API & MCP
Read it from code
JSON over HTTPS, no key needed: 60 requests per minute per IP. Every number comes with the transactions behind it.
REST
GET /api/v1/launch/<mint>- One launch: labels with reasons, slot-0 buyers with class, rule and proving transactions, early slots, failed attempts, first-hour and 24-hour outcomes. example (test vector)
GET /api/v1/dev/<wallet>- A creator's record across launches, recurring linked wallets with proofs. An unknown wallet queues a 30-day backfill.
GET /api/v1/daily/<YYYY-MM-DD>- One UTC day: shares per label, biggest linked buy, cleanest dev, ready-to-copy text. Without a date: today.
GET /api/v1/feed?since=<unix>&label=&min_mcap=&has_website=1- Newest analyzed launches; pass
next_sinceback assince. GET /api/v1/stats,GET /api/v1/status- Today's numbers; indexer status, gaps and coverage.
Add ?demo=1 to any of these to get the synthetic test vectors.
