Inputs
- Number of endpoints
- Average price per request (USDC)
- Estimated requests per month
Outputs
- Gross monthly revenue
- Net monthly revenue (your wallet)
- Annual run rate
Methodology: how we calculate
The calculator is intentionally transparent. Every number comes from the same three formulas. There are no hidden multipliers, no "industry average" fudge factors, and no projection curves.
- Gross monthly revenue =
average price per request × monthly requests. This is what your API earns before any fees. Pricing is per call in USDC; we sum all endpoints' contributions assuming the average price you provide. - Platform fee: none. Providers keep 100% of every x402 settlement. USDC routes directly from the paying agent to your own wallet via the CDP Facilitator. PayAPI Market never takes a cut on-chain and never holds your funds.
- Net to your wallet =
gross. There is no per-request fee and no listing fee, so net equals gross.
We do not model: chargebacks (there are none - payments are on-chain), refunds (servers can choose to issue them but most don't), gas fees (Base L2 is sub-cent and the agent pays them), USDC off-ramp fees (varies by exchange, typically 0.5–1.5%), or income tax (varies by jurisdiction).
Worked examples
Property data API: 24 endpoints, $0.002 average, 50,000 req/month. Gross $100/mo, and you keep all of it: $1,200/yr.
Crypto pricing API: 15 endpoints, $0.001 average, 500,000 req/month. Gross $500/mo, and you keep all of it: $6,000/yr.
Geocoding at scale: 5,000,000 req/month at $0.0005. Gross $2,500/mo, and you keep all of it: $30,000/yr.
