Upstream APIs in. Computed answers out.

Pay-per-call APIs and MCP tools for AI agents.

Exepal turns model, search and public data into single-purpose tools that agents and people pay for per call, from $0.001. One question, one price, one JSON answer. Pay in USDC with x402, through MCP, or by card on Apify. No accounts, no API keys. The cheap tools include 20 free calls a day, no wallet needed. Get a free key for your own allowance.

MCP server:https://api.exepal.com/mcpSetup guide
For autonomous agents

You can't sign up. You can pay.

Read /llms.txt or /tools.json, POST to an endpoint, answer the 402 with USDC on Base, get JSON back. No account, no API key, no human in the loop.

For developers

One POST, one price, one JSON shape.

Twelve tools behind api.exepal.com, five of them on the Apify Store too. We own the prompts, the parsing, the scoring and the caching; you get a stable schema and a per-call price you can put in a spreadsheet.

For growth and marketing teams

Answers to the questions AI just made urgent.

Does ChatGPT recommend you or your competitor? Is that creator's audience real? Will this ad hook in the first two seconds? Ask in plain words from Claude or ChatGPT, or run a report on Apify with a card.

For partners and investors

Agents are becoming customers.

Software is starting to buy software, one call at a time. Exepal sells those buyers computed answers, over card and stablecoin rails, from one shared engine, with a markup built into every call.

Follow one call

From a question to a paid answer in six hops.

The same path runs whether the caller is an agent with a wallet, a script on Apify, or a person typing into Claude.

  1. DiscoverThe agent reads /llms.txt or /tools.json and finds a tool whose input it can fill.
  2. AskIt POSTs { brand, category, competitors } to api.exepal.com/v1/ai-visibility.
  3. QuoteThe API answers 402 Payment Required with the price, the network and the receiving address.
  4. PayThe client signs a USDC payment and retries. A facilitator settles it on Base. (On Apify, the same step is a per-event charge to a card.)
  5. ComputeThe engine fans out to ChatGPT, Claude, Gemini and Perplexity, parses every answer, scores it, and caches it for 24 hours.
  6. AnswerOne JSON object comes back with a stable shape: score, share of voice, missed prompts, cited domains, next steps.

What each tool answers. Inputs and outputs. Endpoints and behaviour. The question each tool answers. Where each tool sits in a budget.

The same list lives at /tools.json for agents and /llms.txt for language models. Status and prices on this page are read from that file.

Social profile lookup

POST /v1/social/…
Live

One public Instagram, TikTok or YouTube profile: followers, bio, verified, engagement rate, average views, how often they post and their recent posts. Instagram adds follower history where we track the account.

in handle | profile URL
out followers, bio, metrics{engagementRate, avgViews, postsPerWeek}, recentPosts[], history[], growth30d

Served from Exepal's creator index or a 72-hour cache when fresh, otherwise fetched live through public scraper Actors. Private or missing profiles return 400 and cost nothing. x402 and MCP.

Instagram and TikTok scrapers are the most-used tools on Apify after Google Maps; this is the same data as one paid call, no account.

$0.01 Instagram · $0.02 TikTok, YouTubeDetails ·

YouTube transcript

POST /v1/youtube/transcript
Live

The words of any YouTube video with captions, in the language you ask for, plus its title, channel, length, views, description and chapters.

in video URL | id, lang?
out text, segments[{start, dur, text}], chapters[], title, channel, durationSeconds, views, availableLanguages[]

Read straight from YouTube's caption tracks, manual captions preferred over auto-generated. Cached 7 days. Videos without a transcript return 400 and cost nothing. x402 and MCP.

Transcript APIs sell plans and credits; this is $0.002 a video with no signup and no charge for a miss.

Local business leads

POST /v1/leads
Live

Businesses from Google Maps for any search and place, each with address, phone, website, rating and reviews, plus the emails, phones and social profiles on its own website, emails already checked.

in query, location, limit?
out leads[{name, phone, website, rating, contacts{emails[{deliverable}], phones[], socials{}}}], summary

A Google Maps scraper Actor for the listings, then each website's home and contact page read directly and every email run through email check. Cached 7 days. x402 and MCP.

Google Maps scraping is the single most-used Actor on Apify; leads here arrive with contacts and checked emails in one call.

