We're building three B2B tiers on top of the live /api/repos
+ signals stack. Drop your email on the tier you'd use — we ship to early-access
subscribers first, with founder-priced annual contracts before the public price kicks in.
/api/repos? It stays free. The B2B
tiers add enriched data, webhooks, higher rate limits, and contractual SLAs.
Yes. Free tier: browse all markets, read public API, watch charts, get delayed data. Standard trading fees only apply when you actually place a trade. No signup fee, no subscription needed.
USDC on Solana is the only settlement currency. Deposit through Coinbase Onramp (fiat card) or send USDC directly from another wallet. Withdrawals are USDC to any Solana address.
No. Fees only on successful settlement. If a trade fails (solvency check, safeguard trigger, connectivity), nothing is charged. Quote endpoints /api/repo/{t}/quote return non-binding estimates — zero fee.
Single trades above $100 notional get 0.25% rebate on the fee. Doesn't stack — exclusive to large-order tier. Size threshold adjusts with market volume (re-published monthly).
Yes. Upgrade any time — prorated. Downgrades apply at next billing cycle. Enterprise contracts are annual minimum with quarterly review options.
Phased rollout: early subscribers get features first. Priority order published in /status.html. Current Plus queue: reduced fees (ready), early momentum alerts (Week 2), watchlist (Week 3).
