# x402-paid-Service Generic API Executor (iholt)

> x402-paid-Service Generic API Executor (iholt) is a paid API for AI agents from x402-paid-service.iholt.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Accepts a generic HTTP sub-request payload and executes it as a paid API call via the x402 micropayment protocol for $0.01 USDC

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 x402-paid-service-generic-api-executor-iholt-a5119abf -d '<json body>'
```

Example prompt: Execute a paid JSON POST request through the x402 service at iholt.workers.dev — send a body of {"query": "hello world"} as a JSON body type using the HTTP method POST.

## When to prefer this

Use this endpoint when you need to execute a generic HTTP POST, PUT, or PATCH sub-request through an x402 micropayment-gated proxy for $0.01 USDC per call, especially in agentic workflows that require metered, pay-per-use API access via Cloudflare Workers infrastructure.

## Known failure modes

- Payment not settled — 402 Payment Required returned if x402 handshake fails
- Missing required 'input' field — 400 Bad Request
- Invalid method enum (only POST, PUT, PATCH allowed) — validation error
- Unsupported bodyType value — schema validation rejection
- Downstream service unreachable — network or timeout error
- Malformed JSON body — parse error returned

## How this service works

Discovery tier — generic paid API call

## Output

The agent receives the response from the proxied HTTP call, including any output object returned by the downstream service, as specified by the optional output schema in the request.
