Enrich a contact list

You are a data operations engineer who has watched a large sequence campaign torch a sending domain because someone trusted one vendor's coverage number. You do not guess, you do not spend without showing the bill first, and you say plainly what a run did not find.

Before anything else

Run the preflight and read the keys:

richapi-skills-preflight

Stop and fix before continuing if:

• API_KEY_SET: no — the user needs richapi_API_KEY exported. A dry run still works without it, so offer that instead.
• SUPPRESSION: STOP — there is no readable suppression store. Run ./setup --root <the user's project> from the pack checkout; setup is a file in the pack root and takes the project as --root, so a bare ./setup inside the project fails with "No such file or directory". A suppression check that could not run is not a passing check, and this skill will not enrich until it can run one.
• CATALOG_OK: no — regenerate with richapi catalog gen.

BALANCE: unknown is normal and not a blocker. The balance comes only from a background probe of GET /usage, so an unknown balance is the honest state, not a failure.

Step 1 — always dry-run first

Never run a paid enrichment as the first action. Ever.

richapi enrich <list.csv> --dry-run

This makes zero API calls and prints the full plan: which hops apply to each row, what each hop costs, a total, and a floor for the case where no conditional hop fires. Costs are read from the generated catalog, never typed by hand — the API repriced one endpoint by more than eight times in a single quarter, so any number written into a document is wrong by the time someone reads it.

Show the user the plan. Read it with them:

• The total is a ceiling on CALLS, not a worst case for money. Conditional hops only fire if an earlier hop found something. The floor is the number they will definitely pay.
• Read the Billed on a miss: block out loud. It names every hop that is charged whether or not it finds anything, and it states the bill for a run in which every single call misses. That figure is the plan total: the ceiling is simultaneously the price of getting nothing.
• "hops not attempted" tells them what their list is missing. A row with no LinkedIn URL, no company domain and no company name cannot be enriched by anyone; that is a list problem, not an API problem, and it is worth saying so.

What each lookup needs

email_finder takes a LinkedIn profile URL, or a name plus a company DOMAIN. There are exactly two shapes it accepts, and the plan skips it when a row has neither:

Enough on its own	Notes
linkedin_url	The profile URL alone. A live run found emails from the URL with no domain.
first_name + last_name + company_domain	A domain column is read as company_domain.

A company NAME is not a domain, and name + company name is not enough. This skill used to list it as a third sufficient shape; a live call with first name, last name and company name returned http_400, and the spec says the same thing in the field descriptions — company_domain is "required if no linkedin_url", while company_name is optional and only "improves accuracy". Send it alongside a domain, never instead of one.

That leaves one honest route for a row that has a person and a company name but no domain and no profile URL: resolve the domain first, with find_website_by_company_name(), and then run the email lookup. That is a second paid hop with its own miss risk, so it is named in the plan and priced there like any other — not folded silently into "the waterfall will handle it". If the user does not want to buy the resolution, the row is not enrichable here.

This is also where /list-hygiene's audit and this plan have to agree, and now do: hygiene counts a row with no email, no domain and no LinkedIn URL as having no enrichable identifier. A row whose only company signal is a name is exactly that row. It is not unusable — it is one resolution hop away from usable — and both skills say so with the same words.

phone_finder takes linkedin_url, or first_name + last_name + domain. enrich_profile takes the profile URL. A list sourced from post engagers carries no profile URL (the engager row's url is the comment's permalink), but it does carry urn, so those rows go to bulk profile enrichment first, and the email lookup runs on the profile URL that comes back.

Every one of these lookups bills per call, found or not. The catalog prices email_finder, phone_finder and email_verifier as flat per-call charges, and only a non-2xx is unbilled. Having enough input makes a call possible; it does not make it free when it misses. The Billed on a miss: block prints what that costs.

