How to get an API key

BetterContact uses API key. The steps below follow BetterContact's own docs.

Create a BetterContact account. API access starts on the Starter plan.
app.bettercontact.rocks/api_requests; regenerate or deactivate there; keys are per user, credits pooled per organisation
Send it with every request: header X-API-Key (NOT Authorization: Bearer, which returns 401); enrich_profile endpoints also accept api_key in the body.

Make a first call: Submit up to 100 leads for waterfall email and/or mobile enrichment. Keep the key in an environment variable, never in the command.

curl -X POST "https://app.bettercontact.rocks/api/v2/async" \
  -H "Authorization: Bearer $BETTERCONTACT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'

Strengths and limits

Where it fits

One-bill access to 20+ email/phone providers without holding their keys
Mobile numbers with phone verification (Trestle, IPQS, internal) and Connect Intelligence scoring on Pro
Catch-all email verification (catch_all_safe / catch_all_not_safe) on Pro
Batch enrichment of up to 100 leads per call with webhook delivery
Search-and-enrich in one call: Lead Finder with enrich_email_address / enrich_phone_number

Where it falls short

Stacking inside another waterfall (it already calls Prospeo, Hunter, Apollo, PDL and others)
Phone enrichment on Starter without the phone add-on (402 rejected)
Verifying webhook origin cryptographically: webhooks carry no signature
Company Finder pipelines that need push delivery: Company Finder has no webhook

Worth knowing

Branch on body.status, never on HTTP code: GET endpoints answer 202 with an empty body while running; only status 'terminated' guarantees results
Submissions are not idempotent: retrying a POST that actually succeeded enriches and charges twice; check GET /account before resubmitting after a timeout
on_hold (balance hit zero mid-flight) resumes by itself after a top-up, so do not resubmit; but a Company Finder on_hold never resumes and must be resubmitted
402 means either out of credits or feature not on plan (phone add-on, catch-all add-on); read message to tell them apart
Unknown request id: 406 on enrichment, 404 on Lead/Company Finder

8 moreShow fewer

Filter values not in the Taxonomies list (industries, technologies, seniority, departments, functions, revenue, funding rounds, countries) silently match nothing; Company Finder silently ignores exclude and unknown keys; company domain is case-sensitive
A Lead Finder search for one domain with limit 1 is rejected with 422; use /enrich_profile/company
credits_left / credits_consumed on Company Finder are decimal strings ('998.5')
Per-lead webhook custom_fields come back as an array of {name, value, position}, not the object you sent
Pricing page says 'No charge for catch-alls whatsoever', but the credits doc says catch-alls ARE charged when verify_catch_all is off, and catch-all verification is not on Starter
Rate limits rose from 60/min (our April 2026 copy) to 100 or 200/min by plan
Credit roll-over: the pricing page plan cards say 'capped at your subscribed credit amount' but the same page's example and FAQ say capped at 2x (5,000-credit plan holds max 10,000). Annual plans extend roll-over to 12 months. Source: bettercontact.rocks/pricing (verified 2026-10-25)
Free signup credits disagree in the vendor's own copy: 50 (pricing page, app login page) vs 100 (app signup page). Source: bettercontact.rocks/pricing; app.bettercontact.rocks/users/sign_up (verified 2026-10-25)

Our take

We left BetterContact out of an enrichment waterfall we built for a B2B data company: it is itself a multi-provider waterfall, so it overlapped the providers we already called, and the orchestration platform we used could run it only on the platform's own credits.

Who should use it

Use BetterContact for: One-bill access to 20+ email/phone providers without holding their keys
Look elsewhere for: Stacking inside another waterfall (it already calls Prospeo, Hunter, Apollo, PDL and others)

Before you build

Four things to settle first, each read off BetterContact's own pages.

Confirm the API is on your planAPI access starts on the Starter plan. Free tier: 50 free credits on signup, no credit card (pricing page and app login page).

Design around the rate limitPer API key, across all endpoints together.

All 9 endpointsFor developers: method, path, what it does and what it costs.

Base URL: app.bettercontact.rocks/api/v2

Bulk and async: Up to 100 leads per POST /async; Lead Finder and Company Finder up to 200 results per page

Webhooks: Yes for /async and Lead Finder (not Company Finder). Sent once when the request reaches terminated; body identical to the GET payload; retried up to 5 attempts (10s, 2min, 3min, 4min). No signature or auth header: treat URL as secret and confirm via GET /async/{id}. Per-lead contact_webhook (push_contact_individually) is never retried.
