How this service works
Call when an agent needs whether a string is an IPv4 address. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/check-ip-ipv4 first.
Output
Returns a boolean or structured result indicating whether the submitted string conforms to the IPv4 address format (four dot-separated octets each in the range 0–255)
Example use cases
Validate user-submitted IP field
“A user just filled in our network configuration form with '10.0.0.256' as their server IP — can you check if that's actually a valid IPv4 address before I save it?”
Filter IP addresses by version
“I have the string '2001:db8::1' — is it an IPv4 address or something else?”
Sanitize ingested log data
“Before I process this log entry, I need to know whether '172.16.254.1' is a valid IPv4 address — can you verify that for me?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-ip-ipv4?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a definitive, deterministic IPv4 check without relying on an LLM's pattern-matching, especially in automated pipelines where correctness matters. Prefer the free sandbox endpoint `/v1/sandbox/check-ip-ipv4` first to avoid the $0.007 USDC fee; fall back to this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- Empty or missing value field returns an error
- Value exceeds maxLength of 20000 (unlikely for an IP, but enforced)
- Payment failure if USDC x402 payment not attached and sandbox not used
- Ambiguous or null input schema field may cause unexpected behavior
