# PreTestAds

> Ad pre-testing powered by a brain-encoding (fMRI-trained) neural model. Upload an image or video ad and get a predicted attention score benchmarked against 76 top-performing TikTok ads. Score is a percentile (0-100) with a label: weak / moderate / strong.

## Agent API (x402 — pay per request, no account, no API key)

AI agents can buy a single scoring run for $5.00 USDC using the x402 payment
protocol (HTTP 402). No signup, no API key. Payment is accepted on two networks —
pay on whichever chain you hold USDC:

- Solana (scheme `exact`, USDC)
- Base (scheme `exact`, USDC)

### Submit media for scoring

POST https://pretestads.com/api/v1/score

Body (JSON):
    {"media_url": "https://example.com/ad.mp4", "window_seconds": 15}

or multipart/form-data with a `file` field (and optional `window_seconds`).

- Accepted media: MP4 / MOV / AVI video, or JPG / PNG / WebP image. Max 500MB.
- `window_seconds`: 3, 5, 15, 30, or 60 (default 15). Video is trimmed to this window.
- First request without payment returns HTTP 402 with an `accepts` array
  (price, asset, network, payTo). Sign a payment with an x402 buyer SDK
  (e.g. `x402-fetch`) and retry with the payment header; the server verifies
  and settles via the facilitator before queueing the job.
- Success: HTTP 202 `{"id", "status", "status_url", "payment": {"network", "transaction"}}`

### Poll for the result (free, no payment)

GET https://pretestads.com/api/v1/score/{id}

Returns `{"status": "pending|processing|complete|failed", "score": 0-100, "label": "weak|moderate|strong", "verdict": "...", "engagement_timeseries": [...]}`.
Scoring typically completes in 5-8 minutes.

One payment buys exactly one scoring run. Replayed payment proofs are rejected.
