Question 1

How do AI agents pay for API calls on Obolo?

Accepted Answer

When an agent calls your API, Obolo's proxy returns a 402 Payment Required response with price and wallet details. The agent sends a stablecoin payment (USDC, USDT, USD1, or PYUSD), Obolo verifies it on-chain, and the API response is delivered. The whole process takes seconds.

Question 2

Which stablecoins does Obolo support?

Accepted Answer

Four stablecoins: USDC (Circle), USDT (Tether), USD1 (WLFI), and PYUSD (PayPal/Paxos). PYUSD is available on Ethereum and Solana. Token availability varies by chain — for example, TRON supports USDT and USD1 but not USDC.

Question 3

Which chains does Obolo support?

Accepted Answer

Eight mainnet chains (Base, Solana, TRON, Ethereum, Arbitrum, Optimism, Polygon, BSC) plus eight testnets — one for every mainnet chain.

Question 4

What does the platform fee cover?

Accepted Answer

10% on all transactions. Automatically drops to 7% above $10K/month and 5% above $50K/month. Everything included at every level: payment verification, 8 chains, 4 stablecoins, OFAC screening, marketplace, analytics, off-ramp to 100+ countries, fraud detection. No subscriptions, no feature gates.

Question 5

Do I need to install an SDK to use Obolo?

Accepted Answer

No. The fastest way to start is our zero-code proxy — create an endpoint in the dashboard, point your API behind the proxy URL, and you're collecting stablecoin payments without touching your codebase. The provider SDKs (TypeScript, Python, Go, Rust) are for teams that want middleware-level control over the payment flow.
