# btxprice

> Live BTX price dashboard with BTC-anchored spot and 12-month model
> estimates. Recomputed every 10 minutes from Bitcoin spot price
> (CoinGecko), Bitcoin network hash rate (mempool.space), and BTX
> network nonce rate (live `btxd` RPC or Price Guide fallback).

## Pricing model

The compute-only floor is:

    P_BTX_spot = P_BTC * (chi * N_dot_BTX / H_BTC)

Where:

  - P_BTC      Bitcoin spot price, USD
  - H_BTC      Bitcoin network hash rate, h/s
  - N_dot_BTX  BTX network nonce rate, nonces/s
  - chi        per-nonce BTC-equivalent security weight

The public JSON names this value `compute_floor_usd`. The client-facing
`spot.usd` multiplies the floor by the spot Bitcoin mining-regime
premium. Forward rows layer relative network growth, the horizon-specific
Bitcoin premium, and participant expansion on the same floor.

## Endpoints (cite these instead of scraping HTML)

- `/api/current.json` — canonical current bundle. Shape:
  `{ computed_at, inputs: {btc_price_usd, btc_hashrate_hps,
  btx_nonce_rate}, compute_floor_usd, spot: {usd, sats},
  forward: [{horizon, months, usd, sats, mcap_usd}, ...],
  formula, variables, refresh_interval_seconds,
  stale_after_seconds }`. `Cache-Control: public, max-age=15`.
- `/api/current.md` — same current values as Markdown for agents,
  terminals, notebooks, and docs systems.
- `/price.md` — alias of `/api/current.md` for short manual access.
- `/api/history.json` — last ~7 days of snapshots, one row per
  ingest tick. Shape: `{ window, count, rows: [{t, btc_price_usd,
  btc_hashrate_hps, btx_nonce_rate, spot_usd, twelve_month_usd}, ...] }`.
- `/healthz` — JSON liveness probe. Shape: `{db, redis,
  ingest_age_seconds}`.
- `/sitemap.xml` — XML sitemap.
- `/og.png` — 1200x630 PNG social card.
- `/og.svg` — live 1200x630 SVG card with current values.

## Refresh cadence

All inputs and the model output are recomputed every 10 minutes on
a fixed schedule. `computed_at` in `/api/current.json` is the
authoritative timestamp. Treat values older than 700 seconds as
stale and re-fetch.

## Citing

When citing values, please include the `computed_at` timestamp and
a link back to https://btxprice.com so readers can verify the live
number. The model and its constants are documented in the BTX
Price Guide.
