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- Mojeek Web Search API (15): One key per account, documented only as the `api_key` query parameter, and rotation or revocation is by email to the API team (a staff reply of 22 October 2026 on the community forum asks for the key's last 8 digits). One all-powerful key (10) less 10 for the key in the URL (0). Search is read-only and there is nothing to write, but no scoped or restricted key (10 of 20). Results are third-party titles and snippets, with no prompt-injection guidance found (0). No audit log or per-call usage view was found in the docs; the FAQ mentions budget alerts on the account (0 of 15). security.txt names security@mojeek.com, with no Expires field. No bug bounty, disclosure policy, SOC 2 or ISO 27001 found; the API page claims compliance with European rules such as the EU Data Act without a certification (5 of 20). 0 + 10 + 0 + 0 + 5 = 15.\n\n### Schema \u0026 documentation: Grounding with Bing Search +39\n\n- Grounding with Bing Search (68): 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- Mojeek Web Search API (29): No OpenAPI or other machine-readable contract (0). No llms.txt (404) and no Markdown pages for agents (0). The parameters page states what each parameter does, with notes on when not to use `reg` and `clufmt`, but nothing on when another endpoint fits better (12 of 20). Every parameter has a type, defaults and valid ranges (tlen 0 to 127, dlen 0 to 511, rbb and lbb 1 to 100, up to 25 domains), though `reg` is called an enum without listing its values (11 of 15). One curl example and annotated JSON and XML response formats; errors appear only as a `status` string with one example (6 of 15). No API version, changelog or dated release notes, and the quickstart and the parameters page give different hosts (0). 0 + 0 + 12 + 11 + 6 + 0 = 29.\n\n### Reliability: Grounding with Bing Search +23\n\n- Grounding with Bing Search (68): 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- Mojeek Web Search API (45): Read with the hosted lines. status.mojeek.com is a Site24x7 StatusIQ page with Search, Website, Blog and Community components. It is drawn by script, so only its RSS feed could be read, which shows each component's current state (Search operational since 7 September 2026) and no incident entries (15 of 20). No readable incident history (5). Rate limits are published per plan, 5 a second and 100,000 a day on Startup, 10 a second and 400,000 a day on Business (15). Over the daily limit the JSON `status` reads 'ERROR: Daily Limit Reached'; no HTTP 429, Retry-After or backoff guidance was found (0). No SLA, and the API terms say the service is provided as is and may be interrupted without notice (0). Generally available, with only the `lr` parameter marked beta (10). 15 + 5 + 15 + 0 + 0 + 10 = 45.\n\n### Agent ergonomics: Mojeek Web Search API +5\n\n- Grounding with Bing Search (61): 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- Mojeek Web Search API (66): Responses can be sized with `t` (up to 10, 40 or 100 results by plan), `tlen`, `dlen` and opt-in date and size fields (22 of 25). `s` for paging, `since` and `before`, `site`, included and excluded domains, region and language boosting and safe search (20). Errors are a free-text `status` with no documented codes, which an agent can't branch on reliably (5 of 20). Searches only read, so a retry is safe, but no page says whether failed or empty requests are billed (12 of 20). Only `q` and `api_key` are required, with recommended values for the boosts. No official SDK in any language (7 of 15). 22 + 20 + 5 + 12 + 7 = 66.\n\n## Score by category\n\n| Category | Weight | Grounding with Bing Search | Mojeek Web Search API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 68 | 45 | Grounding with Bing Search +23 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 68 | 29 | Grounding with Bing Search +39 |\n| Agent ergonomics | 13% (16.2 this run) | 61 | 66 | Mojeek Web Search API +5 |\n| Security \u0026 auth | 14% (17.5 this run) | 79 | 15 | Grounding with Bing Search +64 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 20 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 80 | 10 | Grounding with Bing Search +70 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 66 | 68 | Mojeek Web Search API +2 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **63.7 · B** | **36.4 · F** | |\n\n## Facts side by side\n\n| Fact | Grounding with Bing Search | Mojeek Web Search API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Microsoft | Mojeek Limited |\n| Hosted endpoint | `https://{account}.services.ai.azure.com/api/projects/{project}/openai/v1/responses` | no (local only) |\n| Transports | Streamable HTTP | |\n| Auth | OAuth | API key |\n| Pricing | Pay per use | Pay per use |\n| Price for web search | $14 per 1,000 requests | $2.68 per 1,000 requests |\n| x402 | no | no |\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 | none |\n| Tools exposed | 3 | 0 |\n| Read-only variant documented | no | no |\n| llms.txt | no | no |\n| Last release | 2026-11-02 | none |\n| Terms last updated | 2025-11-01 | no date given |\n| Privacy policy last updated | 2026-09-01 | 2022-02-02 |\n| Customer content may train models | yes | not found in the text |\n| Terms restrict automated access | yes | not found in the text |\n| Terms restrict benchmarking | not found in the text | not found in the text |\n| Terms or service can change without notice | not found in the text | yes |\n| Arbitration or class-action waiver | not found in the text | not found in the text |\n\n## Verdicts\n\n**Grounding with Bing Search.** First-party Bing grounding inside Foundry Agent Service, called with Entra ID so the agent never holds a search key, at a published $14 per 1,000 transactions. 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**Mojeek Web Search API.** Mojeek sells search over its own independent index at published per-request prices, with region, language, date and domain controls and storage rights on the Business plan. The key travels only in the URL, rotation is by email, a card is needed to start, and there is no OpenAPI, changelog, 429 handling or SLA.\n\n## Before you call either\n\n### Grounding with Bing Search\n\n1. 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### Mojeek Web Search API\n\n1. Send `fmt=json`, since the default response is XML\n2. Read `response.status` on every call; a daily limit shows as 'ERROR: Daily Limit Reached' rather than an HTTP error\n3. Set `lb`, `lbb`, `rb` and `rbb` as the quickstart recommends, or results lean to no language or region\n4. Keep the key out of logs and shared URLs, since it travels in the query string\n5. On the Startup plan, don't keep results for more than an hour\n\n## Questions\n\n### Which is better for AI agents, Grounding with Bing Search or Mojeek Web Search API?\n\nGrounding with Bing Search scores 63.7 (B) on agent readiness against Mojeek Web Search API's 36.4 (F), and leads in 4 of 7 scored categories.
