Verified domains by claimed DR, deduplicated across every supplier we buy from. Every domain that failed verification is excluded.
Less admin. Better decisions.
Spend less time managing link purchases.
Finding a placement is only part of the work. You still have to compare offers, check the publisher, place the order, send content, and track delivery. Placement API brings those steps into one workflow, so you spend more time deciding where to invest and less time administering each purchase.
Turn a brief into a priced plan.
Specify your criteria and budget. Get a plan with the cheapest available seller for each selected domain, suspect inventory excluded by default, and prices held for 4 hours.
Manage purchases in one place.
Order placements, send your content, and track delivery through the same integration. One balance and one invoice across suppliers.
From brief to delivery
One workflow. You make the call.
“Find finance placements for this page, within my budget. Compare prices and show me a plan before buying.”

Relevance first.
Match your campaign to relevant publishers across every supplier, then compare prices for the placements you select.
Discovery reads topic, audience and composition, not just a rating.
Same placement.
Better price.
The same domain can appear in several supplier catalogues at different prices. Placement API puts those offers side by side and routes to the lowest available price for the placement you need.
Routing happens after quality selection, never instead of it.
Live listings, cycling. Sites and suppliers are both unnamed. Which publisher is hollow, and which supplier is expensive on it, is the part we do the work to know.
Your workflow.
Connected.
Approve a plan, place the order, then follow delivery without leaving the API. Status flows back to the tools you already use.
The same calls whether a person or an agent makes them.

More from your budget

Look beyond the score
Choose publishers with more than a rating to go on.
A high domain rating is only one signal. Before you commit budget, you need to know what supports it.
Placement API checks domains against five screening criteria, using search traffic, ranking keywords, backlink signals, and the public web graph. Domains that fail are flagged in every response and excluded from generated plans by default, so screening becomes part of purchasing rather than a step before it.
See how we screen domains →Automation with boundaries
Give your agent purchasing power. Keep the controls.
Set clear boundaries over what can be spent and when. The platform enforces them.
Connect your agent →Start with search access.
Read-only keys let your agent explore inventory and prepare plans. Ordering requires separate permission.
Set spending limits.
Per-order and daily caps are enforced in the same statement that charges the purchase, not asked for in a prompt.
Keep the price you approved.
Quoted prices are held for 4 hours, giving you time to review a plan before purchasing.
No duplicate charges on retries.
Required idempotency keys prevent a retried order request from becoming a second purchase.
After you buy
Visibility doesn’t end at checkout.
Track whether an order needs content, is in progress, or has been delivered. Cancel for a full refund before your order is sent to the supplier. Refunds cover undelivered orders under the delivery policy, and delivered links are checked for a year for presence, dofollow status, and the agreed anchor text.
