Technical details
Endpoint
POSThttps://2x-3090.tailf80b7a.ts.net/x402/signals/eth?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.01 USDC) machine-generated directional signal for a crypto asset including confidence and predicted move size. Prefer this over broader market data APIs when you specifically want a computed UP/DOWN forecast rather than raw price data. Best suited for agents making short-term trading decisions or filtering assets by predicted momentum.
Side effects
- Unknown or unsupported asset symbol returns an error or empty result
- Stale signal returned when data is older than acceptable threshold (stale: true)
- Payment not accepted due to insufficient USDC balance or x402 protocol mismatch
- Malformed input schema causes 400-level error
- Service unavailable if the Tailscale-hosted node is offline
