**Canonical:** https://apis.io/apis/snowsignals/snowsignals-api/

**Base URL:** https://snowsignals.io/v1  
**Documentation:** https://snowsignals.io/docs

SnowSignals API is one of 2 APIs that [SnowSignals](https://apis.io/providers/snowsignals/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Crypto and Market Data. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.

TrendVane daas API — metered, prepaid market-phase reads per currency and timeframe (boundary = settled last closed bar, updates = intra-bar), plus free unmetered metadata (phases, pricing model, server time) and a free BTC-derived phase-resolution statistics model. Auth is one of two mutually exclusive per-account apiKey methods (url query key, or a strictly-increasing nonce signature). The equivalent MCP surface at /mcp exposes the same reads as 8 tools.

## Operations (9)

| Method | Path | Summary |
|---|---|---|
| GET | `/api/phase/resolution-stats` | Public, unmetered: how each phase historically resolves, to help interpret a /phase read. |
| GET | `/api/notifications` | Read-only notification feed (unmetered). Overview = 10 most recent per category; drill-down = next 10 of one category. |
| GET | `/api/phases` | Public, unmetered metadata: the 12-value phase enum + labels + enabled TFs/currencies, plus an about-the-model summary and a definition card per phase. |
| GET | `/api/time` | Server clock in epoch ms; public, unmetered. Use it to keep your nonce ahead. |
| GET | `/user/balance` | The account's spendable/refundable balance + atom display (session or ApiKey auth). |
| GET | `/user/usage` | The indexed usage log (id-cursor paginated via `before`). |
| POST | `/user/deposit-now` | Prod the system to check for a deposit (session or ApiKey auth). |
| GET | `/api/phase/boundary` | Metered Phase-Event read: boundary (the last closed-boundary phase, deterministic truth), per currency×TF. |
| GET | `/api/phase/updates` | Metered Phase-Event read: updates (the intra-bucket phase on the timeframe's sub-cadence), per currency×TF. |
