How this service works
onegate is a set of pay-per-call x402 endpoints for AI agents. It includes a preflight checker that verifies an x402 seller before your agent pays it, on-chain swap flow feeds with wallet attribution, single-use action leases with signed receipts, and an MCP server. No account, no API key.
Output
A JSON object with: ok (boolean success flag), flow object containing buys (integer), sells (integer), netflow_usd (signed float, negative = net selling), and unique_buyers (integer); anchor object with the block number used as reference; charged (boolean indicating payment was processed); and first_call (boolean).
Example use cases
Token momentum check before trade
“Look up the buy/sell flow for 0x532f27101965dd16442E59d40670FaF5eBB142E4 on Base over the last 30 minutes — is it net positive or negative flow, and how many unique buyers have there been?”
DeFi bot monitoring token health
“Every hour, check the token flow for 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Polygon (eip155:137) over a 60-minute window and alert me if net flow drops below negative $10,000.”
Suspicious token activity investigation
“I think this token contract 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Arbitrum (eip155:42161) might be getting dumped — can you check the last 90 minutes of buy/sell flow and tell me the net USD flow and unique buyer count?”
Technical details
Endpoint
GEThttps://onegate.biz.id/v1/flow?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need rapid, pay-per-call on-chain token flow analytics without an API key or account setup. Ideal for agents that need to check trading momentum or net flow for a specific EVM token contract on Base, Polygon, or Arbitrum with a configurable time window, and want to pay micro-amounts in USDC per call via x402 rather than maintain a subscription.
Side effects
- Invalid or malformed token address returns an error — must be 0x + 40 hex characters
- Unsupported CAIP-2 network identifier returns an error — only eip155:8453, eip155:137, eip155:42161 supported
- Window value outside 1–1440 range is rejected
- Payment failure via x402 results in 402 response and no data returned
- Token contract with no on-chain activity may return zero counts with ok:true
- Network congestion may cause stale anchor block data
