SolMachina SGP Checkpoint — Solana Epoch Progress & Slot Timing
x402
SolMachina SGP Checkpoint — Solana Epoch Progress & Slot Timing is a paid API for AI agents from api.solmachina.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Returns real-time Solana epoch progress, slot index, slot timing metrics, and ETA to epoch end for the current and recent epochs.

How this service works
Before an AI agent executes on Solana, it asks SolMachina: risk + a decision (EXECUTE/REVIEW/REJECT) + an SMRI score + a signed receipt, paid per call over x402 in USDC. Trust-first — cites every source, says 'unknown' over guessing. No account, no API key.
Output
Returns a structured JSON object with three sections: (1) 'latest' — current epoch number, slot index within the epoch, progress as a percentage, and total slots in epoch; (2) 'series' — count of data points and the most recent epoch transition (from/to epoch numbers); (3) 'measured' — average slot duration in milliseconds, ISO-formatted ETA for epoch end, and the baseline measurement window in hours.
Example use cases
Epoch end timing for DeFi automation
“I need to know when the current Solana epoch ends — give me the ETA in ISO format and the current slot progress percentage so I can time my staking action.”
Slot speed health check
“What's the average slot duration in milliseconds on Solana right now, and what's the baseline span being measured over?”
Epoch transition history review
“Pull me the last 50 series points from SolMachina's epoch checkpoint so I can see recent epoch transitions and track when the network crossed from one epoch to the next.”
Technical details
Endpoint
GEThttps://api.solmachina.com/v1/sgp-checkpointWhen to prefer
Use this endpoint when you need real-time Solana epoch timing data — specifically epoch progress percentage, slot duration metrics, or estimated epoch end time — without requiring an API key or account. Prefer this over generic Solana RPC calls when you want pre-computed, source-cited epoch intelligence with historical series context, paid per-call via x402 USDC.
Side effects
- Solana RPC node unavailability causing stale or missing data
- Invalid 'n' parameter (out of 1-200 range) resulting in a 400 error
- Payment failure via x402 if USDC balance is insufficient
- Network latency causing delayed epoch progress readings
