GET /tools/spf/{domain}

Count the DNS lookups in an SPF record against the limit of 10.

No API key. 10 checks a minute from one network. include, a, mx, ptr, exists and redirect count toward 10. ip4, ip6 and all do not. A lookup that answers with nothing counts toward the void limit of 2. Stores nothing.

Request

The same call in curl, Node and Python. A path id in the sample is a placeholder.

curl

curl -sS -X GET https://api.agentisend.com/tools/spf/example \
  -H "Authorization: Bearer $AGENTISEND_API_KEY"

Node

import { AgentiSend } from 'agentisend';

const client = new AgentiSend(process.env.AGENTISEND_API_KEY);
const result = await client.request({
  method: 'GET',
  path: '/tools/spf/example',
});

Python

import json, os, urllib.request

url = 'https://api.agentisend.com/tools/spf/example'
headers = {'Authorization': 'Bearer ' + os.environ['AGENTISEND_API_KEY']}
request = urllib.request.Request(url, headers=headers, method='GET')
print(urllib.request.urlopen(request).read().decode())

Tag: meta. Generated from openapi.json; the anchor get-tools-spf-domain is the id the console's error fix links point at.

Errors

The codes this operation can answer with, and what to do about each. Every one arrives with its code, message, fix and docs_url.

  • internal_server_error (500, internal_server_error) — Unexpected error. Fix: Retry ONCE after a short pause, with the same Idempotency-Key so the retry cannot double-send. If it fails again, stop retrying and report the x-request-id from the response — that id is what identifies this exact failure in support.
  • invalid_parameter (422) — A parameter has an invalid value. Fix: Correct the named parameter and retry.
  • mailbox_provider_domain (422) — You cannot send as a mailbox provider’s domain. Fix: Add a domain you own with POST /domains, such as acme.com or mail.acme.com, and send from an address on it.
  • rate_limit_exceeded (429, rate_ceiling_exceeded, rate_limit_exceeded) — Too many requests. Fix: Back off and retry honoring the Retry-After header.
  • validation_error (400, domain_not_verified, invalid_parameter, validation_error) — Error in one or more fields. Fix: Correct the fields listed in the error details and retry the request.
