pricing

Pay per call. Fractions of a cent.

No subscription. No free tier. No account. Each endpoint quotes its price up front, sized to the cost of the underlying compute. Dynamic pricing applies where payload size, duration, or load varies. Settlement is direct, on-chain, in USDC on Base, Polygon, or Solana.

First-party endpoints. Community open.

Each cell shows the price range for that tier. Sell-side community endpoints have their own pricing set by their author. Counts hydrate from /v1/_meta.

Dynamic pricing where compute varies. Price adapts to load, time of day and rolling demand. The 402 quote always tells you the exact amount before you pay.

questions

Pricing FAQ

How does dynamic pricing work?
Endpoints with variable compute use an adaptive price function tied to rolling load and demand. The 402 quote always returns the exact amount your wallet must pay — there is no surprise after the fact. Variation is typically within ±15% of the base price. See per-endpoint flags in /v1/_meta.
Is there a free tier or trial?
No. Per-call pricing is the same for everyone. Fund a wallet with $1 of USDC and that's roughly 2 000 trivial calls, 200 invoices, or 100 vision captions of runway. Free probes exist for /v1/_meta, /v1/_health, /v1/_audit only.
Are there volume discounts?
No. Per-call pricing is identical regardless of volume. We don't gate cheaper pricing behind enterprise contracts — the cost basis is the underlying compute, not the buyer's size.
How is sell-side pricing set?
Community endpoints (— live today) are priced by their author via atomic_price in 6-decimal USDC. tools402 takes 3 % paywall or 4 % proxy off the top. Choose your payout chain (Base, Polygon, Arbitrum, Optimism, Avalanche, or Solana) — paid in USDC there; cross-chain handled via CCTP. Settlement runs daily at 00:00 UTC, in USDC. A balance ≥ 1 USDC is paid at the next run (within 24h). A balance below 1 USDC carries over and accumulates across days until it reaches 1 USDC, then it's paid.
What about gas fees?
Gas cost depends on your payout chain — typically ~$0.005 per USDC transfer on Base. The buyer pays gas on their wallet's transfer (single confirmation). On the sell-side, tools402 absorbs gas on daily USDC payout transactions to your declared payout_chain.
Refunds or disputes?
Payment is verified on the request, not the response. If upstream fails after settlement, the call is retried with the same X-Payment for up to 60 seconds. Persistent 5xx returns the tx hash in headers — auditable on a block explorer. No off-chain refund mechanism by design.
