Pricing

Every query is priced by complexity — the sum of costs for each field you request. You only pay for what you ask for.

Cost per field

Cost per unit: 0.00002 USDC

Minimum charge: 0.002 USDC per query

Example calculation

graphql
{
  newTokens(limit: 10) {   # 5 units base
    tokens {
      symbol               # 0 units (free)
      price { usd }        # 3 units
      risk { score }       # 10 units
    }
  }
}
# Total: 18 units × $0.00002 = $0.00036 USDC

Getting the cost before paying

Send any query without a payment header. The 402 response body contains:

json
{
  "details": {
    "amount": "0.000360",
    "queryCostUnits": 18,
    "costPerUnit": 0.00002
  }
}

Your agent can read this and decide whether to proceed before signing any payment.

Developer API keys

During development, you can use credit-based API keys instead of x402. Each query deducts complexity units from your credit balance. See the Quickstart for usage.
