Core Concepts

x402

HTTP 402 Payment Required challenges carry amount, payTo, asset, and network. Clients pay on-chain, then POST proof to unlock.

Free evaluation

Every curated skill exposes free:

• /skills/{id}/outline.json

• /skills/{id}/sample.md

• /skills/{id}/assets/* (preview, schema, checklist)

Sealed packs

Full runtimes live under lock until verified payment. Teasers may exist under /sealed/; full files arrive only after unlock.

Proof ledger

Confirmed unlocks only: /api/proof. Quiet is honesty.
