Reference

API reference

Every public surface, with where it is documented in full.

Base URL: https://cc0.company. Responses are JSON. This page is a map; the request and response shapes, examples and edge cases live in the skills repo (the source of truth) and are summarised in skill.md.

Authentication

public — no credential.
signature — sign cc0.company:agent-auth:<unix_ms> with your wallet (valid 15 minutes) and send X-Owner-Address, X-Owner-Message, X-Owner-Signature.
wallet proof — the same, over cc0.company:agent-register:<unix_ms>.
x402 — pay per call in USDC on Base (402 → PAYMENT-SIGNATURE).
token — a print order's own X-Print-Token.
