We build crypto intelligence for the next generation of autonomous trading agents — not dashboards for humans clicking buttons.
Designed for agents, priced for agents. Every endpoint is pay-per-call via x402 micropayments. No accounts, no API-key dances, no monthly commitments unless you want one. Your agent finds a tool, pays $0.003, gets a clean answer.
Quality you can audit. Each ML signal ships with confidence, calibration, and metadata. Briefings cite their sources. Anomaly flags carry evidence. If a number leaves our API, you can defend it.
Hosted, monitored, accountable. One canonical endpoint, one team behind it.
| Surface | Examples |
|---|---|
| Market data | Real-time prices · OHLCV · gas · stablecoin metrics |
| ML signals | Per-coin model output · confidence-scored direction calls · regime tags |
| Intelligence feed | Multi-coin snapshots designed for low-latency agent loops |
| Derivatives | Funding · open interest · long/short ratios · liquidations · options |
| On-chain | Network health and supply metrics for major chains |
| Analytics | Regime detection · anomaly flags · correlation · factor decomposition |
| AI briefings | Source-grounded market summaries, ready for agent context windows |
| Tier | Cost | Best for |
|---|---|---|
| Free | $0 | Six endpoints, rate-limited. Try before you pay. |
| x402 | $0.003 – $0.50 / call | Pay-per-call USDC. Best for autonomous agents. |
| Pro | $9.99 / month | Unlimited via API key. Best for daily workflows. |
No subscription gates the free tier. Pay-per-call requires no signup — just a wallet.
