# Solana Transaction API
> Decode any Solana transaction by its signature, live from public Solana RPC — no key. Where a signatures list just tells you a transaction happened, this tells you what it did: the fee and fee payer, success or failure with the on-chain error, the slot and block time, compute units consumed, the parsed instructions and full program log, and — most usefully — the actual value that moved, decoded into SOL balance changes and SPL-token balance changes per account. A dedicated transfers endpoint extracts just the money movements, and a status endpoint gives a fast confirmation check (processed / confirmed / finalized) for payment flows. Call any endpoint without a signature and it returns a fresh live example transaction. The transaction-decoding layer every Solana wallet, explorer, payment processor and trading bot needs. Live from the chain; short cache only.

## Authentication
All requests require your oanor API key in the `x-oanor-key` header. Get one at https://www.oanor.com/developer/keys.

```bash
curl -H "x-oanor-key: oanor_live_…" "https://api.oanor.com/solanatx-api/..."

### Transaction

#### `GET /v1/status` — Fast confirmation status of a signature

**Parameters:**
- `signature` (query, optional, string) — Transaction signature (base58); omit for a fresh live example

**Example:**
```bash
curl -H "x-oanor-key: $KEY" \
  "https://api.oanor.com/solanatx-api/v1/status"
```

**Response:**
```json

#### `GET /v1/transfers` — Just the value moved: SOL + SPL-token balance changes

**Parameters:**
