# ResolveBots x402 Client Probe (Basic)

> ResolveBots x402 Client Probe (Basic) is a paid API for AI agents from resolvebots.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Probes and validates an x402 payment endpoint using a real paid request, returning a trust verdict, capability checks, and compliance receipt for the tested payment rail.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 resolvebots-x402-client-probe-basic-1189bc66 -d '<json body>'
```

Example prompt: Run a basic x402 probe on my endpoint using the base-exact facilitator and tell me the trust verdict, what checks passed or failed, and whether it's ready for launch.

## When to prefer this

Choose this endpoint when you need to empirically verify that an x402-enabled API endpoint correctly handles real paid requests on a specific payment rail (base-exact or Circle Gateway), rather than just checking static configuration. It is the right choice for pre-launch validation, debugging payment failures, or obtaining a shareable compliance certificate for an x402 commerce endpoint.

## Known failure modes

- Payment rail not recognized — invalid facilitator value returns an error
- Endpoint under test is unreachable or returns non-x402 responses — probe fails with descriptive verdict
- Insufficient USDC balance to cover the $0.10 probe fee — payment rejected before probe executes
- x402 facilitator infrastructure downtime causes probe to time out
- Malformed request body causes validation error before probe initiates

## How this service works

ResolveBots is the trust and launch layer for x402 commerce: a free public Trust Index, paid endpoint checks, readiness reviews, and managed launch seeding.

## Output

Returns a JSON object with an overall ok boolean, trust level string, detailed checks object showing which capabilities passed or failed, a verdict summary, detected features, payment metadata, a receipt object from the live paid probe, a limitation description, and optionally a certificate ID and verify URL for sharing compliance results.