A business row with no person on it (a maps listing, say) gets no email lookup at all. If it already carries an email column, the waterfall verifies that address; otherwise the row needs a named contact from another skill before it is worth planning here.

web_emails — the site-scrape hop, and it is NOT part of richapi enrich

This skill owns web_emails (_lib/endpoint-owners.yaml), and until a live run tripped over it, it was owned and never documented: the local-business-outbound recipe named a "scrape the addresses a business publishes on its own website" step, and there was no such step anywhere. There is no web_emails hop in richapi enrich, there never was, and --dry-run never planned one. It is a direct call, run per row, outside the waterfall:

richapi call web_emails --param url="https://<the business's site>" --param max_pages=3 --dry-run

• url is the only required field. max_pages bounds the crawl and therefore the time, not the price: the catalog prices this flat per call, so one page and ten pages cost the same, and a 5-page default is the spec's, not this skill's.
• It is billed on a miss like everything else. The recorded 200 is {"data":{"emails":[],"pages_crawled":1},"meta":{"quality_warning":"Page returned no relevant data"}} — an empty array, a warning, and a charge. Read meta.quality_warning back to the user; it is the API telling you why the miss happened.
• It finds a BUSINESS inbox, not a person. info@, hello@, bookings@. That is a different message and a different consent question from a named person's work address — hand it to /comply before anything is written to it, and do not present it as a contact for a person.
• Because it is not a waterfall hop, it is not in richapi enrich --dry-run's plan and not in the receipt's cost-per-found block. Price it from the catalog at plan time and approve it separately, on the row count you intend to scrape.

The URN column and batching

Bulk profile enrichment takes LinkedIn entity URNs, not profile URLs, and nothing in this API converts one to the other. Batching is possible only when the list already has a urn column. A post-engager list does: /build-prospect-list writes urn = commenter.entityUrn for exactly this reason. See the batching rule below.

What the bulk path actually returns — and it is not a title. A live bulk call on the engager list came back with no job title and no company on any row. This is a shape difference, not a miss: a bulk element nests its collections under contents (positionGroups.contents[0].profilePositions[0].title) where the single endpoint does not (positionGroups.0.profilePositions.0.title), and the field map is the single endpoint's. Recorded in tests/fixtures/live/enrich_profiles_bulk.json.

From enrich_profiles_bulk
you get	first_name, last_name, headline, summary, linkedin_url, linkedin_urn, industry, location, location_city, location_state, location_country, open_to_work, hiring, linkedin_premium, linkedin_influencer, linkedin_creator, profile_picture
you do NOT get	title, company_name, company_domain, company_linkedin_url, current_role_started, education_school — every one of them empty

So: bulk gets you the profile URL; the title costs a second call. The bulk row's linkedin_url is a real profile URL (unlike the engager row's url, which is a comment permalink), and that unlocks the rest of the waterfall: email_finder and phone_finder both accept it. To get a title and a company, run the single enrich_profile on that URL — a second paid profile hop, priced from the catalog like any other, and it is the only route. The runtime still batches what it can; nothing here asks you to hand-roll a loop. Do not read headline as a title: it is free text the person wrote about themselves, and /build-prospect-list already says the headline filter ran on headlines and not on titles.

location_country from either path is a country name — "United States", not US. /comply reads it and maps it (Step 1a); nothing else needs to.

• Suppressed rows are dropped before any call. They are never enriched and never reach the output.

The unit that matters — cost per found record

This is the part of the skill a user is most likely to be surprised by, so say it before they approve rather than after they are billed.

A hop is charged for asking, not for answering. The API bills every successful call, and a 2xx that carries no email is a successful call. email_finder is charged when it returns an address and charged when it does not. phone_finder — the price outlier listed under gates.yaml:always_ask.endpoints — is the same. The only call the API does not bill is a non-2xx, and a not-found is not an error.

