# IP Geolocation API – Caller IP Lookup (myip)

> IP Geolocation API – Caller IP Lookup (myip) is a paid API for AI agents from ipgeo.payapi.market, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-17).

Returns geolocation data for the calling client's own IP address, including city, region, country, ISP, ASN, coordinates, timezone, and proxy/VPN/datacenter flags.

## Facts

- Endpoint: POST https://ipgeo.payapi.market/lookup/myip?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-17

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_oEnpI6dq58QJZb_jvbocI

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 ip-geolocation-api-caller-ip-lookup-myip-7ba0ce2c -d '<json body>'
```

Example prompt: What city and country is my current IP address located in, and is it flagged as a VPN or proxy?

## When to prefer this

Use this endpoint when you need to geolocate the machine or client making the current API call without supplying an explicit IP address — it auto-detects the caller's IP from request headers. Prefer it over batch or explicit-IP endpoints when you want self-introspection of the calling agent's network identity, including VPN/proxy/datacenter detection and ISP/ASN details.

## Known failure modes

- IP not found in geolocation database: 'found' field returns false with minimal data
- VPN/proxy detection fields may return null if not determinable
- Caller IP may be a NAT or load balancer IP rather than the true client if headers are not forwarded correctly
- Payment failure via x402 protocol results in 402 response before geolocation data is returned

## How this service works

IP geolocation, batch lookup, distance calculation, and caller-IP introspection with x402 payments.

## Output

Returns a JSON object with the detected IP address, city, region, country and country code, latitude/longitude, postal code, timezone, ISP name, ASN, organization, boolean flags for VPN/proxy/datacenter status, the upstream data source (e.g. ip-api.com), and how the caller IP was detected (e.g. request headers).
