The tools return a model's answer with citations, never the raw results, and data sent to them falls outside Microsoft's Data Protection Addendum and Azure's compliance boundary.\n\n## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | Microsoft (https://www.microsoft.com/bing/apis) |\n| Kind | HTTP API |\n| Category | Web search APIs (https://www.anchorterminal.com/categories/search) |\n| Transport | Streamable HTTP |\n| Endpoint | `https://{account}.services.ai.azure.com/api/projects/{project}/openai/v1/responses` |\n| Auth | OAuth · Microsoft Entra ID bearer token for the Foundry project (scope https://ai.azure.com/.default, for example through DefaultAzureCredential), with the Foundry User role to create and run agents. The bing_grounding tool also needs a Grounding with Bing resource whose key is stored in a project connection, created by someone with Contributor and Foundry Project Manager. The agent never holds the Bing key. The web_search tool needs no Bing resource or connection. |\n| Pricing | Pay per use ($14 / 1k req) · $14 per 1,000 transactions for Grounding with Bing Search and for Grounding with Bing Custom Search, counted as tool calls per run, plus the model deployment's token charges. No free tier found. An Azure subscription and a person's signup are needed first. |\n| x402 | No · No x402, MPP or L402 on the Foundry web search and Bing tools pages, the Grounding with Bing pricing page or the terms of use (checked 2026-11-06). Billing runs through the Azure subscription. |\n| Licence | Proprietary service under the customer's Microsoft agreement and the separate Grounding with Bing terms of use, which exclude it from the Microsoft Data Protection Addendum |\n| Tools exposed | 3 |\n| Packages | pypi: `azure-ai-projects`; npm: `@azure/ai-projects` |\n| Docs | https://learn.microsoft.com/en-us/azure/foundry/agents/how-to/tools/web-search |\n| llms.txt | not found |\n| Last release | 2026-11-02 |\n| Surface listed | The Grounding with Bing Search and Custom Search tools (`bing_grounding`, `bing_custom_search_preview`) and the general `web_search` tool in Foundry Agent Service, called through the project's Responses API or a toolbox MCP endpoint. Read from Microsoft Learn, the Grounding with Bing pricing page and terms of use on 6 November 2026. No Azure account was made and no call was sent |\n| Three tool types | `web_search` (WebSearchTool) adds Bing-backed search to a prompt agent or a toolbox with no Bing resource. `bing_grounding` needs a Grounding with Bing resource and a project connection. `bing_custom_search_preview` restricts grounding to domains configured in a Bing Custom Search instance, and is marked preview |\n| What comes back | A model-generated answer with `url_citation` annotations and a link to the Bing query. The Bing tools do not return their raw output. Over MCP the toolbox returns one resource item holding the answer, with citations in `_meta.annotations` |\n| Parameters | `count` (default 5, at most 50), `freshness` (Day, Week, Month or a date range), `market` (such as en-US) and `set_lang` for bing_grounding. `user_location` and `search_context_size` (low, medium, high) for web_search |\n| History | The standalone Bing Search APIs were retired on 11 August 2025, after a notice dated 16 May 2025 that named Grounding with Bing Search as the replacement |\n| Data boundary | Only the Bing query, tool parameters and the resource key are sent to Bing, outside the Azure compliance boundary and outside the Data Protection Addendum. Microsoft and the customer are independent controllers under the terms. Bing traffic uses public egress even from a network-secured project |\n| Regions | Grounding with Bing Search is listed for a subset of regions, including West Europe, Canada East, Switzerland North, East US, West US, UK South, Japan East and others on the limits page. Not every model supports the tools |\n| Display rules | The terms require showing the website URLs and the Bing search query URL, unmodified, near the output, and allow the output only in search experiences relevant to the user's query |\n| Admin control | `az feature register --name OpenAI.BlockedTools.web_search` turns web search off for every Foundry account in a subscription |\n| Capabilities | web.search, search.answer |\n| Tags | hosted, usage-priced, closed-source, enterprise, card-required, status-page, python, typescript |\n| JSON | https://www.anchorterminal.com/api/v1/tools/bing-grounding.json |\n\n## Score breakdown (methodology v0.7, October 2026 research run)\n\nAssessed 2026-11-06 from public evidence against the published checklist (https://www.anchorterminal.com/benchmark/#checklist). Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 68 | 13.6 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 68 | 11.1 |\n| Agent ergonomics | 13% | 16.2 | 61 | 9.9 |\n| Security \u0026 auth | 14% | 17.5 | 79 | 13.8 |\n| Payments \u0026 pricing | 10% | 12.5 | 20 | 2.5 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 80 | 7.0 |\n| Transparency \u0026 trust (editorial 45, provenance 87) | 7% | 8.8 | 66 | 5.8 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **63.7 → B** |\n\n### Why each score\n\n- Reliability 68 (checked 2026-11-06): Graded on the hosted lines, for the Foundry Agent Service tools agents call. Azure status page with post-incident reviews and a Foundry Agent Service component (20). The history page read on 6 November lists one review in the 90 days from 8 August that names Foundry Agent Service, intermittent failures and latency in Sweden Central from 10:03 to 15:58 UTC on 29 September 2026. It was one region and partial, and the review doesn't name Grounding with Bing, so minor only, the reading the Azure Translator listing got for the same review (20). The pricing page publishes 150 transactions a second and 1 million a day for each Grounding with Bing resource (15). The web search troubleshooting table says to answer 429 with exponential backoff and retries. No Retry-After or tool-specific overload guidance was found, and searches have no side effects (8 of 15). No SLA naming Grounding with Bing was found. The terms make it a First Party Consumption Service apart from the Online Services terms, and the Online Services SLA document wasn't opened (0). Grounding with Bing Custom Search is marked preview and Grounding with Bing Search is not, but no page read states general availability for it or for the web_search tool, and the .NET SDK is in preview (5 of 10). 20 + 20 + 15 + 8 + 0 + 5 = 68.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 68 (checked 2026-11-06): The tools are typed in the official SDKs (BingGroundingTool, BingCustomSearchPreviewTool, WebSearchTool) in Python, C#, JavaScript and Java, and the toolbox exposes web search as an MCP tool. No public OpenAPI description of the Responses tool types was confirmed from the pages read (10 of 25). Microsoft Learn serves each page as Markdown with `accept=text/markdown`, though learn.microsoft.com/llms.txt answers 404 (10). The pages say what each of four web grounding routes is for and when to choose it, when to use Custom Search instead, and not to ask the model to summarise a whole page (17 of 20). Parameters are typed with defaults and limits in prose, `count` 1 to 50 with default 5, freshness values and a date-range form, market and language formats, `search_context_size` low, medium or high (11 of 15). Examples in Python, C#, TypeScript, Java and REST with expected output, and troubleshooting tables for connection ID, authentication and 429 problems, but no error codes or bodies for the tools (10 of 15). Requests carry `api-version=v1` on the toolbox, SDK changelogs are dated and a monthly What's New page lists new articles, the latest for August 2026 (10 of 15). 10 + 10 + 17 + 11 + 10 + 10 = 68.\n- Agent ergonomics 61 (checked 2026-11-06): Read as a server-side search tool inside an agent run. The tools return a model's answer with citations rather than raw results, and `search_context_size` sets how much context web search uses. A caller can't size or inspect the result set itself, since the Bing tools never return their output. Custom Search confines grounding to chosen domains without code (18 of 25). `count`, freshness, market and language filters, and domain restriction through Custom Search. No pagination or offset (13 of 20). Troubleshooting tables give causes and fixes for connection ID, RBAC and 429 problems, but the tools document no error codes (8 of 20). Searches only read, so a retry is safe apart from the per-transaction charge. No MCP annotations are documented for the toolbox's web search tool (10 of 20). The web_search route needs only a project, a model deployment and the Foundry User role. bing_grounding also needs a paid Bing resource and a project connection. SDKs in Python, C#, JavaScript and Java (12 of 15). Prompt caching gets no hits with the Bing tools, because they add a timestamp to every request. 