Pricing

All prices are in USDC (USD Coin on Base L2). Payments settle on-chain via the x402 protocol.

Domain pricing

We support 400+ TLDs. Prices are dynamic and calculated with a markup over wholesale cost.

Get live pricing from the API:

# All TLDs
curl https://api.bloomfilter.xyz/domains/pricing

# Specific TLD
curl https://api.bloomfilter.xyz/domains/pricing/io

Response:

{
  "tld": "io",
  "registration_price_usd": "34.99",
  "renewal_price_usd": "34.99",
  "transfer_price_usd": "34.99",
  "currency": "USDC"
}

Note

Multi-year registrations multiply the per-year price linearly. Prices may change as wholesale costs fluctuate — always check the endpoint for current pricing.
