  • Free to start without a card

Watch for

No error responses for the tool are documented. The only response example has isError false

Mojeek Web Search API F

Best for Agents and products that want a second, independent index beside Google-derived results, or European data handling with no sub-processors.

Also in its favour

  • Cheaper for web search, $2.68 against $7 per 1,000 requests

Watch for

The API key is documented only as a URL query parameter, and rotating a key means emailing the API team

Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Security & auth Web Search Tool on Amazon Bedrock AgentCore +70

Web Search Tool on Amazon Bedrock AgentCore 85

Gateway inbound auth is OAuth JWT from the owner's identity provider with allowed scopes advertised in the 401 challenge, or IAM SigV4 scoped to one gateway ARN, and the agent never holds a search credential (30). The tool only reads. The owner's target-level include and exclude lists cannot be relaxed by the agent, the service role's InvokeWebSearch names one service-owned ARN, and Cedar policies on the gateway can forbid the tool per caller. A no-authorisation gateway mode exists, with AWS's warning against production use (17 of 20). Results are third-party page text and the Web Search pages give no guidance on treating them as untrusted. Gateway guardrail policies can screen inputs for prompt attacks and suppress outputs, documented in general and not for this tool (7 of 15). CloudWatch metrics by method and tool name, and CloudTrail data events for InvokeGateway when the owner turns them on, at extra cost (13 of 15). A vulnerability disclosure programme on HackerOne, a security.txt that expires on 16 October 2027 (re-read on 1 November), and SOC and ISO 27001 among the programmes the AgentCore FAQ lists. No paid bounty found, so 2 held back as on every AWS listing (18 of 20).

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.

Maintenance & community Web Search Tool on Amazon Bedrock AgentCore +70

Web Search Tool on Amazon Bedrock AgentCore 80

Read for a closed service, from the connector versions page, release notes and What's New, with the control-plane model checked as the other AWS listings are. The newest change is connector 1.3.0 on 19 October 2026, which adds MCP tool annotations, 13 days before 1 November (30). Three dated changes in the 90 days from 3 August, filters and two Regions announced on 19 August, four Regions on 15 October and connector 1.3.0 on 19 October. Connector 1.2.0 (20 July) has left the window, and no bedrock-agentcore-control model commit since then changes the connector shapes (20). Public release notes with RSS, What's New, re:Post and AWS Support. Reply times were not checked (10 of 15). Set-up is in the current AWS SDKs and the AgentCore CLI, which reached 1.0 on 28 October, and the call itself is plain MCP (15). Nothing package-specific to measure for a hosted connector (5 of 10).

Mojeek Web Search API 10

Read for a closed service. No API changelog, release notes or dated API change were found, and the blog's posts since 2024 are about search in general, so the last change can't be dated (0). No dated changes in the 90 days from 8 August (0). A staff member answered API questions on the community forum within a day in December 2025 and October 2026, and support is by email; no public changelog (10 of 15). No official SDKs or MCP server (0). No public packages or CI to measure (0). 0 + 0 + 10 + 0 + 0 = 10.

Schema & documentation Web Search Tool on Amazon Bedrock AgentCore +49

Web Search Tool on Amazon Bedrock AgentCore 78

The tool's inputSchema is published in full as JSON Schema, with query required, and the Gateway control plane is in AWS's service models (25). The developer guide has an llms.txt of 1,024 lines on 1 November and serves every page as Markdown (10). The page explains purpose, use cases, the two filter layers and how they compose, but says nothing on when another tool fits better (12 of 20). Types are given, but the 200-character limit on query, the 1 to 25 range of maxResults and the ISO-8601 date format sit in descriptions, with no maxLength, minimum, maximum or format (9 of 15). Python, AWS CLI and AgentCore CLI set-up examples and one response example. No error responses for the tool are documented, and the June release note links to a page that now redirects to the guide's front page (7 of 15). Semver connector versions with release dates (1.3.0 on 19 October 2026), a lifecycle table, monthly release notes and dated What's New posts (15).

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.

