How this service works
Tollex lets software agents buy APIs and tools under rules you set: it finds a capability that fits, checks your policy before anything is signed, pays with x402 in USDC on Base or USDG on Robinhood Chain, reconciles uncertain payments and returns a signed receipt.
Output
A JSON object containing: an array of active payment rails (each with id, stablecoin symbol, network chain ID, and acceptingNewPayments flag), a map of chain IDs to their latest block numbers, an overall status string ('ok'), the service name, and a paidWith object showing which asset address, amount in base units, and network were used for this very call.
Example use cases
Pre-purchase rail health check
“Before you buy that data API for me, ping Tollex and confirm its payment infrastructure is up and accepting USDC on Base — I don't want you to attempt a purchase if the rails are down.”
Verify Robinhood Chain USDG availability
“Check whether Tollex is currently accepting new payments in USDG on Robinhood Chain and tell me the latest block number so I know the chain is live.”
Agent spending policy pre-flight
“My autonomous agent is about to start purchasing tools — first do a Tollex status check and return the full list of supported rails and stablecoins so I can configure its spending policy correctly.”
Technical details
Endpoint
GEThttps://api.tollex.org/v1/agent-check?utm_source=zero.xyzWhen to prefer
Use this endpoint as a pre-flight check before any Tollex-mediated API purchase: it tells you which stablecoins and chains are live without committing funds. Prefer it over querying blockchain RPCs directly when you need a single authoritative view of Tollex's accepted rails and real-time service health in one call.
Side effects
- Service outage returns non-ok status or network error
- Rail acceptingNewPayments set to false if chain is congested or paused
- Block number may be stale if a chain RPC is degraded
- Malformed properties query parameter may return 400 or empty response
- USDC payment of $0.0078 may fail if agent wallet has insufficient balance
