
      },
      {
        "id": "aff_51d0c3e8a9f2",
        "available": true,
        "cap": null,
        "capResetsAt": null
      }
    ],
    "checkedAt": "2026-10-30T15:25:00.000Z"
  }
}

Example: Pebble Rewards’ 11:25 AM check, Harbor Blocks first. IDs and times are made up.

• Send up to 100 IDs a call, comma-separated.
• Hide a card when available is false. Read available, not cap: an offer can report cap: 0 for display and still be open.
• An ID that’s unknown to your account reads available: false.
• Don’t bring a card back because capResetsAt has passed. Bring it back when a new check says available: true.

Open Email alerts in the portal. Offer stopped emails you when an offer you earn on stops being available and stays gone for 15 minutes, 1 hour or 4 hours, right away or in the daily summary; tick Also tell me when it comes back to hear when it returns. Payout or cap changes, with Include daily cap changes ticked, emails you when an offer’s daily cap changes.

The Network API leaves full offers out the same way, and GET /network-api/offers/availability?ids= answers the same question with your network’s ak_ key. On offers that support it, you can also set a Daily cap for each of your publishers when you assign them the offer in your network dashboard.
