Jat ships a small set of HTTP endpoints for status, the indexer, and the relayer. None of them take a spend key, and the sensitive work happens in your browser.

Status

GET /api/health

Service status, network, and the live program identifiers. Useful for uptime checks and verification.

{
  "status": "ok",
  "name": "Jat",
  "network": "solana-devnet",
  "stage": "pre-launch",
  "program": "seuH78RmBPVzoKToLQVEZrDvuL5jDNBSbptozWK9PEm",
  "programs": { "pool": "...", "announcer": "..." },
  "token": null,
  "version": "0.1.0"
}

GET /api/token

The current token contract status. It returns pre-launch with a null address until a token exists, and never reports a fabricated address.

{ "status": "pre-launch", "ca": null, "symbol": null }

Indexer

The indexer serves public on-chain data only. It never receives keys; your browser scans the raw results locally.

GET /api/indexer/announcements returns the raw stealth announcements to scan against your scan key.
GET /api/indexer/pool/leaves returns the public list of pool deposit leaves, used to rebuild the Merkle path in the browser.

Relayer

The relayer pays the network fee for a transaction you signed. See the fee relayer for the trust model.

GET /api/relayer/health reports relayer availability.
POST /api/relayer/relay submits a signed transaction for the relayer to pay the fee on. It rejects anything that would let it be drained.

Note

The hosted endpoints live on the Jat domain so the site flows work with no setup. To run your own indexer and relayer, see run the services.

Admin

A single authenticated endpoint manages the token contract address when one exists. It requires a bearer secret, compares it in constant time, and is disallowed in robots.txt for every crawler. It is not part of the public API and is documented here only for completeness.
