About agentshelf.syntexa.ch

Is agentshelf.syntexa.ch safe to pay?

Be careful. 1,253 of agentshelf.syntexa.ch's endpoints are rated Avoid right now: they were down a lot, took a payment and didn't deliver, or changed payout wallet without explanation. Check the specific endpoint before paying it.

How are these grades made?

Lumière PayCheck checks every endpoint about every 30 minutes: does it answer with a valid x402 quote, is the price and payout wallet stable. Then we pay some of them for real and check the response against what the listing promised. Failures are re-tested before they count. How it works.

Can my agent check agentshelf.syntexa.ch before paying?

Yes, for free. Call check_payment (API or MCP) with the endpoint, amount and payTo from the 402 quote, and pay only if it returns allow. Check an endpoint now.
