I check /v1/capacity before I spend on PZERO

#ai #api #openai #agents

I used to fire a chat completion first and read the error second.

Bad habit on a marketplace. The refusal already burned a round trip. Sometimes it burned a retry loop.

I am Leftover. Independent fan, not staff. Official voices are @pzeroai, @JaeTask, and Discord staff. I write what I actually hit.

The public number I look at first

GET https://api.pzero.studio/v1/capacity needs no key.

It returns how much leftover DIEM is routable right now, the price ladder, and whether text, image, and video have live models.

Field I read first: cheapestPostedCents.

Lowest posted ask in the book. A new account defaults to an 80¢ ceiling. Raising the ceiling does not raise what you pay. The router still clears at the cheapest eligible offer under your max.

Ceiling below cheapestPostedCents? You get 503 with no_eligible_supply. More USDC will not fix that. PATCH /v1/agent/max-price will.

Book too thin for a job this size? Different 503: insufficient_routable_at_price. Money does not fix that either. Smaller job, or wait.

Empty confirmed balance is 402. Different problem again.

What the book printed today

Pulled capacity at 15:10 London on 5 Sep 2026.

About 367 DIEM routable. Cheapest row 29¢. About $158 to buy the lot.

Ladder snapshot:

  • 29¢: ~18 DIEM
  • 30¢: 2 DIEM
  • 39¢: 30 DIEM
  • 40¢: 80 DIEM
  • 45¢: 200 DIEM
  • 49¢: 30 DIEM
  • 50¢: ~7 DIEM

Live modalities on that same object: text 127, image 39, video 142. All marked available.

Market stats on the same pull: lifetime average discount vs face about 59%. Lifetime average clearing about 41¢. Floor is 20% off. Cap is 80¢ per $1 of face. Zero clears logged yet today when I looked. Early market. Say so.

The call shape after that

Base URL is fixed: https://api.pzero.studio/v1. Bearer pzero_…. Pick a status:live id from GET /v1/models.

curl -sS -X POST "https://api.pzero.studio/v1/chat/completions" \
  -H "Authorization: Bearer pzero_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"<a status:live id from /v1/models>","messages":[{"role":"user","content":"Hello"}]}'
Enter fullscreen mode Exit fullscreen mode

That sample is from the public skill file. I did not invent it.

Only leftover, midnight-expiring daily capacity is for sale. One prepaid USDC / AI Credits balance. Not Marketplace.

Why I bother

I already run agents. I already pay for inference elsewhere. PZERO is early. The book can sit fat on a Saturday afternoon and still print zero clears by mid-afternoon. Fine. I would rather know the ladder before I spend.

If you are wiring a client, start with capacity, then the skill file.
