Technical details
Endpoint
POSThttps://api.sigmagrid.app/v1/alpha-snapshot/%7Bticker%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time quantitative alpha signals for a specific ticker to inform algorithmic or discretionary trading decisions, especially when integrated into a micropayment-enabled agent workflow using the x402 protocol. Prefer this over static fundamental data APIs when recency and signal-based scoring matter.
Side effects
- Payment not included or insufficient — returns HTTP 402 requiring x402 payment
- Invalid or unrecognized ticker symbol — returns 4xx error
- Ticker not covered by SigmaGrid data universe — empty or error response
- Network timeout if signal computation exceeds latency budget
- Rate limiting if too many requests in a short window
