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
Returns the current facilitator status of the given merchant URL, indicating whether it is active, reachable, and capable of processing x402 USDC payments on Base or USDG on Robinhood Chain. May include signed receipt or payment reconciliation metadata.
Example use cases
Pre-flight payment gateway check
“Before my agent sends any USDC to https://api.datavendor.io/v2/prices, can you verify that its x402 facilitator is online and ready to accept payments?”
Debugging failed agent payment
“My autonomous agent failed to pay https://tools.aiservice.com/endpoint — can you check the x402 facilitator status on that URL to see if it's reachable or down?”
Monitoring merchant uptime for agent fleet
“Check whether the x402 facilitator at https://merchant.example/v1/quote is currently active so I know if my agent fleet can safely route payments there today.”
Technical details
Endpoint
POSThttps://api.tollex.org/tools/x402_facilitator_status?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or orchestration system needs to verify that a specific x402-compatible merchant URL is live and accepting USDC payments before committing to a transaction. Prefer this over generic HTTP health checks when x402 protocol compliance and payment readiness (not just HTTP reachability) must be confirmed. Especially useful as a pre-flight step before autonomous agent payments to avoid wasted gas or failed transactions.
Side effects
- Invalid or malformed URL returns a validation error
- Merchant endpoint is unreachable or offline — returns inactive/error status
- URL does not implement x402 protocol — returns unsupported or unknown status
- Network timeout if merchant server is slow to respond
- URL scheme not http/https — rejected by input schema pattern validation
