SEO and AI visibility API, priced per result

Quickstart: one request, rows back

Every endpoint is an Apify Actor. Create a free Apify account, copy your API token from Settings → Integrations, and call the synchronous endpoint. It waits up to 300 seconds and returns the result rows as JSON.

curl -X POST "https://api.apify.com/v2/acts/wrenfield-data~keyword-search-volume/run-sync-get-dataset-items?maxTotalChargeUsd=1" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"keywords": ["standing desk", "walking pad"], "location": "United States"}'

import os
from apify_client import ApifyClient   # pip install apify-client

client = ApifyClient(os.environ["APIFY_TOKEN"])
run = client.actor("wrenfield-data/keyword-search-volume").call(
    run_input={"keywords": ["standing desk", "walking pad"], "location": "United States"},
    max_total_charge_usd=1,
)
for row in client.dataset(run.default_dataset_id).iterate_items():   # apify-client 1.x/2.x: run["defaultDatasetId"]
    print(row["keyword"], row.get("search_volume"))

import { ApifyClient } from 'apify-client';   // npm install apify-client

const client = new ApifyClient({ token: process.env.APIFY_TOKEN });
const run = await client.actor('wrenfield-data/keyword-search-volume').call(
    {"keywords": ["standing desk", "walking pad"], "location": "United States"},
    { maxTotalChargeUsd: 1 },
);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items.map((r) => [r.keyword, r.search_volume]));

Swap the Actor ID and input for any endpoint below. Each tool page and Store README has a prefilled input, the full output field list and the same samples. Machine-readable: OpenAPI 3.1.

Try it free: what $5 a month buys

A free Apify account includes $5 of usage every month with no card, and the API uses the same credit. With the keyword volume endpoint that is roughly 1,176 keywords a month (about $4.25 per 1,000 including the Google Ads request fee), or about 1,000 domain-metric rows (at $5 per 1,000), or roughly 100 AI visibility prompt checks (at $0.04 each). Add maxTotalChargeUsd to a call and it can never spend more than the cap.

1. Sign up (about 30 seconds) and copy the token from Settings → Integrations.
2. Paste the curl above with your token.
3. Read the rows. No sales call, no key approval, no minimum top-up. Upgrade only when the free credit runs out.

Sample response

Real output for one keyword from keyword-search-volume (United States, October 2026; monthly_searches shortened). Rows for keywords Google has no data on come back with "found": false and are not charged.

Endpoints and prices

Prices are read from the Apify API when this page is built (last build: Oct 27, 2026) and are the Free-plan tier; paid Apify plans get lower tiers automatically. Run counts are Apify's public statistics for runs by other accounts in the last 30 days. Every charge per endpoint is on its tool page.

You only pay for results

You pay mainly per result row, plus small per-request fees where the data provider charges per request (listed under each price). There is no monthly fee. Inputs with no data come back as rows marked found: false (or a status field) so your pipeline can see them, and they are not charged (the "Never charged" column). Apify's free plan includes $5 of usage every month, which is about 1,176 keyword volumes.

Spend control

• Per run: add maxTotalChargeUsd to the URL (or max_total_charge_usd / maxTotalChargeUsd in the clients). The run stops cleanly at the cap and you keep the rows already returned.
• Per account: set a monthly usage limit in Apify Console under Billing; runs stop when it is reached.
• Per call: each run's chargedEventCounts shows exactly what was billed.

Bulk, schedules and delivery

• Async: POST /v2/acts/wrenfield-data~<name>/runs returns at once; poll the run or pass a webhook for ACTOR.RUN.SUCCEEDED, then read /v2/datasets/<id>/items?format=csv (or json, xlsx).
• Schedules: Apify schedules run any endpoint daily, weekly or monthly with a saved input.
• No-code: the Apify node in n8n (templates), Make and Zapier; datasets export to Google Sheets, S3 and webhooks.

Use it from AI agents (MCP)

Every endpoint is also a typed MCP tool. Add this server URL to Claude, Cursor, VS Code or any MCP client and sign in with Apify:

https://mcp.apify.com?tools=wrenfield-data/keyword-search-volume,wrenfield-data/keyword-difficulty-checker,wrenfield-data/keyword-research-tool,wrenfield-data/competitor-keywords,wrenfield-data/domain-authority-traffic-checker,wrenfield-data/seo-toolkit,wrenfield-data/people-also-ask-scraper,wrenfield-data/google-autocomplete-keyword-expander

Ready-made suites and config: MCP suites, github.com/wrenfielddata/wrenfield-mcp, agent setup and llms.txt.

Cost compared with other SEO APIs

Competitor list prices read from their pricing pages on Oct 27, 2026. At very high keyword-volume throughput DataForSEO direct is cheaper per keyword; we say so on the DataForSEO comparison.

Stable output

We add fields but don't rename or remove documented ones. Optional fields can be null or absent, so read them with a default. Field lists live in each Store README under "Output".