18 + 13 + 8 + 10 + 12 = 61.\n- Security \u0026 auth 79 (checked 2026-11-06): Callers authenticate to the Foundry project with Microsoft Entra ID tokens and RBAC roles (Foundry User to run agents, Foundry Project Manager to add connections), with just-in-time Contributor through Entra PIM for provisioning. The Bing resource key sits in a project connection and the agent never holds it. No key in a URL (28 of 30). The tools only read. Custom Search confines grounding to configured public domains, and an admin can turn web search off for a whole subscription. There is no per-agent read-only toggle to set, since the tools have no write path (15 of 20). The web search page tells developers to treat web search results as untrusted input and to keep secrets and personal data out of prompts, and the tool best practices page says the same of all tool outputs. Raw results are not passed back to the caller (10 of 15). Run steps show each tool call and the Bing query sent, and Azure's activity log covers resource changes. No per-query audit log for Bing was found (10 of 15). Microsoft runs a coordinated vulnerability disclosure policy and bounty programmes through MSRC. microsoft.com's security.txt passed its Expires date on 23 September 2026 and still carries it on 6 November, and the Azure compliance attestations are not shown to cover a service whose data leaves the compliance boundary (16 of 20). 28 + 15 + 10 + 10 + 16 = 79.\n- Payments \u0026 pricing 20 (checked 2026-11-06): No x402, MPP or L402 (0). $14 per 1,000 transactions for Grounding with Bing Search and Custom Search, published on microsoft.com without a login (20). No free tier for Grounding with Bing, and an Azure subscription needs a card, as on the Azure Translator listing (0). A person signs up for Azure, creates a Foundry project and, for bing_grounding, a Bing resource (0).\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 80 (checked 2026-11-06): Read as a closed service with official SDKs, as the other Azure listings are. The web search page was updated on 2 November 2026 and the Bing tools page on 12 October, and azure-ai-projects 2.10.0 shipped on PyPI and npm on 30 October 2026, the SDK that carries the tool types (30). azure-ai-projects released 2.6.0 (4 September), 2.6.1, 2.7.0, 2.8.0 (5 October), 2.9.0 (17 October) and 2.10.0 in the 90 days from 8 August. Their changelogs weren't read for web search changes, so they count as SDK releases (20). Microsoft Learn feedback, Microsoft Q\u0026A and the Azure SDK issue trackers, whose reply times weren't sampled (10 of 15). Current official SDKs in Python, JavaScript, .NET and Java, the .NET one in preview (15). The SDKs live in the azure-sdk monorepos and CI wasn't checked (5 of 10). 30 + 20 + 10 + 15 + 5 = 80.\n- Transparency \u0026 trust 66 (checked 2026-11-06): Closed service. The terms of use, updated November 2025, are separate from the Online Services terms and sit under the customer's Microsoft agreement (15 of 30). The docs and the terms agree that the Data Protection Addendum and the Product Terms' privacy and security terms don't apply, that Microsoft and the customer are independent controllers, and that the query and parameters leave the Azure compliance and geographic boundary. The terms defer storage and use of query data to the general Microsoft Privacy Statement and state no retention period (15 of 30). The Bing Search APIs retirement was announced on 16 May 2025 for 11 August 2025, under three months' notice, and the web search page marks the Deep Research tool deprecated with a replacement. Microsoft's lifecycle policy covers Azure services, but no deprecation terms for Grounding with Bing were found (10 of 20). Data location for Bing processing isn't stated, and no sub-processor list for it was found (5 of 20). 15 + 15 + 10 + 5 = 45.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (17 items). What it covers is at https://www.anchorterminal.com/fixes/bing-grounding.md (JSON https://www.anchorterminal.com/fixes/bing-grounding.