A token is one metered credit that works across the whole platform — the Signals API, Delta Agent, satellite imagery, reports, and MCP. Here is exactly what each operation costs.
A token is Off-Nadir Delta's single metered usage credit. One balance covers satellite tiles, the Signals API, Delta Agent, assessments, reports, and MCP. Credits are deducted by operation. Tile requests, imagery searches, assessments, monitoring runs, and Analyst questions have different costs. Estimated and maximum costs are shown before execution. Browsing the Watchfloor, the daily brief, and checking your balance are free. Tokens reset monthly; purchased packages last 365 days. Free tier available.
Per-action metered costs. These are the same figures the API and app charge — the app and the API never disagree. For subscription prices and monthly allocations, see Pricing.
| Operation | Tokens | Notes |
|---|---|---|
| View a satellite tile (Sentinel-1 SAR, Sentinel-2, NISAR, VIIRS) | Meteredby pixels × bands × processing | A fraction of a token for a standard tile. A map viewport loads many tiles as you pan and zoom; higher zoom, larger areas, more bands and index math cost more. Tiles already cached in your browser are free. Your balance and what each action cost are shown as you go. |
| NISAR scene preparation | 1per new area converted | NISAR products are large archives rather than tiles, so the area you select is converted before it can be drawn. Viewing the same area again is served from cache and costs nothing. |
| Change-detection (difference) analysis | 10per run | Server-side change detection between two dates. |
| Ship detection | 5per run | SAR vessel detection over an area. |
| Area monitoring | 2 + 0.5per check + per new scene | A catalog check per trigger, plus each newly processed scene. |
| Operation | Tokens | Notes |
|---|---|---|
| Delta Agent question | 5–123per question | Metered from the work the question actually did — light questions cost the floor, heavy tool-using ones the cap. |
| Delta Agent — deep mode | up to 415per question | Opt-in extended-reasoning runs with wider budgets. |
| Signal assessment (Assess) | 5 / 15quick / deep | AI remote-sensing deep-dive for a single signal. |
| Operation | Tokens | Notes |
|---|---|---|
| Daily report PDF export | 5per document | Assembled from the persisted daily brief. Reading reports on screen is free. |
| Operation | Tokens | Notes |
|---|---|---|
| Signals query — query_signals | 3per page (≤500 signals) | GET /api/v1/signals. |
| Single signal by ID | 1per call | GET /api/v1/signals/{id}. |
| Stats & hotspots — query_stats / query_hotspots | 1per call | Aggregated roll-ups. |
| Imagery catalog search — search_imagery | 2per call | GET /api/v1/imagery. |
| Imagery plan for one event — plan_event_imagery | 4per call | Runs a SAR and an optical catalog search, once each. |
| Satellite passes — predict_satellite_passes | 2per call | When a place can next be imaged, and by which satellite. |
Delta Agent and Assess are metered from the actual model work each run performs, so real costs land within the ranges shown. See the API reference and MCP docs for per-endpoint details.
Reading the Watchfloor, Signals, and the daily brief on screen is free. Spend tokens only when you deep-dive: an assessment, the Agent, or an API pull.
Zoom directly to your target area instead of panning around — each new area loads new tiles. Cached tiles never re-charge.
A single query_signals page returns up to 500 signals for a flat cost. Filter server-side and page with the cursor instead of many small calls.
The Agent is metered by the work it does. Specific, well-scoped questions cost near the floor; open-ended multi-tool research costs more.
