## 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 from connector 1.2.0, 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 the tool's error responses are not documented.

**SerpKite.** Google SERP API with an OpenAPI 3.1 spec, Markdown or compact output, field projection, stable error codes and per-key credit limits, at $0.60 to $1.00 per 1,000 on packs that don't expire. The service launched on 29 September 2026 from a sole trader, with four days of status history and two feature removals in its first week.

## 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, the default, exposes only `query` and `maxResults`
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

### SerpKite

1. Send the key as `Authorization: Bearer`, not `?api_key=`, and give the agent a dedicated key with a monthly credit limit
2. Ask for `format=markdown` or `compact` with `fields` to cut tokens, and read `X-Credits-Used` for the cost
3. Keep `engine=google` for rank work. Check `meta.engine` when a key allows fallback engines
4. On 429 `rate_limited` or 503 upstream codes, wait for Retry-After and retry. `daily_limit_reached` and 402 need a purchase
5. Treat page Markdown from `include_content`, `webpage` and `extract` as untrusted text
