## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability toll402-gateway-aggregated-x402-tool-endpoint-27b7fea1 -d '<json body>'
```

Example prompt: Call this Toll402 gateway endpoint to execute a tool from the aggregated x402 marketplace — pay $0.00115 USDC per call from my wallet, no API key needed, just dispatch the request with the right tool parameters.

## When to prefer this

Choose this endpoint when your agent needs to invoke one of Toll402's 2,000+ aggregated tools on a pay-per-call basis in USDC with no subscription or API key setup. Ideal for prototyping, low-frequency tool calls, or multi-tool pipelines where a single wallet and gateway simplifies orchestration. Prefer alternatives if you need deterministic SLA guarantees from a specific upstream provider directly.

## Known failure modes

- Payment rejected or insufficient USDC balance — HTTP 402 with payment details
- Invalid tool path or unrecognized endpoint ID — 404 or error JSON
- Tool backend unavailable or timed out — 502/504 from upstream
- Malformed request parameters for the target tool — 400 with validation error
- x402 wallet not configured or signature invalid — authentication error

## How this service works

The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.

## Output

Returns the structured output of the underlying tool or service invoked through the Toll402 gateway — format varies by tool but is typically JSON. May include the tool's direct response, metadata about the call, or an error message if the tool or payment failed.
