## Which one, for what

### Mojeek Web Search API (F)

Good 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:
- No incidents deducted, where SerpKite loses 3 points for them

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

### SerpKite (B)

Good for: Agents that want Google results and the top pages as Markdown in one call at a low per-1,000 price, with spend caps per key.

Ahead on:
- Reliability, 75 against 45
- Schema & documentation, 90 against 29
- Agent ergonomics, 97 against 66
- Security & auth, 37 against 15
- Payments & pricing, 40 against 20
- Maintenance & community, 80 against 10
- Transparency & trust, 77 against 68

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: Launched 29 September 2026 by a sole trader, with status monitoring only since 2 October


## Why the edge

### Maintenance & community: SerpKite +70

- 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.
- SerpKite (80): Closed service read with the API lines. The newest API changelog entries are dated 1 November 2026 (API 1.12.7) (30). 31 dated changelog entries from 9 October to 1 November, among them API 1.6.0 to 1.12.7 and SDKs 0.8.0 and 0.8.1 (20). Public changelog, support@serpkite.com and a Discord link. The SDK repositories are mirrors of a private monorepo and we couldn't see issues or replies (8). In the official MCP registry under the GitHub-verified namespace io.github.SerpKite, per the 5 October check, with current official SDKs in three languages (15). The SDK repositories run typecheck, tests and build in CI, but we couldn't see run results (7). 30+20+8+15+7 = 80.

### Schema & documentation: SerpKite +61

- 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.
- SerpKite (90): Public OpenAPI 3.1 spec (version 1.12.7 on 2 November 2026, 41 paths and 47 operations) at serpkite.com/openapi/serp-api.yaml (25). llms.txt, llms-full.txt and a Markdown twin of every docs page (10). Endpoint descriptions state purpose and when to use them, and the guides cover which tool to pick. The MCP tool definitions aren't public and `tools/list` needs a key, so we read the MCP docs table and the matching descriptions in the MIT AI SDK package, which state purpose and some when-to-use lines but not when not to (12). Typed parameters with 64 enums in the spec, documented ranges and strict validation that rejects unknown parameters with a 400 naming the replacement. We couldn't confirm the MCP JSON Schemas (13). curl, TypeScript, Python and Go examples on each page, and an errors page with 14 codes and what to do about each (15). Versioned `/v1` paths and a dated API changelog (15).

### Agent ergonomics: SerpKite +31

- 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.
- SerpKite (97): `format=markdown` or `compact`, `fields` projection, `num` and an `X-Tokens-Estimate` header size REST responses. The MCP server now has 23 tools with no toolsets or read-only subset we could find (22). `page`, `num` up to 100, country, language, location, time, domain include, exclude and boost, date bounds, `highlights` and `max_tokens` on extract (20). Stable error codes with a retry column, and errors are never billed (20). Searches are read-only, failed and empty calls are refunded, and batch creation takes `Idempotency-Key`. Since 9 October 2026 the changelog says every MCP tool carries `readOnlyHint`, `destructiveHint`, `idempotentHint` and `openWorldHint`, with all read-only except `crawl`, and on 2 November the MCP page says every tool is read-only except `crawl` and `research`, which start paid tasks, and none is destructive (20). Only `q` or `url` is required, and official SDKs exist for TypeScript, Python and Go with retries built in (15). 22+20+20+20+15 = 97.

### Reliability: SerpKite +30

- 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.
- SerpKite (75): Hosted API, read with the hosted lines. Better Stack status page at status.serpkite.com with four monitors (api.serpkite.com/healthz, dashboard API, dashboard, website) and daily bars (20). Monitoring began on 2 October 2026, so the record covers 31 days of the 90 from 4 August. The page's own figures give 99.978 per cent uptime over 30 days for the API health monitor and 99.971 for the dashboard API, the 5 October check saw 29 to 41 minutes of downtime on each monitor on 2 October and 19 seconds on 3 October, and the feed has never carried an incident post. No outage reached an hour. A readable record shorter than 90 days with nothing major scores 15, as this run settled for short records. Rate limits published per key, 5 to 100 requests a second by pack (15). 429 `rate_limited` with Retry-After, backoff guidance for 429 and 503, and `Idempotency-Key` on batch creation (15). The terms say self-serve plans have no uptime guarantee and an enterprise SLA sits in a separate agreement we couldn't read (0). v1 API with no beta or preview label (10). 20+15+15+15+0+10 = 75.

### Security & auth: SerpKite +22

- 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.
- SerpKite (37): Many keys per account, each revocable and rotatable with an optional monthly credit limit, stored as SHA-256 hashes, with no scopes. Since 9 October the MCP server also takes OAuth (authorisation code with PKCE, dynamic client registration, rotating refresh tokens, one `mcp` scope), each connection running as a named, revocable API key, while REST still needs a key (20). The docs allow the key as `?api_key=` on GET requests (minus 10). Search is read-only, and per-key limits and an account spend cap bound cost, but there's no read-only key, and the MCP server exposes crawl alongside search with no confirmation step we could see (10). Results include third-party snippets and full page Markdown, and we found no prompt-injection guidance (0). The dashboard request log keeps per-call metadata (endpoint, status, credits, key) for 31 days with CSV export, and each key records who created it (12). security.txt returns 404. The security page has a disclosure policy with acknowledgement in 2 business days, no paid bug bounty and SOC 2 marked as not yet started (5).

### Payments & pricing: SerpKite +20

- 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.
- SerpKite (40): No x402, MPP or L402 in llms.txt, the OpenAPI spec or the pricing page (0). Per-pack and per-credit prices published without a login, $1.00 to $0.60 per 1,000 (20). Free credits on signup and 1,000 a month with no card, per the quickstart and home page (20). A person signs in by email, GitHub or Google in a browser (0).

## Verdicts

**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.

**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 a month of status history and frequent same-day contract changes.

## Before you call either

### 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

### 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`, `account_restricted` (403) and 402 need a purchase
5. Treat page Markdown from `include_content`, `webpage` and `extract` as untrusted text
