Where to get free DePIN network data in 2026 — the honest comparison

If you're building on DePIN data — a dashboard, a trading bot, an AI agent — you've hit the same wall everyone does: node counts, GPU supply, and utilisation numbers are scattered across 300+ network-specific APIs, each with its own schema, rate limits, and definition of "active node."

Here's the state of every free source, and what each one can't tell you.

1. Each network's own console API (free, authoritative, unstandardised)

Akash, Helium, Filecoin, Render, io.net and friends all publish their own dashboards. This is the ground truth — and it's exactly the problem:

• Different schemas per network. Akash counts networkCapacity.activeGPU; Helium splits Hotspots by band; Render reports by tier. Joining them into one panel means writing 100+ parsers.
• No history. Most consoles show only the current state. Try to backtest anything and you're stuck.
• Definitions drift. When "active" quietly changes meaning upstream, your panel breaks silently.

2. CoinGecko / CoinMarketCap (free, market data only)

Great for price, market cap, FDV. Useless for supply-side reality: zero node counts, zero GPU capacity, zero utilisation. You get the token data, not the network data.

3. Aggregators (DefiLlama etc.) — TVL only

DeFi TVL is not physical supply. None of the DePIN networks' actual infrastructure metrics (nodes online, GPU hours, storage capacity) are covered.

4. Kairos Signal (free tier, no key for verification)

The free /try endpoint returns 3 full networks + AI analysis preview, no key. Every value in the response carries three fields no other aggregator provides:

• source — which upstream API the number came from
• as_of — exact fetch timestamp
• verify_url — the upstream endpoint itself, so you can re-fetch and compare

Beyond the free tier: a machine-legible coverage spec (freshness + history depth per feed), and a Derivation Ledger that stores the raw upstream payload plus the hash of the collector code for every fetch — so any published value can be replayed from origin. Registration is free ($5 credits, no card).

The honest comparison

| Need | Network consoles | CoinGecko | Kairos free tier | |---|---|---|---| | One schema for 457 symbols | ✗ (100+ parsers) | ✓ but token-only | ✓ | | History | ✗ current-state | partial | daily snapshots | | Provenance | it IS the source | none | verify_url per value | | Replayable derivation | n/a | n/a | raw payload + code hash | | Cost | free, your engineering time | free | free to verify |

What to do next

Call GET https://kairossignal.com/try — zero setup.

Click any verify_url in the response and compare against the origin.

If the format works for you: POST https://kairossignal.com/v1/credits/register gets you $5 in credits and an API key in about five seconds. No card, no crypto, nothing to cancel.

Every number in our panels is measured, never modelled. Where a network publishes no data, we say so instead of estimating. Provenance or silence.
