# Get Basic Signals Bundle

`GET /api/signals/basic`

## Request

- Base URL: `https://api.zerogex.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.zerogex.io/api/signals/basic`
- Auth: HTTP bearer

Latest snapshot of all six Basic Signals in a single round-trip.

Basic Signals are continuous directional reads (clamped to `[-1, +1]`,
scaled to `[-100, +100]`) that complement the 6 MSI components and 6
Advanced Signals. They do **not** contribute to the composite MSI
(weight=0). Each entry is the most recent row persisted to
`signal_component_scores` by `BasicSignalEngine` each cycle.

Use this to populate a dashboard overview without firing six separate
requests. Click-through to the individual `/api/signals/basic/{name}`
endpoint for signal-specific decomposition and history.

**Signals (6, fixed order):** `tape_flow_bias`, `skew_delta`,
`vanna_charm_flow`, `dealer_delta_pressure`, `gex_gradient`,
`positioning_trap`.

**Params:**
- `symbol` (default `SPY`).

**Returns:**
```json
{
  "underlying": "SPY",
  "signals": {
    "tape_flow_bias":        {"score": 28.4,  "clamped_score": 0.284,  "direction": "bullish", "timestamp": "2026-04-22T18:55:00Z", "context_values": {...}},
    "skew_delta":            {"score": -12.7, "clamped_score": -0.127, "direction": "bearish", "timestamp": "...", "context_values": {...}},
    "vanna_charm_flow":      {"score": 0.0,   "clamped_score": 0.0,    "direction": "neutral", "timestamp": "...", "context_values": {...}},
    "dealer_delta_pressure": {"score": 45.1,  "clamped_score": 0.451,  "direction": "bullish", "timestamp": "...", "context_values": {...}},
    "gex_gradient":          {"score": -8.3,  "clamped_score": -0.083, "direction": "bearish", "timestamp": "...", "context_values": {...}},
    "positioning_trap":      null
  }
}
```

- `signals[name]` — `null` when the signal has never persisted a row
  for this symbol (first-deployment case). Render `"—"` in the UI, not `0`.
- `signals[name].score` — `clamped_score × 100`; `[-100, +100]`; 2 decimals.
- `signals[name].clamped_score` — raw `[-1, +1]`.
- `signals[name].direction` — `"bullish"` | `"bearish"` | `"neutral"` (sign of score).
- `signals[name].timestamp` — ISO-8601 UTC of the engine cycle.
- `signals[name].context_values` — signal-specific inputs/derived fields;
  same keys as the per-signal endpoint.

**Trader interpretation.**
- **All six aligned** (same sign) → high-conviction regime; follow the direction.
- **Flow side** (`tape_flow_bias`, `positioning_trap`) **diverging from structure**
  (`gex_gradient`, `vanna_charm_flow`) → potential reversal; flow leads structure intraday.
- **`0.0` during market hours** → signal *abstained* (below its data threshold),
  not "neutral conviction." Don't treat as a bearish read.

**Page design.** Six KPI tiles in a 3×2 grid. Each tile: direction chip
(green/red/gray), large `score` number, signal label. Click-through to
the `/api/signals/basic/{name}` detail view. Null tiles render as `"—"`.
Poll this endpoint together with `/basic/confluence-matrix` at cycle cadence.
