For organisers

You handed out $1,000 in inference.
The debrief shouldn't be guesswork.

Issue each hacker a metered key instead of pasting one in Discord, and get one verifiable spend report for the debrief — who used what, what it cost, checkable by your sponsors. No participant accounts, no markup, no spreadsheets.

Sample report, zero signup — the shape of what your sponsors would see. Or check the live proof before you sign in.

Have credits, codes, or seats? Route what you can, register the rest — the report shows both, labeled.

  1. Budget
  2. Keys
  3. Spend
  4. Receipt
  5. Record

Keys in one paste

Paste a participant list, mint every budgeted key in one atomic batch, hand them out with one CSV.

0% fees, pass-through pricing

Every call is metered at provider pricing into an append-only ledger. No markup, no spread — reconcilable at any time.

A receipt anyone can check

Balances are committed to a Merkle root anchored on public networks. Drop the verification link in your recap.

How it works

From budget to verifiable receipt

  1. 1

    Create a program

    Pool, per-hacker allocation, allowed models, window. About 5 minutes, once.

    ~5 min

  2. 2

    Paste your cohort

    One list of handles mints every budgeted key in a single batch — no more Discord key pastes.

    ~2 min

  3. 3

    Hackers build

    They point any OpenAI-compatible SDK at the gateway. No accounts, no onboarding calls.

    0 min of yours

  4. 4

    Drop the link in your debrief

    Spend, task split, and a receipt your sponsors can verify themselves.

    ~1 min

Anyone can check the math without trusting you — the public verification page verifies inclusion against the anchored root.

Test it before you trust it

  1. 1 · Open the sample

    The report your sponsors would see. No signup, clearly labeled sample data. View it

  2. 2 · Mint two test keys

    Sign in, create a program, provision two keys on a $5 pool. About ten minutes.

  3. 3 · Burn a call, watch the ledger

    Run one completion through the gateway and see it metered, attributed, and receipted.

Fund the cohort. Keep the evidence.

Set up a sponsored program in minutes, then hand every participant a key and a receipt they can verify themselves.
