How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream response body and content-type from the rapid-x-com2 service, passed through transparently after the $0.01 USDC x402 payment is validated. The agent receives whatever the upstream API returns — JSON, text, or other content — without transformation.
Example use cases
Fetch live DeFi token price
“Use QuantaFlow to hit the rapid-x-com2 endpoint at /token/price with a GET request and query params {token: 'USDC', chain: 'ethereum'} — pay the per-call fee and give me whatever price data comes back.”
Query on-chain wallet balance
“Forward a POST request to /wallet/balance on rapid-x-com2 via QuantaFlow with a JSON body of {address: '0xABC...123', network: 'base'} and return the balance result.”
Retrieve DeFi protocol stats
“Route a GET request to /protocol/stats with query {protocol: 'uniswap', metric: 'tvl'} through the QuantaFlow x402 gateway for rapid-x-com2 and show me the response.”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/rapid-x-com2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call access to the rapid-x-com2 web3/DeFi upstream service via x402 micropayments and want to avoid subscription commitments. Ideal for agents that make infrequent or variable-volume calls to crypto/DeFi data tools and need on-chain-verifiable payment semantics.
Side effects
- Payment failure: insufficient USDC balance or wallet not configured for x402 causes 402 Payment Required response
- Invalid path: upstream returns 404 if the specified path does not exist on rapid-x-com2
- Upstream error: upstream service outage or timeout passes through as 5xx error
- Malformed query/body: upstream may return 400 if JSON body or query params are invalid
- Rate limiting: upstream may impose its own rate limits independent of payment
