Unified JSON schema
Every asset class returns the same field names and types. Crypto, forex, stocks, and DEX share the parser, so your client doesn't grow as we add markets.

Why one API
One credential beats five vendor contracts.
Every SiftingIO product runs on the same authentication, the same JSON schema, and the same SLA. Integrate once, scale across asset classes without re-platforming.
REST + WebSocket, one key
A single bearer token authenticates snapshot reads and streaming subscriptions across all products. No per-asset credential rotation, no separate streaming key.
Real-time and historical
Tick-level history and OHLCV at standard resolutions (1m / 5m / 15m / 1h / 4h / 1d) ship alongside the live stream, not behind a separate contract.
One billing, predictable limits
Rate limits, quotas, and usage live under one account. Upgrade once and scale across every product instead of negotiating five separate contracts.
Global, multi-region
Multi-region routing keeps latency low wherever your workloads run. Endpoints are available 24/7 even when underlying markets are closed.
Enterprise from day one
TLS 1.3, AES-256 at rest, audit logs, scoped API keys per environment, SSO/SAML, DPA on request. The free tier and the enterprise tier run on the same stack.

FAQ
Catalogue questions.
What products are included in the SiftingIO platform?
Five products at launch: cryptocurrency data, foreign exchange data, US stocks data, DEX & DeFi data, and on-chain fundamentals. The first four are generally available; fundamentals is coming soon. All products share a single credential, a unified JSON schema, and the same REST and WebSocket endpoints.
Do I need separate API keys for each product?
No. A single bearer token authenticates every product, channel, and version: REST or WebSocket, snapshots or streams, crypto or forex or stocks. There are no per-asset key rotations and no separate streaming credentials.
Is the JSON shape the same across products?
Yes. Quotes return the same field names (symbol, price, bid, ask, spread_bps, volume, change_24h, ts) across crypto, forex, and stocks, with asset-specific extensions where relevant (e.g. venue counts for crypto, fee tiers for DEX pools). One parser handles all asset classes.
Are real-time and historical data both included on every product?
Yes, for the four generally-available products. Tick-level history and OHLCV at 1m, 5m, 15m, 1h, 4h, and 1d resolutions ship alongside the live REST and WebSocket endpoints. History is not gated behind a separate contract.
How is pricing structured across multiple products?
All products share a single account, a single set of rate limits, and a single billing relationship. The free tier is generous enough to evaluate any product; paid tiers scale linearly with usage. Enterprise plans bundle volume discounts and net-30/60 invoicing across the entire catalog rather than per-product.
Can I redistribute the data inside my product?
Redistribution and display use are governed by your subscription tier and the SiftingIO Terms of Service. Standard plans permit display in your end-user product; redistribution as raw feeds, B2B sublicensing, and high-volume display use require an enterprise agreement. See the disclosures page for full terms.
What's on the roadmap beyond the launch catalog?
On-chain fundamentals (TVL, supply, holder counts, protocol-level KPIs) is the next product to ship. Crypto perpetuals and futures are on the roadmap as each market meets our quality bar. New asset classes are added as their data sources mature; subscribe once and new data arrives under the same credential.
Do you have enterprise controls for procurement and security?
Yes. SSO and SAML 2.0, SCIM provisioning, role-based access control, scoped API keys per environment, exportable audit logs, TLS 1.3 in transit, AES-256 at rest. Procurement support includes standard DPAs, custom MSAs, security questionnaires, and annual invoicing.
