# DNS HTTPS Record Parse

> DNS HTTPS Record Parse is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Parses and validates DNS HTTPS resource record fields — service priority, target name, and service parameters — from a caller-supplied record string, returning normalized findings and a pass/advisory status.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/dns-https-record-parse
- Price: $0.001/call
- Payment: x402
- Status: unknown

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 dns-https-record-parse-99d5b426 -d '<json body>'
```

Example prompt: Parse this DNS HTTPS record string for me and tell me whether the service priority, target, and parameters are valid: 'v=HTTPS 1 . alpn="h2" ipv4hint=192.0.2.1'

## When to prefer this

Use this endpoint when you need a lightweight, deterministic, first-party parser for DNS HTTPS resource records — especially before accepting, caching, redirecting, or retrying a web response based on a caller-supplied record. Prefer it over general-purpose DNS libraries when you need a normalized JSON output with explicit pass/advisory status and no external provider dependency.

## Known failure modes

- Malformed record string returns advisory status with error details
- Record exceeding 8192 characters is rejected
- Missing or empty record field returns validation error
- Unrecognized or non-standard service parameters may yield advisory rather than pass status
- Payment failure (x402) results in request not being processed

## How this service works

DNS Https Record Parse: DNS Https Record Parse parses HTTPS service priority, target, and bounded service parameters from bounded caller-supplied values without an external provider. Call DNS Https Record Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS Https Record Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party,…

## Output

Returns versioned deterministic JSON containing normalized web evidence (extracted service priority, target, and service parameters), the computed parsing finding, and an explicit pass or advisory validation status for the supplied DNS HTTPS record string.
