Resolution API: pure usage-based, no minimums
Half the visitors you pay to acquire show up as "Unknown." Resolve them to verified people with post-cookie IDs attached, then score that person against a 52,000+ topic taxonomy with a second call, returning the topics they're active on. Pay only for records returned. No minimums, no setup fees, no annual prepay.

Zero risk by design
No floor to clear, no setup fee to amortize. Your bill is the resolutions you ran, and your rate falls automatically as volume grows.
Start with one campaign’s traffic or one landing page. There is no monthly floor and no platform fee. If you resolve nothing, you pay nothing.
Accept the usage terms, verify your email, and send your first call the same day. The only line item on your invoice is usage.
Each monthly volume band bills at its own rate. Once you cross into a cheaper band, every resolution above that boundary bills at the lower rate. Band counts reset monthly.
For performance teams
Every resolved visitor moves budget from spray-and-pray to a person you can name, score, suppress, and activate. All deterministic, no modeled guesswork.
Browser restrictions on third-party cookies have shrunk remarketing pools. Our first-party pixel cookie resolves to a verified hashed email and a full person record, so the traffic you already paid to acquire stays targetable instead of going dark. 50%+ of US traffic, resolved deterministically.
Any resolved person can be scored against a 52,000+ topic taxonomy through the intent endpoint, returning the topics they're active on. Bid up the in-market segment, suppress existing customers and low-intent traffic, and route high-intent visitors to sales while they are still on the site.
Resolved emails generate UID2 tokens deterministically, 4.0B of them, alongside 1.4B mobile ad IDs and 280M CTV device IDs. Activate first-party audiences on The Trade Desk and DelivrDSP, or export UID2 match keys for any other platform, without a third-party cookie in the chain.
Reverse-IP maps visitor traffic to 103M company records with firmographics and technographics. Build ABM target lists from real site activity, and stop bidding on traffic from accounts you would never sell to.
New on your API key
Resolution tells you who landed. Off-domain intent tells you who is in-market across the open web, scored per person, before they ever hit your site. The same API key now opens our off-domain person-based intent and audience-configuration endpoints, so you can bid on real demand instead of waiting for the visit.
Send a resolved person or hashed email and get back the topics they're active on from a 52,000+ topic taxonomy. Each matched topic returns a high, medium or low tier and a 1–99 strength score relative to that person’s own recent activity, not pooled at the account. Signals are distilled from ~1 trillion daily impressions across publisher co-ops, the bid-stream, and content consumption, then resolved deterministically to the person.
Configure an audience in one call: pick intent topics, score thresholds, firmographics, and recency. Every member resolves deterministically and the audience rebuilds daily. Export it to S3, email, Slack, HubSpot, Salesforce or DelivrDSP, or export match keys (HEM, UID2, MAID) for any other platform.
Pull the full 52,000+ topic taxonomy programmatically, or request a custom topic through the API.
Where this connects
Off-domain intent is person-level and resolved deterministically, no account-level inference, no device fingerprinting. Resolved records include the person’s LinkedIn profile URL where we hold one.
Already paying another vendor?
You already split-test creative, landing pages, and bid strategies. Test identity the same way. Delivr.ai is pure usage-based with no minimum, so you can run it beside your current identity or intent vendor on the same traffic and let the match rates argue.
Why deterministic
When the budget review asks why spend moved to this audience, "the vendor’s model scored it highly" doesn’t survive the meeting. A verified email match does.

“We stopped telling sales an account was in-market and started telling them which person to call. Delivr.ai gave us the identity layer that made every other tool in our stack useful.”

Vendor Consolidation
“We had six different vendors that didn't talk to each other. Delivr.ai replaced all of them with a single identity layer that every downstream system could consume. Implementation took 3 weeks.”
How it works
No SDK lock-in, no heavy onboarding. Authenticate, send an identifier, get a verified profile back.
Sign up with your work email, accept the usage-based terms online, and verify your email to activate your account. No minimums, no annual prepay.
GET a plain-text email, a SHA-256 or MD5 hash, or a LinkedIn profile URL through the lookup endpoint. One call, JSON out.
We return the verified person, company, or household, deterministically, with contact and firmographic data. Intent scores come from a separate call to POST /api/v1/intent/lookup, which returns the topics that person is active on from a 52K+ topic taxonomy.
Average implementation
A typical rollout. Most teams resolve their first profile on day one. The rest is validating against your own traffic before you flip to production.
Create your account, accept the usage-based terms online, and build on a free dev key against sample data. No minimums, no setup fees.
Wire the lookup endpoint into your CRM or warehouse. One endpoint, predictable JSON.
Plumb the resolved profile and intent topics into your destinations and workflows.
Switch to a production key, run a sample of your real traffic, and confirm match rate and data quality. You pay only for the records returned.
Review results with our team and size your production volume. Per-resolution pricing drops as you scale.
Ramp to full production volume. Your bill is your usage, nothing more.
Two weeks is the average. Lighter integrations go live faster.
Documentation
Auth, endpoints, identifier types, response schemas, rate limits, and metering, with copy-paste examples. Your engineers have what they need before the first call.

Gartner measured a 59% negative impact on buying group consensus from content tailored to individuals.

Questions performance teams ask
Building costs nothing: a free dev key runs against sample data, preview endpoints return up to 25 records free, and a dry run shows the exact billable count before a live call. On a production key you pay only for records returned, with no monthly minimum, setup fee, or seat license, so judging the match rate on one campaign’s traffic costs exactly what it resolves.
Delivr.ai resolves 50%+ of US web traffic to verified people. Because pricing is usage-based with no minimum, validating that number on your own traffic costs exactly the resolutions you run during the test.
Pure usage: you pay per record returned, misses are free, and graduated band rates that fall as monthly volume grows. The units in each band bill at that band’s rate, so crossing into a cheaper band lowers the rate for the units above the boundary, not the whole month. No floor, no annual prepay.
No. Delivr.ai never uses device, browser, or canvas fingerprinting and never models matches probabilistically. Every resolution is a deterministic match against a verified hashed email (HEM). If there is no deterministic match, the API says so.
Send a plain-text email, a SHA-256 or MD5 hash, or a LinkedIn profile URL. Plain-text emails are normalized and hashed server-side, and the public lookup endpoint returns deterministic person and company fields when there is a match.
Resolution operates on hashed identifiers, and matching is deterministic against verified data, no fingerprinting, no inference. Delivr.ai supports data subject requests (access and deletion) and honors opt-outs across the graph.
Get a key, point a slice of traffic at the endpoint, and see your own match rate. You pay only for what you resolve. No minimums, no setup fees, no annual prepay.