Page reader

POST /v1/read
Live

Give an agent any public URL and get the page back as clean markdown: title, author, date, body and links, without the navigation, cookie banners and scripts.

in url, format?, maxChars?
out content, title, description, author?, publishedAt?, links[], wordCount

Direct fetch, main-content detection, HTML to markdown, metadata from meta, Open Graph and JSON-LD. Static HTML only. Batch endpoint for ten. x402 and MCP only.

The most-called category on x402, priced at half of the usual $0.01 with no upstream cost at all.

$0.005 / page · $0.03 per 10Details ·

Domain intel

POST /v1/domain
Live

Before you trust a domain: who registered it and when, whether it really sends mail, how well its email is protected, where it's hosted and what it runs on.

in domain
out dns, email{grade}, registration{registrar, createdAt, expiresAt}, web{tech[]}, hosting, flags[], summary

DNS over HTTPS, RDAP for registration, a probe of the site for headers and tech fingerprints, risk flags computed from all three. Cached 6h. x402 and MCP only.

Fraud, sales and security agents all ask this question before acting; WHOIS vendors sell it on $99-a-month plans.

$0.005 / domainDetails ·

Email check

POST /v1/email
Live

Before an agent writes to an address: is it well-formed, does the domain take mail, is it disposable or a role inbox, is it a typo of gmail.com, and how likely is it to deliver.

in email | emails[]
out deliverable, score, normalized, mx, disposable, role, suggestion, domainSecurity{grade}, flags[]

Syntax, MX/null-MX/A-fallback, SPF and DMARC over DNS-over-HTTPS, a 214k-domain disposable list refreshed daily, provider typo distance. No SMTP probe. Batch of ten. x402 and MCP only.

Email verification APIs charge $0.004–0.01 per address on prepaid plans; this is $0.002 per call with no plan and no upstream cost.

$0.002 / address · $0.015 per 10Details ·

South Asia utility pack

POST /v1/south-asia/…
Live

The Nepali and Indian details a model guesses wrong: Bikram Sambat dates, amounts in lakh and crore and in Nepali words, phone numbers, GSTIN, PAN, Aadhaar and IFSC checks, and the official NPR exchange rate for any day.

in date | value | phone | id | currency
out exact conversion, validity, operator/state/bank, Devanagari forms, NRB buy/sell rates

Five endpoints: /date, /number, /phone, /id, /forex. Pure code for four: a cross-checked BS calendar table (1970–2090), lakh/crore wording, operator prefixes, GSTIN mod-36 and Aadhaar Verhoeff checksums. Forex reads Nepal Rastra Bank's published table, cached. x402 and MCP only.

Nobody sells this per call. It is the first piece of the South Asia data layer, priced so agents never think about it.

$0.001 / callDetails ·

AI brand visibility

POST /v1/ai-visibility
Live

Do ChatGPT, Claude, Gemini and Perplexity recommend you, or your competitor? See share of voice, the prompts you're missing from and the sources they cite.

in brand, category, competitors?, domain?, market?
out score, engines[], shareOfVoice[], missedPrompts[], topCitedDomains[], recommendations[]

Four engines queried in parallel without naming the brand in the prompt, mentions parsed and ranked, cached 24h. Tiers: /quick, default, /deep. Apify: exepal/ai-brand-visibility.

The new SEO question. Every brand will ask it, repeatedly, and very few can answer it per call without a subscription.

Creator vetting

POST /v1/creator-vetting
Live

Before you pay a creator: fake-follower risk, real engagement quality, posting consistency and a fair estimated UGC rate.

in platform (instagram|tiktok|youtube), handle, profile?
out fakeFollowerRisk, engagementQuality, consistency, redFlags[], ugcRate

Pulls public profile stats through scraper Actors, or skips the upstream entirely when you pass your own numbers. Scoring is deterministic. Apify: exepal/creator-vetting.

Creator budgets are large and mostly unvetted. A twenty-cent check sits in front of every deal.

$0.20 / profileDetails ·

Company enrichment

POST /v1/company-enrich
Live

Turn a list of domains into clean company profiles: what they do, size, socials, contacts and tech stack, ready for outreach.

in domain | domains[]
out name, description, industry, size, hq, socials, contacts, techStack[], confidence

Reads the site itself (home, about, pricing, contact), fingerprints the stack, and uses a model only to tidy the summary. Batch endpoint for ten. Apify: exepal/company-enrich.