Reliability Web Search Tool on Amazon Bedrock AgentCore +45

Web Search Tool on Amazon Bedrock AgentCore 90

Graded on the hosted lines, for the Gateway endpoint and the connector agents call. AWS Health Dashboard with per-service, per-Region history (20). The dashboard's history file, re-read on 1 November 2026, names AgentCore in one event in the 90 days from 3 August, 2 hours 40 minutes of packet loss in one zone of eu-south-2 on 4 October 2026, marked informational and in a Region where Web Search is not sold. The us-west-2 events of 3 September and 30 October (API Gateway HTTP API) don't name AgentCore. Read as clean, as on the Memory listing (30). Quotas published and re-read on 1 November, 10 Web Search requests a second and 200 tool calls a second per gateway and per account (15). Owner-set gateway rate limits return an error body with retryAfter in seconds and searches have no side effects, but the response to the service's own Web Search quota is not documented (10 of 15). The AgentCore FAQ says the Amazon Bedrock SLA applies, but that SLA, last updated 4 October 2023, does not name AgentCore (5 of 10, as on the Code Interpreter listing). Generally available since 16 June 2026 (10).

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.

Payments & pricing Web Search Tool on Amazon Bedrock AgentCore +10

Web Search Tool on Amazon Bedrock AgentCore 30

No x402, MPP or L402 on the Gateway or the tool. AgentCore payments is a separate component for an agent paying third parties (0). Per-query price published without a login, $7.00 per 1,000, with a worked example that adds Gateway invocations at $0.005 per 1,000 (20). No Web Search allowance, but new AWS accounts get up to $200 in Free Tier credits and the Free Tier FAQ says most new customers need no payment method, so half, as on the other AWS listings (10). A person signs up in a browser and sets up a gateway, a target and IAM (0).

Mojeek Web Search API 20

No x402, MPP or L402 (0). Per-request prices published without login, £2 and £3 per 1,000 requests (20). The FAQ says a free credit comes with the Startup plan, but a bank card is required to open an account (0). A person signs up in a browser and adds a card (0). 0 + 20 + 0 + 0 = 20.

Agent ergonomics Web Search Tool on Amazon Bedrock AgentCore +9

Web Search Tool on Amazon Bedrock AgentCore 75

One tool with a compact schema, and results are snippets AWS says are extracted for model context. Each result comes as a JSON string in a text block and again as structuredContent (22 of 25). maxResults 1 to 25, per-request domain include and exclude lists and published-date bounds from 1.2.0. No pagination, offset, country or language controls (15 of 20). JWT failures return 401 or 403 with a WWW-Authenticate header naming the scopes, and throttling returns retryAfter, but no error codes for the tool itself are documented (10 of 20). Searches only read, so retries are safe apart from the per-query charge. Connector 1.3.0 (19 October 2026, now the default) adds a title and readOnlyHint: true and openWorldHint: true to tools/list, per the connector versions page read on 1 November. No idempotentHint, and older pinned targets don't carry the annotations until updated (16 of 20, up from 12 when annotations were unconfirmed). Only query is required, and since the default moved from 1.1.0 to 1.3.0 a target created without a version gets the filters. A first call still needs a gateway, a target, a service role and inbound auth. Any MCP client calls it, and set-up runs through AWS SDKs in many languages (12 of 15, up from 10).

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.

Verdicts

Web Search Tool on Amazon Bedrock AgentCore

One compact MCP tool returns ranked snippets with URLs, titles and published dates from an Amazon-operated index, with domain and date filters and a read-only annotation on the default connector, at $7 per 1,000 queries. A first call needs an AWS account, a Gateway with inbound auth, a target and a service role, and tool errors are not documented.

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.

Before you call either

Web Search Tool on Amazon Bedrock AgentCore

  1. Call tools/list on the gateway and take the tool's name from it. AWS's call examples name gateway tools by target and tool
  2. Keep query to 200 characters and maxResults between 1 and 25 (default 10). The published schema states these limits only in descriptions
  3. Check the target's connector version before sending filters. Version 1.1.0 exposes only query and maxResults; 1.2.0 and the default 1.3.0 take filters
  4. Keep each result's URL and title with any answer built from it. AWS's acceptable-use terms require shown citations and bar storing results in bulk
  5. On a throttled request, wait the retryAfter seconds in the error body. The default quota is 10 Web Search requests a second, adjustable

Mojeek Web Search API

  1. Send fmt=json, since the default response is XML
  2. Read response.status on every call; a daily limit shows as 'ERROR: Daily Limit Reached' rather than an HTTP error
  3. Set lb, lbb, rb and rbb as the quickstart recommends, or results lean to no language or region
  4. Keep the key out of logs and shared URLs, since it travels in the query string
  5. On the Startup plan, don't keep results for more than an hour
