Try it

The API is open. Fair-use rate limits apply per IP, and localhost origins always work in the browser:
Shipping to production? Fill in the whitelist form and we whitelist your origin: guaranteed access and a heads-up before breaking changes.

​
Endpoints

Base URL: https://api.ctoken.inco.org/api (Base). Base Sepolia lives at https://api.ctoken.testnet.inco.org/api. Amounts are decimal strings. Encrypted values only ever appear as bytes32 handles.

​
Pagination

List endpoints take page and limit (max 100) and return { items, total, page, pages, limit }. Totals are counters maintained at indexing time, so they stay fast at any history size.

​
Under load

Hot responses are cached briefly and served last-known-good during database hiccups. If the API is saturated it answers 503 with a Retry-After header instead of hanging. Honor it, the SDK already does.

​
Privacy

The indexer stores what the chain emits and nothing more. Confidential amounts never touch it in plaintext. Public amounts exist only where the chain makes them public: wrap and unwrap legs, and explicit disclosures.
