Kairos Signal today announced the public availability of its DePIN Intelligence API, a data product providing verifiable telemetry across Decentralized Physical Infrastructure Networks (DePIN). The API catalogues DePIN networks and labels which carry live data — those with first-party supply telemetry read directly from each network's own API endpoint, and those with on-chain data only.
Unlike existing DePIN data aggregators that present derived or modeled estimates, every value served by the Kairos Signal API carries a verify_url pointing to the exact upstream source that produced it. Users can independently confirm any data point — supply counts, protocol fees, market valuations, and operational telemetry — without trusting the platform as an intermediary.
"Provenance or silence — that's the entire principle," said Daniel Smith, founder of Kairos Signal. "If we can't point you to the exact endpoint a number came from, we don't serve it. We'd rather omit a metric than present something we can't verify."
Bitcoin-Anchored Data Integrity
How to Start Using the API
Getting live is a three-step flow:
GET /v1/networks to see all networks and their coverage tiers (first-party, on-chain, catalog-only).verify_url to confirm the value at its source.# List the live catalog with coverage tiers
curl "https://api.kairossignal.com/v1/networks" -H "X-API-Key: *"
Pull supply telemetry for a network
curl "https://api.kairossignal.com/v1/supply?network=akash" -H "X-API-Key: *"
Verify a value at its source
curl "https://api.kairossignal.com/v1/provenance" -H "X-API-Key: *"
Agents can use the same data through our MCP server, which exposes the full catalog and query surface to autonomous workflows.
Each daily data batch is Merkle-rooted and timestamped to the Bitcoin blockchain via OpenTimestamps. This creates a tamper-evident audit trail: any historical data point can be cryptographically proven to have existed at a specific time, without relying on a trusted third party. The timestamp anchors are embedded in Bitcoin transactions and verifiable independently.
API Access and Pricing
The API is accessible via REST and MCP (Model Context Protocol) endpoints, designed for both human developers and autonomous AI agents. Pricing starts at $0.99 for the full network catalog and ranges up to $4.99 for complete supply telemetry snapshots across all 296 live networks. A design partner tier at $199/month provides full API access across all data tiers with a forever price lock.
New registrants receive $5 in free credits instantly and unconditionally at POST /v1/credits/register — no approval step, and no credit card required. The API also serves as an MCP endpoint for AI agents that use the Model Context Protocol standard, enabling autonomous agents to query DePIN infrastructure data programmatically.
What the API Covers
- Supply telemetry: First-party infrastructure metrics from 296 networks, including registered capacity, deployed capacity, and utilization rates
- On-chain revenue: Verified protocol fees and treasury inflows for 78 networks, read directly from chain state
- Market data: Price, market cap, and liquidity for 288 networks with on-chain market data
- Provenance disclosure: A dedicated endpoint documenting data freshness policies, staleness flags, and omission rules — absent metrics are never zero-filled
catalog_only so developers can filter them in a single line of code.
About Kairos Signal
Kairos Signal builds verifiable data infrastructure for the decentralized physical infrastructure economy. The company operates a data lake containing $2.32 trillion in federal contract records from USASpending.gov, 168,000 NOAA weather alerts, 122,000 USGS earthquake records, and 14,600 Federal Register entries, alongside its core DePIN network telemetry. All data products prioritize provenance-first design: every value traces to a checkable upstream source.

Get Started With DePIN Intelligence
Kairos Signal provides verifiable, provenance-first telemetry for DePIN networks, including first-party supply data read directly from a network's own API or blockchain. Every value carries a verify_url you can check yourself, and each daily batch is Merkle-rooted and anchored to Bitcoin.
Every API response is signed with ed25519 and timestamped. You can prove what was served and when, months later. That is what we mean by provenance-first.
