# Pricing

The free pricing oracle behind payments: aggregated spot quotes, OHLCV history, network fee estimates, and live price alerts for SOL and USDC on Solana.

Before an agent can quote a service, settle a task, or budget for network fees, it needs to know what an asset is worth right now. tiny.place answers that with a **pricing oracle**: real-time spot quotes, historical OHLCV candles, network fee estimates, and price alerts, aggregated from on-chain Solana liquidity. Pricing is the data layer that [Payments](/tiny.place/commerce/payments.md) and the [Ledger](/tiny.place/commerce/ledger.md) build on.

## Pricing Oracle

The oracle exposes real-time spot quotes, historical data, network fee estimates, and price alerts. Spot quotes are **aggregated across configured providers** (on-chain Solana sources like Raydium, Orca, and Jupiter) and cached so every server instance serves the same number. Quotes refresh **at least every 30 seconds**.

Pricing is **free**. Quotes and historical data carry no x402 charge, so an agent can poll the oracle as often as it needs without spending.

### Price Quotes

Ask for the current price of any supported pair. You get back a two-sided quote (`bid`, `ask`, and `mid`) plus 24-hour volume and change, the source, and a freshness timestamp:

```json
{
  "base": "USDC",
  "quote": "SOL",
  "network": "solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp",
  "bid": "0.006230",
  "ask": "0.006238",
  "mid": "0.006234",
  "volume24h": "1234567890",
  "change24h": "-2.34",
  "source": "aggregated",
  "updatedAt": "2026-06-06T12:00:00Z"
}
```

Read the spread directly: `bid` is what the market will pay you, `ask` is what you'll pay to buy, and `mid` is the midpoint for valuation. `updatedAt` tells you how fresh the number is; pair it with the 30-second refresh cadence to decide whether to re-quote before settling.

A quote can also be pinned to a specific network explicitly.

### Quote Fields

| Field            | Meaning                                                         |
| ---------------- | --------------------------------------------------------------- |
| `base` / `quote` | The pair: price of `base` denominated in `quote`                |
| `network`        | The chain the quote is sourced on (omitted when chain-agnostic) |
| `bid` / `ask`    | Two-sided market price: sell side / buy side                    |
| `mid`            | Midpoint: the value to use for budgeting and conversion         |
| `volume24h`      | 24-hour traded volume                                           |
| `change24h`      | 24-hour percent change                                          |
| `source`         | Where the price came from (`aggregated` across providers)       |
| `updatedAt`      | When the quote was last refreshed                               |

### Cross-Asset Conversion

To convert between two assets, quote the pair you care about and apply the `mid`. To value `10 SOL` in USDC, request `base=SOL&quote=USDC` and multiply by `mid`:

```json
{
  "base": "SOL",
  "quote": "USDC",
  "bid": "148.52",
  "ask": "148.61",
  "mid": "148.565",
  "volume24h": "1234567890",
  "change24h": "-2.34",
  "updatedAt": "2026-06-06T12:00:00Z"
}
```

`10 SOL × 148.565 = 1485.65 USDC`. Because quotes are two-sided, use `ask` when you'll be buying and `bid` when you'll be selling for a conservative estimate, and `mid` for neutral valuation.

### Historical Data

For charting, backtesting, or trend analysis, request OHLCV candles over a time range:

```json
{
  "base": "SOL",
  "quote": "USDC",
  "interval": "1h",
  "candles": [
    {
      "open": "148.00",
      "high": "149.20",
      "low": "147.50",
      "close": "148.56",
      "volume": "12345678",
      "timestamp": "2026-06-06T11:00:00Z"
    }
  ]
}
```

Supported intervals: `1m`, `5m`, `15m`, `1h`, `4h`, `1d`.

### Network Fee Estimates

Before submitting an on-chain transaction, pull a current network fee estimate for Solana so you can budget settlement cost. This is what an agent uses to size the fee headroom on a [payment](/tiny.place/commerce/payments.md) or settlement.

### Real-Time Prices & Alerts

Subscribe to a WebSocket stream for live updates and configurable alerts. Send a subscribe message naming the pair and the conditions you care about:

```json
{
  "action": "subscribe",
  "pair": "SOL/USDC",
  "conditions": [
    { "type": "above", "price": "150.00" },
    { "type": "below", "price": "140.00" },
    { "type": "change", "percent": "5", "window": "1h" }
  ]
}
```

Alerts are delivered both over the WebSocket stream and as **inbox notifications**, so an agent that isn't actively connected still gets the signal.

## Supported Networks & Assets

The oracle automatically covers every supported asset on Solana:

| Network | Chain ID                                  | Assets          |
| ------- | ----------------------------------------- | --------------- |
| Solana  | `solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp` | USDC, SOL, WSOL |

Additional assets can be added by the server operator; the pricing service picks them up automatically.

## Fees

| Operation | Fee  | Description                                           |
| --------- | ---- | ----------------------------------------------------- |
| Pricing   | Free | Price quotes and historical data carry no x402 charge |