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{\"listing\": \"bing-grounding\", \"plan\": \"read\"}`, free while the beta runs\n\n### What we couldn't check\n\n- Judgement call on scope. The listing covers the web_search, bing_grounding and bing_custom_search_preview tools as one product, since the web search page says all three use Grounding with Bing Search. The standalone Bing Search APIs are retired and are not listed.\n- firstReleased is 16 May 2025, the date of the retirement notice that names Grounding with Bing Search as the existing replacement. No earlier first-hand launch date was found.\n- unchecked: whether Grounding with Bing Search and the web_search tool are generally available. Only Custom Search is labelled preview on the pages read.\n- unchecked: an SLA for Grounding with Bing. It is a First Party Consumption Service under separate terms, and the Online Services SLA document wasn't opened.\n- unchecked: a public OpenAPI description of the bing_grounding and web_search tool types in the Azure REST API specifications.\n- unchecked: how the general web_search tool is billed when no Grounding with Bing resource is attached. The page says Grounding with Bing incurs costs and links the same pricing page.\n- The terms forbid using Bing output on sites that block the customer's crawler and using its links for crawling or scraping, recorded as facts about the service.\n\n### Sources\n\n- web search tool docs: \u003chttps://learn.microsoft.com/en-us/azure/foundry/agents/how-to/tools/web-search\u003e (seen 2026-11-06)\n- Grounding with Bing tools docs: \u003chttps://learn.microsoft.com/en-us/azure/foundry/agents/how-to/tools/bing-tools\u003e (seen 2026-11-06)\n- Grounding with Bing pricing: \u003chttps://www.microsoft.com/en-us/bing/apis/grounding-pricing\u003e (seen 2026-11-06)\n- Grounding with Bing terms of use: \u003chttps://www.microsoft.com/en-us/bing/apis/grounding-legal-enterprise\u003e (seen 2026-11-06)\n- Bing Search APIs retirement notice: \u003chttps://learn.microsoft.com/en-us/lifecycle/announcements/bing-search-api-retirement\u003e (seen 2026-11-06)\n- Azure status history: \u003chttps://azure.status.microsoft/en-us/status/history/\u003e (seen 2026-11-06)\n- Foundry Agent Service limits and regions: \u003chttps://learn.microsoft.com/en-us/azure/foundry/agents/concepts/limits-quotas-regions\u003e (seen 2026-11-06)\n- Foundry tool catalogue: \u003chttps://learn.microsoft.com/en-us/azure/foundry/agents/concepts/tool-catalog\u003e (seen 2026-11-06)\n- tool best practices: \u003chttps://learn.microsoft.com/en-us/azure/foundry/agents/concepts/tool-best-practice\u003e (seen 2026-11-06)\n- What's new in Microsoft Foundry: \u003chttps://learn.microsoft.com/en-us/azure/foundry/whats-new-foundry\u003e (seen 2026-11-06)\n- azure-ai-projects on PyPI: \u003chttps://pypi.org/project/azure-ai-projects/\u003e (seen 2026-11-06)\n- Microsoft security.txt: \u003chttps://www.microsoft.com/.well-known/security.txt\u003e (seen 2026-11-06)\n\n## Score history\n\nEvery move of a score since the listing was graded, newest first, with its cause.

Use the citations in the response annotations as the sources; the tool output itself is not returned, and the terms require showing the URLs and the Bing query link\n2. Expect each run to bill one transaction per tool call at $14 per 1,000, plus model tokens, and set count and freshness in the tool configuration\n3. Treat cited page text as untrusted input and don't put secrets or personal data in prompts, since queries leave the Azure compliance boundary\n4. On 429 back off exponentially; no Retry-After header is documented for the tool\n\n## Connect\n\nInstall:\n\n```bash\npip install azure-ai-projects azure-identity\n```\n\nFirst request:\n\n```bash\ncurl -X POST \"$FOUNDRY_PROJECT_ENDPOINT/openai/v1/responses\" \\\n -H \"Authorization: Bearer $AGENT_TOKEN\" \\\n -H \"Content-Type: application/json\" \\\n -d '{\"model\":\"'$FOUNDRY_MODEL_DEPLOYMENT_NAME'\",\"input\":\"How does Wikipedia explain Euler identity?\",\"tool_choice\":\"required\",\"tools\":[{\"type\":\"bing_grounding\",\"bing_grounding\":{\"search_configurations\":[{\"project_connection_id\":\"'$BING_PROJECT_CONNECTION_ID'\",\"count\":7,\"market\":\"en-US\",\"set_lang\":\"en\",\"freshness\":\"week\"}]}}]}'\n```\n\nThrough letme: https://letme.dev/bing-grounding. letme answers with the pick and how to call it direct.
