Not comparable. This product publishes no rate for this kind of work.

- The replacement page does not state a free allowance.
Product scope and returned result
The product represented by this record is the legacy Bing Search API family, not Microsoft’s current agent-grounding tool. Microsoft decommissioned every Bing Search API instance on August 11, 2025 and closed new signups. The current first-party replacement, Grounding with Bing Search, lets an Azure AI Foundry agent or supported Web Knowledge Source consult public web data while producing a model response. It returns summarized, grounded material through that agent workflow, with publisher citations and a link to the Bing query. Microsoft says the grounding output is not directly accessible for use in an arbitrary application, so it is not a drop-in raw-results API. (retirement notice and Grounding with Bing, retrieved 2026-07-26).
That distinction is the useful answer for a buyer comparing neighboring search APIs. A workload that needs a JSON array of reusable result records needs another product. A workload already built around Azure AI Foundry agents may be able to use Grounding with Bing, but its output and display obligations belong to the agent response path. (Grounding with Bing, retrieved 2026-07-26).
Meter and contract path
The retired API has no current billable meter because there is no current purchase path. The replacement meters a grounding transaction when summarized Bing results are returned. Microsoft publishes $14 per 1,000 transactions, with limits of 150 transactions per second and one million transactions per day. The Search and Custom Search grounding plans use the same published transaction price. (Grounding with Bing, retrieved 2026-07-26).
There is no quote request, minimum commitment, or trial for the retired Bing Search API because it cannot be bought. For the replacement, Microsoft provides direct Azure portal links to create a Grounding with Bing Search or Grounding with Bing Custom Search resource. The reviewed page does not state a free allowance or a minimum purchase. A buyer needs an Azure account and must choose the supported Foundry or Web Knowledge Source integration. The application must also be able to show the required citations and Bing query link to end users. (Grounding with Bing, retrieved 2026-07-26).
Price status and why this record has no published plan price
The absence is a lifecycle fact, not withheld enterprise pricing. The legacy product is retired. Microsoft’s $14 transaction rate belongs to a materially different, agent-bound replacement, so recording it as a monthly Bing Search API plan would misstate both the contract and the output. Historical legacy prices are not useful purchase guidance. (retirement notice and Grounding with Bing, retrieved 2026-07-26).
Priced alternatives
- Tavily can provide a current search API on its Project plan at $30 per month. (Tavily API credits, retrieved 2026-07-26).
- Olostep combines web search with page retrieval on its Starter plan at $9 per month. (Olostep, retrieved 2026-07-26).
- Firecrawl includes search and page retrieval on its Hobby plan at $16 per month when billed annually, or $19 month to month. (Firecrawl pricing, retrieved 2026-07-26).
These alternatives publish an entry plan and can serve a raw-search or search-plus-content job. They should not be treated as protocol-compatible replacements without checking their response schemas and usage terms. (Tavily, Olostep, and Firecrawl, retrieved 2026-07-26).
