# Orcpin Batch x402 Endpoint Reliability Check

> Orcpin Batch x402 Endpoint Reliability Check is a paid API for AI agents from orcpin.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns factual reliability measurements (uptime, valid-402 rate, latency, last status) for a batch of x402 endpoints in a single paid call.

## Facts

- Endpoint: GET https://orcpin.dev/v1/endpoint-reliability/batch
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/orcpin-batch-x402-endpoint-reliability-check-24962311
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ILb_pMZjlZDXyTQHX96Hi

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 orcpin-batch-x402-endpoint-reliability-check-24962311
```

Example prompt: Before I kick off my workflow, sweep all of these x402 endpoints for reliability stats — uptime, valid-402 rate, and latency — in one shot: https://api-a.example.com/data, https://api-b.example.com/prices, https://api-c.example.com/signals

## When to prefer this

Use this endpoint when an agent needs to pre-flight check multiple x402 endpoints in a single paid call before relying on them in a workflow. It is preferred over single-endpoint checks when you have 2+ x402 URLs to verify simultaneously, reducing round-trips and cost. Choose it over generic uptime monitors when you specifically need x402-protocol-aware metrics like valid-402 rate.

## Known failure modes

- Missing or malformed 'urls' query parameter returns a 400-level error
- Exceeding the server-configured per-batch URL limit results in rejection
- Non-x402 URLs may return incomplete or null measurements
- Payment not completed via x402 protocol results in a 402 response with no data
- Temporarily unreachable target endpoints may skew latency or uptime readings

## How this service works

Batch x402 endpoint reliability: factual delivery measurements (uptime, valid-402 rate, latency, last status) for an agent's whole tool list of x402 endpoints in one paid call. Endpoints with no stored history are probed live, so every billed URL returns real facts. Sweep every endpoint you depend on before relying on them. Billed per endpoint, with volume discounts at 10+/50+/100+ URLs. Facts only — not an endorsement or rating.

## Output

Returns a JSON object containing a count of checked endpoints and a results array where each entry includes factual delivery measurements — uptime percentage, valid-402 response rate, latency, and last observed status — for each submitted x402 URL, plus a schema_version and disclaimer.
