Afterwren
Free API + MCP server · paid keys from $5

Retired APIs, back in one key

Clearbit-style company autocomplete, logos and company profiles, address geocoding with Census FIPS, book lookup after Goodreads, and encyclopedia search after Bing: one REST API and MCP server built on open public data. 100 free calls a day, no key; plans from $5 (one-time pack) or $19/month.

Who it's for

Developers whose code still calls an API that was switched off, and AI agents that need the same lookups.

Apps with a Clearbit company field

Point the autocomplete at /v1/companies/suggest and keep the same JSON shape.

Scripts built on the `geocoder` package

Geocode and reverse-geocode with Census FIPS codes, one HTTPS call, no SDK.

Book apps after Goodreads

Title, author, ISBN, cover and ratings from Open Library in one call.

AI agents

An MCP server with 7 tools: company lookup, logo, geocode, reverse geocode, books and encyclopedia search.

Limits, plainly

Free and rate limited so it stays fast for everyone. One lookup per call. Loop for lists; paid keys raise the per-minute rate to the plan's limit.

  • Free tier: 100 calls a day per IP, 30 a minute, no key. Paid keys from $5 (one-time pack) or $19/month (see Get an API key).
  • Every call is one lookup and counts once; failed calls are not counted. Answers are cached at the edge (company and search 6-24 hours, geocodes and logos 7 days); cached: true marks them.
  • Geocoding outside the US uses OpenStreetMap Nominatim, which allows about 1 request a second for the whole service; at busy moments a call may answer 503 busy (retry in a few seconds). US addresses use the Census Geocoder and are not affected.
  • Company profiles read only public sources: the company's homepage, public DNS and Wikidata. No personal data, no employee or contact records. Sites behind a bot wall return blocked: true with DNS and Wikidata facts only.
  • Search covers Wikipedia (English), not the whole web.

Get an API key

One API key and MCP server for the developer APIs that were switched off: Clearbit-compatible company autocomplete (same [{name, domain, logo}] shape, with working logos), company logos and public company profiles from a domain, forward and reverse geocoding with US Census FIPS (the abandoned Python geocoder package's job), Goodreads-style book search (Open Library) and Wikipedia search after the Bing Search API. Built only on open public data.

14-day money-back promise: if it doesn't work as described, email us within 14 days and we fix it or refund you in full. Refund terms.

FAQ

Is it really a drop-in for Clearbit Autocomplete?

For the suggest endpoint, yes: change the host from autocomplete.clearbit.com to afterwren.cybermaxtools.com and keep /v1/companies/suggest?query=. It answers the same JSON array of {name, domain, logo}. Results come from Wikidata, so very small private companies without a Wikidata entry are not listed.

Why not Clearbit, Brandfetch or Context.dev?

Clearbit's free Logo API ended on 1 Dec 2025 and its Autocomplete answers with logo: null since 9 Sep 2025. Brand APIs such as Context.dev charge 10 credits per brand ($19 for 750 brand lookups, 3 Oct 2026). If you need the company's name, domain, logo and basic facts, a Builder key ($5 (one-time pack) or $19/month) covers 25,000 calls a month across all 7 lookups.

What replaced the Python geocoder package?

Call /api/geocode?q= or /api/reverse?lat=&lng= with requests; the fields match geocoder's (lat, lng, latlng, address, city, state, postal, country) and US results add county, tract and block FIPS codes from the Census Geocoder.

Is there a key or a cost?

The free tier needs no key: 100 calls a day per IP. Paid keys: pay as you go: $5 for 5,000 calls that never expire (no subscription); or monthly: Builder $19/month for 25,000 calls, Pro $49/month for 100,000 calls, Team $99/month for 300,000 calls. Yearly billing gives 2 months free. Every call is one lookup. Send the key as the x-api-key header. No surprise overage charges; cancel any time.

Can AI agents use it?

Yes. Add the MCP server URL below to Claude, Cursor or any MCP client (with your key as a Bearer token for paid limits). Agents can also pay per call in USDC with x402, no account needed. Tools: company_suggest, company_logo, company_profile, geocode, reverse_geocode, book_search, encyclopedia_search.

Where does the data come from, and is it legal to use?

Only open, public sources used within their terms: US Census Geocoder (public domain), OpenStreetMap Nominatim (ODbL, attribution in every answer, rate-limited to its policy), Wikidata (CC0), Open Library, Wikipedia (CC BY-SA), each company's own public homepage and public DNS. No personal or contact data. Not affiliated with Clearbit, HubSpot, Goodreads, Amazon or Microsoft.
