How this service works
Single answers, each paid on its own over x402. Guide: https://www.flyaiworld.com/x402-api.md
Output
A single AI-generated text answer returned after successful x402 micropayment authorization; the agent receives the answer payload in the response body after the $0.03 USDC charge is processed.
Example use cases
On-demand AI research query
“I need a quick AI answer about Ethereum staking APY trends — use my wallet 0xAbC123... to pay per request through fly.ai so I'm not locked into a subscription.”
Automated agent data lookup
“My agent needs to query fly.ai for a one-off AI answer about token liquidity for address 0xDEF456... — just pay the 3-cent fee per call and return the response.”
Developer testing pay-per-use AI
“Send a test question to the fly.ai x402 endpoint using wallet 0x789GHI... and charge the $0.03 USDC fee, I want to see how the pay-per-request model works before building it into my app.”

Endpoint
POSThttps://flyai-x402.fly.dev/token/%7Baddr%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need single, one-off AI-generated answers without committing to a subscription, and when you are operating in a context where x402 micropayment support is available. Ideal for agents that need occasional AI lookups billed per-use in USDC, or for developers testing pay-per-request AI economics on-chain.

- Insufficient USDC balance — wallet lacks funds, transaction rejected
- Invalid or malformed address parameter in URL path — returns 400 Bad Request
- Network or provider downtime on fly.dev infrastructure — returns 5xx error
- Rate limiting or abuse detection — request rejected without charge
