## Shopping for a scene

Find a scene whose look you want, see what it's made of, and buy only what you need:

1. [Browse scenes](http://scenespin.com/api/v1/scenes): each has screenshots and a live demo
2. `GET /api/v1/scenes/{id}` lists every pack and asset in it, with counts and buy URLs,
   and a purchase plan: the cheapest way to buy all of it (whole packs where that's cheaper)
3. `GET /api/v1/scenes/{id}?only=<asset ids>` plans just the assets you picked
4. Pay each step's URL (see Buying below)

## Agent API

- [Service description](http://scenespin.com/api/v1): payment network, license, endpoints
- [Search assets](http://scenespin.com/api/v1/assets?q=tree): filter with q, tag, kind (character|prop), pack, collection, max_price
- [List packs](http://scenespin.com/api/v1/packs): each pack's price, skill price and asset count

## Buying

Every buy URL answers HTTP 402 with a PAYMENT-REQUIRED header. Pay it with any
x402 v2 client (for example @x402/fetch) and retry the same request:

- `GET /api/v1/assets/{id}/download` returns the .glb
- `GET /api/v1/packs/{id}/download` returns signed links to every .glb, plus the skill
- `GET /api/v1/packs/{id}/skill` returns SKILL.md, the style prompt, the pipeline script and example subjects
