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 signed payment receipt confirming the capability was found, policy was satisfied, and payment in USDG on Robinhood Chain was completed, along with the capability's response data and transaction details for reconciliation.

Example use cases

Agent auto-buys a data enrichment tool

“My agent needs to enrich company data on the fly — find a capability that fits, make sure it's under my $10/day limit, pay with USDG on Robinhood Chain, and hand me back the signed receipt so I can verify the transaction.”

Policy-gated tool purchase for AI workflow

“I'm running an autonomous workflow that needs to call a sentiment analysis API. Let Tollex find one that matches, check my spending policy first, and pay with USDG — I need confirmation that everything was authorized before it proceeds.”

Reconcile uncertain agent payment with USDG

“My agent made a tool purchase that I'm not sure went through — can you use Tollex to reconcile that payment on Robinhood Chain with USDG and return a signed receipt confirming the final status?”

When to prefer

Choose this endpoint when your agent needs to autonomously discover and pay for API capabilities using USDG on Robinhood Chain specifically, with policy enforcement before any payment is committed. Prefer it over generic API marketplaces when you need x402-native payments, policy gating, and signed receipts for audit trails in an agent-operated context.

Side effects

Policy violation: requested capability exceeds agent's configured spending rules, request rejected before payment
Payment failure: USDG balance insufficient or Robinhood Chain transaction fails, no capability returned
No matching capability found: Tollex cannot find an API that satisfies the request criteria
Uncertain payment state: transaction submitted but not yet confirmed, reconciliation required
Invalid input schema: missing required fields (type, method, bodyType, body) returns 400 error
x402 protocol error: payment handshake fails, signed receipt not issued