The first input every sales agent needs, priced like a utility rather than a seat licence.

$0.10 / company · $0.80 per 10Details ·

Ad creative score

POST /v1/ad-creative-score
Live

Score a UGC or paid-social script before you spend on it: hook, clarity, call to action, platform fit, pacing and credibility, with rewrites.

in creative { platform, objective, product, script?, caption?, durationSec? }
out scores{6}, rewrites[], riskFlag

Rule checks first, then a model judge for the parts rules can't see. Batch endpoint for ten. Apify: exepal/ad-creative-score.

Sits right before ad spend, where a cheap check prevents an expensive mistake.

$0.25 / creative · $2 per 10Details ·

SERP + AI answer monitor

POST /v1/serp-ai-monitor
Live

For each keyword: your Google rank, whether the AI Overview cites you, and whether AI assistants name you. Diffed against your last run.

in domain, keywords[], brand?, country?, previousSnapshot?
out per keyword: rank, aiOverviewCited, aiMentions, diff

Google results via a search API, AI answers from the model engines, snapshot in and diff out so you can schedule it. Apify: exepal/serp-ai-monitor.

Recurring by nature: a monitor runs every week, so the revenue does too.

$0.70 / 10 keywords · $2.50 deepDetails ·
Three rails, same answer

Pay the way your caller can.

Same tools, same inputs, same JSON. Only the payment differs.

Card, through Apify

  .actor("exepal/ai-brand-visibility")
  .call({ brand: "Notion",
          category: "note-taking app" });

USDC, through x402

for agents with wallets · stablecoin

Call api.exepal.com directly. The first response is a 402 with the price; an x402-capable client pays and retries. No keys, no signup.

POST https://api.exepal.com/v1/ai-visibility
→ 402  price $3.00  network base
→ 200  { "score": 41, ... }

From Claude, ChatGPT or Cursor

for people in an assistant · MCP

Add api.exepal.com/mcp to your client and ask in plain language; an x402-capable client pays per call in USDC. Or add Apify's MCP server and pay from your Apify balance by card.

Why this exists

A thesis on the agent economy, in four parts.

Data used to be sold to people by the seat. The next buyers are programs that decide for themselves what they need and pay for exactly that.

01 · demand

Agents can't sign up, but they can pay.

An agent mid-task can't fill a sales form or wait for an API key. It can read a price and settle it. Per-call payment over x402, or a metered card through Apify, is the shape of commerce that software buyers can actually use.

02 · product

Single-purpose beats platform.

Each tool answers one question with one stable JSON shape. That makes it easy for an agent to choose, easy for a developer to trust, and easy for a marketer to understand. No dashboard to learn.

03 · economics

Margin is designed in, call by call.

Prices are set in events, not tied to one vendor's rate card, and target several times the upstream cost. Every upstream answer is cached for 24 hours, so a repeated question costs almost nothing to serve.

04 · resilience

Two rails, many sources, one engine.

Fiat through Apify and stablecoin through x402 run on the same code, operated by Socialji LLC. Tools draw on more than one upstream where possible, so no single provider can switch the business off.

Questions

Frequently asked questions.

What is Exepal?

Exepal sells single-purpose data and analysis tools as paid API calls. Each tool answers one question with one JSON shape and one price, from $0.001 a call. It's built for AI agents and the developers who build them.

Do I need an account or an API key?

No. On api.exepal.com the price is quoted in an HTTP 402 response and paid per call in USDC on Base with the x402 protocol. If you'd rather pay by card, the five analysis tools are also Actors on the Apify Store.

What is x402?

x402 is an open protocol that uses the HTTP 402 Payment Required status code so a program can pay for a request on the spot. The server replies with a price, the client signs a stablecoin payment and retries, and gets the answer. No signup, no invoice.

How do I use Exepal from Claude, Cursor or ChatGPT?

Add https://api.exepal.com/mcp as a remote MCP server. Every tool appears with its price, and an x402-capable client pays per call in USDC. Or add Apify's MCP server (mcp.apify.com) and pay from your Apify balance by card.

Am I charged if a call fails?

No. Payment only settles when the tool returns an answer. A page that can't be fetched or an upstream outage returns an error and costs nothing.

Who runs Exepal?

Exepal is operated by Socialji LLC, a Delaware company. Write to contact@laxmankafle.com.
