looot

Tools: search_catalog, inspect, run, runs_get, runs_list, runs_evidence, balance, top_up, catalog_overview, capability_request, media_link. Searching, inspecting, balance and run history are free.

When to Use

Use it before guessing, scraping by hand or signing up for another tool, whenever the answer lives outside this conversation:

• Find or verify a work email or phone number. Enrich a person or a company.
• Google results, keyword volume, backlinks, domain strength, and whether AI answers cite a brand.
• Social profiles and posts (LinkedIn, X, TikTok, Instagram, YouTube), ads, local businesses, jobs.
• Read a web page as markdown, search the web or the news, stock prices, transcripts, speech.

Example asks: "Use looot to find the work email of Patrick Collison at stripe.com", "Use looot to pull today's trending TikTok videos", "Use looot to check who ranks for 'best crm' in France".

Connect and sign in

looot is one MCP server at https://api.looot.ai/mcp. Sign-in is OAuth in the browser. Nobody copies a key.

Add the server to your client (in Claude Code: claude mcp add --transport http looot https://api.looot.ai/mcp). If its tools are missing or answer 401, re-authenticate the server in your client (in Claude Code, run /mcp, pick looot, choose Authenticate), then pick the organization to bill on looot.ai and click Connect.

Never ask the user to paste a token or password into the chat, and never write one into a file or URL. A bearer agent token is only for CI and headless agents, created at https://looot.ai/settings. A new workspace starts at $0 with no trial credit. After sign-in, call balance once.

The method

1. Search, in plain words, by the job and the input you have:

search_catalog {"query": "find a work email from a name and a company domain"}

2. Compare rows on works (success rate, runs, p50Ms; thin: true means fewer than 5 runs back the rate), costPerSuccessUsd (the price divided by the success rate, the number to compare) and access. Only runs_now runs immediately. needs_your_account means the user connects their own account first. coming_soon has no key yet, so skip it.
3. Read jobInputs in the answer. It lists which input names each job's endpoints accept, so you can pick the input you already have.
4. Inspect the pick for the exact inputs, price formula and the most one run can hold:

inspect {"endpointId": "icypeas-email-verify", "detail": "run"}

5. Run it with a fresh idempotencyKey for every new run. The same key replays the same run and never charges twice, so retrying after a dropped connection is safe:

run {"endpointId": "icypeas-email-verify", "input": {"email": "jane@example.com"}, "idempotencyKey": "<new unique key>"}

To let looot choose the provider, run the job instead: job:<job id> as the endpointId, with fallback. If the first provider misses or errors, looot tries the next provider of the same job inside one hold, and only attempts that ran are charged:

run {"endpointId": "job:people.email.find", "input": {"first_name": "Patrick", "last_name": "Collison", "domain": "stripe.com"}, "idempotencyKey": "<new unique key>", "fallback": {"maxAttempts": 3, "maxCostUsd": 0.1}}

fallback also takes prefer (balanced, cheapest, reliable, fastest), exclude and stopAtFirstMiss. Only lookups fall through. Anything that changes data runs once.

Never invent an endpoint id, a job id or an input name. Use ids from a search answer or the table below. Nothing fits? Rephrase, browse the free overview of categories and jobs, then call capability_request.

Common asks and the job to run

Run each as job:<id> with fallback.

The user says	Job	Input
Find the email of Jane Doe at Acme	people.email.find	name and domain, or a LinkedIn URL
Is this email real?	people.email.verify	the email
Get her phone number	people.phone.find	LinkedIn URL, or name and company
Tell me about acme.com	company.enrich	the domain
Find SaaS companies in France, 50 to 200 people	company.search	the filters
Find marketing heads at these companies	people.search	company and title
Who works at acme.com?	people.domain.search	the domain
What tech does this site use?	company.technographics	the domain
Is Acme hiring?	jobs.company	the company
What does Google show for this keyword?	google.serp.organic	keyword and country
Are we cited in Google's AI answer?	google.serp.ai-mode	the question
How strong is our domain?	backlinks.domain.summary	the domain
Read this page	web.scrape.markdown	the URL
Search the web or the news	web.search, news.search	the query
LinkedIn profile	linkedin.person.profile	the profile URL
TikTok account stats	tiktok.user.profile	the handle, no @
Transcribe a YouTube video	video.transcript.get	the video URL
Dentists in Lyon	maps.local.search	what and where
What ads is this brand running?	ads.meta.search	the brand
Amazon product price	amazon.product.get	URL or ASIN
Latest price of AAPL	stocks.quote.latest	the ticker

For anything else, search. Check input names against jobInputs, because live names win over this table. A run that answers needs_input lists the fields to add.

