01 · Products
Market data for every developer, team, and business.
One API key works across every asset class and channel: REST or WebSocket, free tier or enterprise, with the same JSON schema and no separate contracts.
Real-time crypto, with full history.
Tick-level streams and historical OHLCV across major and mid-cap tokens. Aggregated and de-duplicated across multiple venues so you stop stitching feeds yourself.
TVL, supply, and protocol metrics.
On-chain fundamentals (TVL, circulating supply, holder counts, and protocol-level metrics) under the same credential and schema. Coverage expands as each dataset meets our quality bar.
02 · API
Same schema. Every asset, every channel.
One API key for REST and WebSocket. Every symbol, crypto or forex, returns the same fields in the same shape, so your parsing code doesn't grow every time we add a market.

}03 · Capabilities
What ships on day one.
Production primitives, not a demo. The free tier and the enterprise workload run on exactly the same stack.
REST + WebSocket
One API key across both channels. Pull a snapshot with REST or stream trades and quotes over WebSocket, same auth, same schema.
Unified JSON schema
Crypto and forex share the same fields, types, and naming. New asset classes inherit the shape, so your parsers don't grow with our catalog.
Historical depth, included
Tick-level history, OHLCV candles, and minute/hour/day backfill for research and backtesting. Not gated behind a separate contract.
Multi-venue aggregation
Crypto prices aggregated across major exchanges and de-duplicated. One canonical view, so you stop stitching feeds yourself.
Predictable rate limits
Generous defaults, transparent overage, and no surprise throttling mid-backtest. Limits scale with your plan, not with sales conversations.
Reliability-first
99.9% uptime SLA with continuous monitoring, health endpoints, on-call rotation, and a public status page with incident history.
Global by default
Worldwide currency pairs, international venue coverage, 24/7 crypto markets. Designed for teams building anywhere, not just one region.
On-chain on the roadmap
TVL and on-chain fundamentals are shipping as each dataset matures. Subscribe once, and new data arrives under the same credential.
04 · Use cases
Built for what you're actually building.
The same API powers a weekend backtest and a 24/7 live workload. Start on the free tier, scale up on the enterprise plan, without swapping clients.
algorithmic trading
Trading bots & quant strategies
Tick-level data that fits both a backtest and a live trading bot. One credential across REST for history and WebSocket for live, with no connector layer between research and execution.
research & dashboards
Research teams & data dashboards
Clean JSON, stable schemas, sensible defaults. Drop into a Jupyter notebook, a React dashboard, or a BI pipeline without writing a translation layer for each asset class.
risk & back-office
Risk, marking, and audit
Deterministic as-of pricing and historical snapshots for position marking, P&L attribution, and audit trails. Reproducible outputs, not moving targets.
wallets & fintech apps
Wallets, calculators & fintech
Embed live crypto prices and FX rates into wallets, payment flows, or end-user apps. Worldwide coverage, predictable costs, and no enterprise minimums.
plugins & integrations
Plugins, extensions & bots
Ship browser extensions, Slack bots, Discord bots, and no-code integrations that quote live prices. A single REST call or WebSocket subscription, no custom infra.
enterprise & infra
Enterprise data platforms
A cross-asset feed for internal platforms, data lakes, and feature stores. Stable schemas and versioned endpoints mean you integrate once, not every quarter.
05 · Enterprise
Production-ready, by default.
Commercial terms, controls, and support that your security, procurement, and platform teams expect, without the six-figure minimums or annual commitments to start.

DPA & custom contracts
Standard Data Processing Agreement available on request. Custom MSAs, NDAs, and security questionnaires supported for enterprise procurement.
Dedicated support
Named account manager, priority response targets, and a shared Slack or Teams channel on enterprise plans. Engineering escalation when it matters.

06 · FAQ
Questions devs actually ask.
Straightforward answers on coverage, reliability, pricing, and where we are on the roadmap.
What market data do you cover at launch?
Real-time and historical cryptocurrency prices across major exchanges, plus foreign exchange pairs sourced from institutional liquidity providers: majors, minors, and global exotics. TVL and on-chain fundamentals are on the crypto roadmap. New asset classes are added as each dataset meets our quality bar.
How do I authenticate the API?
A single bearer token on every REST and WebSocket request. The same API key works across all products, versions, and channels, so you don't juggle credentials per endpoint or re-issue keys when you add a new market.
What are the rate limits and quotas?
Free-tier defaults are generous enough to evaluate and run small workloads. Paid tiers scale linearly with your usage, with transparent overage pricing and no surprise throttling mid-backtest. Exact numbers are published on the pricing page and surfaced via response headers.
Do you offer historical market data?
Yes. Tick-level history and OHLCV candles are included, not an upsell. Backfill covers the ranges needed for research, backtesting, and audit. Historical depth is included on every plan that covers the underlying asset class.
Where does the data come from?
Cryptocurrency prices are aggregated across major exchanges and normalized into a single canonical view, so you get one feed instead of stitching venues yourself. Forex quotes are sourced from institutional liquidity providers with global coverage.
How stable is the API schema?
Breaking changes are versioned. Within a version, fields are never removed; new fields are additive. You can pin a version in the URL so parsing code doesn't drift as we ship new capabilities.
What's your uptime and latency commitment?
We operate to a 99.9% monthly uptime SLA with sub-100ms median response latency from our primary regions. Enterprise plans include service credits for SLA breaches. Live system status, incident history, and performance metrics are published on our public status page.
Can I use SiftingIO from anywhere in the world?
Yes. The API is globally distributed and usable from any region where commercial market data services are permitted. Forex coverage includes majors, minors, and exotics worldwide, not just one regional market. Multi-region routing keeps latency low wherever your workloads run.
What enterprise controls and procurement support do you offer?
SSO and SAML 2.0, SCIM provisioning, role-based access control, scoped API keys per environment, and exportable audit logs. For procurement: standard Data Processing Agreement (DPA), custom MSAs, security questionnaires, and annual invoicing with net-30/60 terms, POs, and bank transfer.
How is data encrypted and isolated?
All traffic is encrypted with TLS 1.3 in transit. Data at rest uses AES-256. Credentials and secrets are isolated per tenant and rotatable from the dashboard or API without downtime. Administrative access is logged and available in audit-log exports.
Who is this built for?
Individuals, startups, research teams, fintech apps, and enterprise platforms. SiftingIO is built to put production market data within reach of builders of any size. The same infrastructure powers the free tier and the enterprise workload.
Who handles billing and legal?
SiftingIO is a product of SaltingIO LLC (Wyoming, USA). Subscriptions, invoices, and legal contracts are processed through SaltingIO LLC. Enterprise customers receive custom MSAs and annual agreements on request.
