Deterministic, verifiable financial data feeds for DeFi protocols and institutional platforms. We publish observable facts — not opinions. Every data point is independently reproducible.
Every feed is built from publicly observable data. No issuer cooperation required. No proprietary access needed. Fully reproducible.
Cross-venue funding rate composites, annualized basis indices, and volatility surfaces for BTC and ETH. Aggregated from 5+ CEX and DEX perpetual venues with deterministic methodology and cryptographic signing.
Observable onchain facts for tokenized U.S. Treasury assets — supply dynamics, holder concentration, transfer velocity, NAV staleness, and redemption flags. Facts, not opinions.
Our principles are structural, not aspirational. They determine what we will and won't publish.
We publish what we can independently observe and verify. No credit ratings. No risk scores built on inaccessible data. No opinions disguised as metrics. Every output is reproducible from public inputs.
Given the same raw inputs, our pipeline always produces the same outputs. Methodology version is embedded in every data point. Any change follows a 14-day notice period with shadow publishing.
Every published value is timestamped, fingerprinted (SHA-256), and cryptographically signed. Full audit trail from raw source data to published feed. We don't just claim accuracy — we prove it.
Funding rate definitions differ across venues. We maintain canonical per-venue field mappings, normalize all rates to 8-hour equivalents, and align timestamps to prevent garbage composites.
Once published and signed, values are immutable. If a source retroactively corrects data, the correction appears in the next interval only. Consumers can trust what was published, when.
All data sourced from public exchange APIs and onchain reads. No redistribution-restricted third-party feeds. No issuer cooperation required. Our independence is structural, not just policy.
Starting narrow with the most machine-legible assets. Expanding based on market demand and data quality.

Production API key, SLA activation, status page access. 14-day notice for any methodology changes.
We're onboarding anchor customers for both products. Request early access to shape feed specifications with us.
REST API for off-chain consumers. Automatic onchain delivery via Chainlink DataLink.
The Locify API provides deterministic, cryptographically signed financial data feeds. All responses include methodology version, venue weights, confidence flags, and Ed25519 signatures for independent verification.
Base URL:
https://api.locify.com/v1
All timestamps are UTC. All rates are decimal (0.000142 = 0.0142%). Annualized values use 365-day convention with 3x daily funding (365 × 3 × 8h rate).
All requests require an API key passed via the X-API-Key header. Keys are issued upon access approval.
X-API-Key: your_api_key_here
Rate limits: 100 requests/minute (Standard), 1,000/minute (Professional), unlimited (Enterprise). Rate limit status is returned in X-RateLimit-Remaining headers.

Locify, Inc. ("Locify," "we," "us") provides computed financial data feeds via REST API and Chainlink DataLink integration. Our feeds include perpetual funding rate composites, basis indices, volatility surface metrics, and tokenized asset operational signals.
Locify publishes computed data derived from publicly observable sources. While we employ deterministic methodologies and rigorous quality controls, we make no guarantee that our data is error-free. Specifically:
API access is granted on a subscription basis. Users agree to use the API within their approved rate limits, not redistribute raw feed data to third parties without written permission, and not misrepresent Locify data as their own proprietary output.
Service level agreements are defined per subscription tier. Scheduled maintenance occurs Sundays 06:00–07:00 UTC. In the event of SLA breach, remedies are limited to service credits as defined in individual subscription agreements.
We provide a minimum 14-day advance notice before any methodology change, accompanied by a shadow publishing period where both old and new methodologies run in parallel. Methodology version is embedded in every API response.
To the maximum extent permitted by law, Locify shall not be liable for any indirect, incidental, or consequential damages arising from the use of our data feeds, including but not limited to trading losses, liquidation events, or protocol malfunctions.
These terms are governed by the laws of the State of Delaware, without regard to conflict of law principles.
