Starting with DePIN Market Data
What You Can Do with a Free Key
The catalog is browsable keyless — no key needed: hit /v1/networks, /v1/network/, /v1/supply, /v1/market, /v1/revenue, /v1/provenance directly. Registering (free, instant) adds $5 in credits and a key for the account surfaces — balance, POST /v1/credits/purchase (buys a data product inline) and top-ups. Note: the anonymous and free-tier views both serve a 40-network rotating sample of the catalog; the full breadth comes with a paid subscription tier, not with credits. You can:
- Browse the catalog to see all networks and which have live data.
- Pull supply telemetry for the networks you care about.
- Inspect provenance on any value via its
verify_url. - Compare canonical concepts across networks in a single query.
DePIN market data — supply, market cap, revenue, network health — is one of the fastest-moving data categories in crypto. But getting started shouldn't require a sales call or a contract. Here's how to get a free DePIN market data API key and start querying in under ten minutes.
Step 1: Get a Free API Key
Kairos Signal gives new registrants $5 in free credits — enough to explore the platform thoroughly. No credit card required.
Option A — Register via API (developer-friendly):curl -X POST "https://kairossignal.com/v1/credits/register" \
-H "Content-Type: application/json" \
-d '{"email": "[email protected]"}'
Either way you'll get an API key attached to your free credit balance.
What the Free Tier Includes
The catalog is browsable keyless — hit /v1/networks with no signup at all. A free key (instant, unconditional) adds $5 in credits for purchasing data products inline via POST /v1/credits/purchase — roughly 1,000 basic queries. The key authenticates your account surfaces; it does not change your data tier — anonymous and free-tier views both serve a 40-network rotating sample, and tier-gated views stay 402 until a paid subscription tier. That is enough to evaluate the API against your actual use case: browse the catalog, pull supply telemetry, and inspect the provenance envelope on any value. No credit card, no sales call, no time limit on when you use the credits.
From Free Key to Production
The free tier is a starting point, not a ceiling. When you need the full API — all REST endpoints, the MCP server, and Bitcoin-anchored provenance across every series — the $199/mo design-partner tier locks in lifetime pricing and includes production-level access. Because the integration surface is identical whether you are on the free tier or a paid plan, the code you write today works unchanged when you scale up.
How to Use the Free Credits
The fastest way to validate the API is to run the core queries yourself:
# Browse the full catalog with coverage tiers
curl "https://api.kairossignal.com/v1/networks" -H "X-API-Key: "
Pull supply telemetry for a specific network
curl "https://api.kairossignal.com/v1/supply?network=akash" -H "X-API-Key: "
Inspect a value's provenance
curl "https://api.kairossignal.com/v1/provenance" -H "X-API-Key: "
Every response carries source, as_of, verify_url, and freshness_verdict — so you can independently confirm any number before trusting it.
Step 2: Explore the Catalog
Kairos Signal catalogs DePIN networks and labels which carry live data and which expose first-party supply telemetry. Start by listing what's available:
curl "https://kairossignal.com/v1/networks" \
-H "X-API-Key: YOUR_API_KEY"
This returns the full network catalog so you can see which networks have supply, market, and revenue data before you build.
Step 3: Query Market and Supply Data
Once you have a key, pull market data for any network:
# Market data (price, market cap, liquidity)
curl "https://kairossignal.com/v1/market?network=helium" \
-H "X-API-Key: YOUR_API_KEY"
Supply telemetry (registered/active capacity, utilization)
curl "https://kairossignal.com/v1/supply?network=filecoin" \
-H "X-API-Key: YOUR_API_KEY"
Revenue data (protocol fees, DC burn)
curl "https://kairossignal.com/v1/revenue?network=helium" \
-H "X-API-Key: YOUR_API_KEY"
Every value returns with a verify_url and declared units, so you can confirm the source before building on it.
Step 4: Scale When Ready
The free credits let you validate your integration. When you're ready to scale, pricing is transparent — $0.005–$0.02 per query with clear tiers ($20 and $99 plans, and a $199/month design-partner tier). You only pay for live, verifiable data.
You're Live in Minutes
That's the whole onboarding flow. No contract, no credit card, no sales process — just a key, $5 in credits, and a normalized API across the live networks.

This is a data product. Kairos Signal publishes no trading signals or accuracy claims. All values are measured facts with verifiable provenance.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.
