API Reference

Health

GET /health

Account

GET  /api/v1/account/:publicKey              → account info
GET  /api/v1/account/:publicKey/balances     → { balances: { XLM: "...", ... } }
GET  /api/v1/account/:publicKey/transactions → paginated transaction list

Wallet

POST /api/v1/wallet/keypair  → generate a new keypair (public + secret)
POST /api/v1/wallet/send     → submit a payment transaction

Body for /send:

{
  "sourceSecretKey": "S...",
  "destinationPublicKey": "G...",
  "amount": "10.0000000",
  "asset": "XLM",
  "memo": "optional"
}

Concurrent /send calls for the same source account are serialized per-account (see docs/concurrency.md) — set LOCK_BACKEND=redis before running more than one instance of this API, or that serialization only holds within a single process.

Contract (Soroban — globe-wallet)

GET  /api/v1/contract/wallet/:publicKey/assets  → { assets: [{ code, issuer }] }
POST /api/v1/contract/wallet/spend              → { hash, ledger, successful }

GET .../assets is public (read-only, simulated, no fee). POST .../spend requires a Bearer token (same as /wallet/send) and body:

{
  "userSecretKey": "S...",
  "assetCode": "XLM",
  "amount": "1000000"
}

Requires GLOBE_WALLET_CONTRACT_ID — see .env.example and docs/soroban-integration.md for the design rationale and a real testnet run.

Price

GET /api/v1/price/:asset  → USD price (configure oracle in src/services/price.ts)
