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 payment options available at the specified merchant URL, including accepted stablecoins (USDC, USDG), supported blockchain networks (Base, Robinhood Chain), payment protocols (x402), and any other merchant-specific payment configuration details needed before initiating a transaction.
Example use cases
Pre-purchase payment compatibility check
“Before my agent tries to call https://dataservice.example/api/enrich, look up what payment methods that merchant accepts so I can confirm it works with USDC on Base.”
Autonomous agent policy enforcement
“My agent wants to buy access to https://llm-tool.example/v2/complete — can you check what payment options are available there so I can decide if they match my spending policy?”
Multi-merchant payment option comparison
“I'm evaluating two API providers for my agent fleet — check the payment options for https://provider-a.example/quote so I can see which currencies and networks they support before committing.”
Technical details
Endpoint
POSThttps://api.tollex.org/tools/merchant_payment_options?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent or orchestrator needs to inspect what payment methods a specific merchant supports before committing to a purchase — especially in policy-gated or multi-currency environments where compatibility must be confirmed first. Prefer this over guessing or attempting a payment blind, particularly when operating under spending rules that restrict which networks or currencies are allowed.
Side effects
- Invalid or unreachable merchant URL returns an error or empty result
- Merchant URL does not implement x402 payment protocol — no options returned
- Malformed URL (not starting with http:// or https://) rejected by input validation
- Merchant server timeout leads to failed lookup
- URL exceeds 2048 character limit and is rejected