Money

• The balance is prepaid USD. A run first holds its estimated cost, then settles the real charge, and the rest of the hold goes back.
• Quote before you run. For a batch, multiply costPerSuccessUsd by the row count, tell the user the total and check balance.
• Before more than 100 calls in one go, tell the user the estimated total and wait for a yes.
• A refused call charges $0: bad input, needs_input, unknown_job, no_supply_for_job, route_capped, route_no_fit, and provider errors or timeouts.
• A "not found" is free unless that provider bills for it. Each attempt in route.attempts has billed, and actualCost is what was charged.
• fallback.maxCostUsd caps the whole route. A provider priced above what is left is skipped as over_cost_cap.
• Call top_up only when the user asks or a run is blocked for balance. It returns a Stripe checkoutUrl. Show it as a link and wait. Never enter card details. When they say they paid, call balance again. The live minimum is topUpLink.minimumUsd.

Read the result

Check status and error first. A tool call can succeed and still hold a run with status: "failed".

• outcome is hit, weak, miss, error, rejected, skipped or pending. weak with verdict: "guessed" is a pattern guess, so verify it before use. A miss means that provider found nothing, not that the thing does not exist.
• result is the provider's answer. normalized (some jobs) has fixed field names, such as email, status and deliverable for verification, or markdown and title for a scrape.
• servedEndpointId and servedProviderId say who answered, which differs after a fallback. Name the provider behind each fact.
• route.summary lists each attempt and what it charged. actualCost is the total.
• status: "queued" or "running": poll runs_get with the runId. Do not start a second run.
• A file result (audio, image, video, PDF) comes back through media_link as a short-lived link.

Receipts and history:

runs_evidence {"runId": "<runId>"}

runs_list {"status": "completed", "limit": 20}

Recipes

Lead list. Quote it first. For each lead, run job:people.email.find with first_name, last_name and domain, using a key like <list>-<row>-find. Then run job:people.email.verify on every address you keep. Keep valid, flag catch_all and risky. Run a few leads at a time, and report found, verified and the total actualCost.

Company brief from a domain. Run company.enrich, company.technographics, company.news and people.domain.search with {"domain": "<domain>"}. Write one short brief with the provider behind each fact.

SEO and AI visibility for a keyword. Run google.serp.organic, then search for google.serp.ai-mode, search.google-ai-overview and search.chatgpt, and look for the brand and its domain in each answer and in the sources cited. Add google.keywords.volume (priced above a results page, so quote it) and backlinks.domain.summary.

Page to markdown. Run job:web.scrape.markdown with {"url": "<url>"} and fallback. A blocked or sign-in page counts as a miss, and fallback moves to the next scraper.

Social profile. Run linkedin.person.profile or linkedin.company.profile with linkedin_url, or tiktok.user.profile and instagram.user.profile with handle. For another network, search for it.

Keep results the user will need again in a local file, a sheet or their CRM, so they never pay twice for the same data.

Errors

A run can answer HTTP 201 and still have failed. A failed run has error with code, message, whoseError (customer, provider or gateway), retryable and retryHint. For a job: refusal the exact reason is in result.code.

Code	What to do
needs_input	Add one of the fields result.needs names, then run with a new key.
no_supply_for_job	No endpoint does this job. Rephrase, pick another job, or call capability_request.
no_runnable_provider	Nothing can run for this workspace right now. Retry later or pick another job.
unknown_job	Use one of the close ids the message suggests.
invalid_input	Fix the broken email, url, domain or phone, and use a new key.
route_capped	Every provider costs more than maxCostUsd. Raise the cap after telling the user the price.
route_no_fit	Read route.skipped and add the field it says is needed.
validation_error	An argument is wrong. The message names the field. Never guess argument names.
insufficient_balance	Show topUp.checkoutUrl, wait for payment, retry with a NEW key.
top_up_amount_out_of_range	Call top_up with at least minimumUsd, or with no amount.
idempotency_conflict	That key was used with another input. New run, new key.
too_many_inflight_runs	Wait 2 seconds and retry with the same key.
forbidden	The sign-in lacks the runs:execute scope. Sign in again and allow running.

A 401 or missing tools means the sign-in expired, so connect again. Quote the requestId when the user contacts support.

Limitations

• looot reads data and calls provider APIs. It cannot post on social media, log in to sites as the user, buy things, or read private accounts and messages.
• Coverage varies. A "not found" is a normal result.
• It is not a database. Runs are kept and readable with runs_list and runs_get, but keep the data you need in your own file.
• Keep tokens out of the chat, logs and code.