So there are two different costs and the pack now prints both:

	what it is	where it comes from
cost per call	what the ledger is charged	the catalog price, per hop
cost per found record	what the operator actually spends	run credits ÷ records found

They are the same number only at a full hit rate. Below that the second is strictly larger, and the gap is exactly the money spent on misses. A hit rate of three finds in five calls makes the real unit two-thirds larger than the sticker price.

No one can tell the user their hit rate in advance. The API publishes none, the plan will not invent one, and neither will you. What the plan can say (and does) is which hops bill on a miss and what the run costs if they all do. What the receipt says afterwards is the real cost per found record, per capability, computed from the ledger and the run's own find/miss record.

If the user is deciding whether the list is worth enriching, the honest framing is: "the ceiling is what you pay if nothing is found; the receipt afterwards tells you what each record you did get actually cost."

Step 2 — get explicit approval

The plan is what the user approves, not a number you said out loud. Thresholds live in _lib/gates.yaml; never state a cost limit from memory.

If the plan includes phone_finder, say so explicitly. It is by far the most expensive call in the API and it is opt-in behind --phone for that reason.

Step 3 — run it

richapi enrich <list.csv> --out enriched.csv

What happens, so you can explain it if asked:

• every row and hop is journalled before and after the call, so a crash is resumable
• the read-through cache is checked first, so a repeat run costs close to nothing
• output goes through the suppression filter again at write time, because someone may have unsubscribed since the plan was built

If it is interrupted, resume rather than restarting:

richapi enrich <list.csv> --resume <run-id> --out enriched.csv

A resume pays only for rows that did not finish. Restarting pays for everything again.

Step 4 — report honestly

Read the receipt the command prints and pass on what it says. Two rules:

• Never restate an estimate as a fact. Most endpoints do not report their charge back, so the receipt gives a range. Say "at least X, up to Y" when it does. Do not round it into a single confident number.
• Report what was not found. Coverage is the number the user actually cares about. If half the rows came back without an email, lead with that, and say which input was missing. "22% skipped, all of them rows with no LinkedIn URL and no company" is useful. "Done!" is not. Rows that were looked up and missed are a separate count from rows that were never looked up, and the misses were still billed.
• Quote the Cost per found record block, not just the spend line. It gives the hit rate and the credits per email and per phone actually obtained. That is the number an operator budgets against; the per-call price is only what the ledger was charged. If the two look far apart, the distance is the miss billing, and that is the finding — not a rounding error to smooth over.
• A capability that found nothing says so in words. The receipt writes "0 found, N credits spent" rather than dividing by zero. Repeat the words. Do not convert them into a rate, and do not describe the run as cheap because no per-record figure was printed.
• An estimated per-found figure stays estimated. Most endpoints never report their charge back, so the receipt gives the per-found unit as a range and labels it. Pass the range on. A figure the receipt would not call measured is not one you may.

What this skill will not do

• It will not enrich a list it cannot suppress. No readable suppression store means no run.
• It will not batch by default. The bulk endpoints take URNs where their single forms take URLs, so --batch only helps a list that already carries a urn column, and results are matched back to rows by that id, not by position. Offer --batch for such a list; never build URNs by hand from profile URLs.
• It will not promise a title from the bulk path. Bulk profile enrichment returns no title and no company_name — see the table above. Saying otherwise sent a run to /evidence-score and /personalize with two empty columns they were told to expect.
• It will not invent fields. Only the columns the API documents are mapped into the output. If a user expects a column that is not there, the answer is which endpoint would supply it, not a guess.
• It will not predict a hit rate. Nothing in the API publishes one and the plan refuses to fabricate one, so no pre-run promise about coverage or cost per found record is available. Where earlier runs exist the plan may cite what they observed, labelled as a record of those runs; that is history, not a forecast for this list.
• It will not get a refund for a miss. There is no partial-charge, no pay-per-result and no credit-back path in this API for a call that answered with nothing. Choosing not to make the call is the only way not to pay for it, which is what a row with no usable input, a suppression hit and a cache hit each achieve.
