Strale Port Check
x402
Strale Port Check is a paid API for AI agents from api.strale.io, paid per call via x402, $0.054/call, status unknown (last checked 2026-09-14).
Check whether specified TCP ports are open or reachable on a given host via HTTP probe

How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns the reachability status for each requested port on the specified host (open/closed/timeout), along with a cryptographically hashed audit record providing tamper-evident proof of the check result.
Example use cases
Firewall audit before deployment
“Before I deploy, can you check if ports 80, 443, and 8080 are open on staging.myapp.io with a 5000ms timeout? I need to know which ones are reachable.”
Database connectivity verification
“Is port 5432 accessible on db.internal.example.com? Set the timeout to 2000ms — I'm trying to figure out if our Postgres server is reachable from outside.”
SSH access health check
“Can you verify whether port 22 is open on my VPS at 203.0.113.45? I'm locked out and want to know if the SSH service is actually listening.”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/port-checkWhen to prefer
Choose this endpoint when you need an auditable, tamper-evident record of port reachability checks — particularly in compliance, security audit, or infrastructure verification workflows where a cryptographic proof of the check is required. Prefer over simple ping tools when you need multi-port probing with a documented audit trail and micropayment-based access without API key management.
Side effects
- Host does not resolve (DNS failure) — returns error with unresolvable hostname
- All ports timeout due to aggressive firewall — returns timeout status per port
- Invalid port numbers provided — schema validation error
- Missing required 'host' query parameter — 400 bad request
- Network unreachable from probe origin — connectivity error returned
