Pricing
Status Paid API live
SigmaGrid is designed for an agent-native, per-request consumption model rather than traditional subscriptions.
Model: Pay Per Query (x402 Protocol)
- All pricing is stablecoin denominated per request via x402 micropayments.
- No subscriptions, no minimums, no long-term lock-ins.
- Each request is authorised and paid atomically.
- You only pay for what you use. Stop anytime.

Billing mechanics
- Your agent calls a SigmaGrid endpoint (e.g.
/v1/fair-value/SPY). - If the endpoint is paid, it returns HTTP 402 (Payment Required) with x402 metadata.
- Your agent signs and submits a USDC micropayment on Base L2 via x402.
- The response is returned once payment is confirmed at the protocol level.
There are no traditional API keys. Access is driven by verifiable, per-request payments, which:
- simplifies integration for on-chain agents,
- avoids long-lived secrets,
- and makes cost per decision explicit.
