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.\n- Perplexity Search API (82): Read as a closed service with official SDKs and an open-source MCP server. perplexityai 0.46.1 on PyPI on 23 October 2026 and the MCP server's last commit on 21 October, with changelog entries into November 2026 (30). In the 90 days from 8 August, perplexityai 0.43.7 to 0.46.1 (six releases from 2 October), MCP server 1.2.1 (27 August) and 1.3.0 (25 September, Fast Search on perplexity_search), and Fast Search itself in September (20). A changelog with several entries a month, a community forum with a bug-report category, a GitHub discussion repository and api@perplexity.ai. MCP issue reply times weren't read (10 of 15). The MCP server is in the official registry under the domain-verified ai.perplexity namespace, and the Python and TypeScript SDKs are current (15). The MCP repository runs tests in CI and validates its plugin manifests. Its 1.4.0, prepared on 16 October, is not on npm, which still serves 1.3.0, and the registry's latest entry is 1.2.1 of 27 August (7 of 10). 30 + 20 + 10 + 15 + 7 = 82.\n\n### Schema \u0026 documentation: Perplexity Search API +60\n\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- Perplexity Search API (89): OpenAPI 3.1.0 at docs.perplexity.ai/openapi.json describes `POST /search` with typed request and response schemas, listed in llms.txt (25). llms.txt indexes every page, each with a Markdown twin (10). The overview says what a result holds, that snippets can be empty, when to use the Search API instead of the Agent API, and that it takes queries not URLs and does not re-fetch pages (19 of 20). `search_type` is an enum, `max_results`, `max_tokens` and `max_tokens_per_page` carry minimum and maximum, country and language codes carry lengths, and `query` is a string or an array. The recency filter is an enum in the docs, and date filters are `MM/DD/YYYY` strings (14 of 15). Python, TypeScript and cURL examples with a recorded response. The spec documents only 200 and 422 for `/search`, and status codes are listed on the SDK error-handling page and the rate-limit page rather than for Search (11 of 15). A public changelog with several entries a month, dated by month only, and an unversioned `/search` path (10 of 15). 25 + 10 + 19 + 14 + 11 + 10 = 89.\n\n### Security \u0026 auth: Perplexity Search API +41\n\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- Perplexity Search API (56): Project API keys, shown once, revocable, and generated and revoked through two documented endpoints with a rotation guide. No per-key scopes or spending limits were found. The hosted MCP server also takes Sign in with Perplexity (OAuth). Keys go in the Authorization header only (22 of 30, as on the Decisions API listing). Search only reads, and MCP clients can disable tools, but any key reaches every API on the account, including the Agent API's sandbox and MCP tools (8 of 20). Snippets are third-party page text, and no guidance on treating them as untrusted was found in the docs, the MCP server or its SECURITY.md (0 of 15). Responses carry a request `id`, and the console shows usage by key. The Audit API covers enterprise organisations' web app events with its own keys, not API calls (8 of 15). security.txt valid until 31 December 2027 linking a security page, a SOC 2 Type II report, a 2025 HIPAA gap assessment and a CAIQlite listed on the trust centre, and a SECURITY.md on the MCP server that takes private reports through GitHub advisories or security@perplexity.ai. The trust centre is drawn by script and wasn't read (18 of 20). 22 + 8 + 0 + 8 + 18 = 56.\n\n### Reliability: Perplexity Search API +35\n\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- Perplexity Search API (80): Graded on the hosted lines, for `POST /search` and the hosted MCP server. status.perplexity.com, on incident.io since 10 September 2026, has an API component with an RSS feed and a JSON summary. There is no separate Search component (20). In the 90 days from 8 August the feed lists 'Investigating API issue' on 13 August, resolved with no detail, a usage-based billing issue on 3 September, and on 9 October elevated errors on the website, app and Computer, where the API 'remained operational throughout'. Minor only, with the caveat that history before the migration may be incomplete (20). The Search API is limited to 50 query units a second with a burst of 50 on every tier, and the other APIs publish QPS and token limits per tier (15). 429 carries Retry-After and an `error.type`, the SDKs retry 429 and 5xx twice honouring Retry-After, the Search best-practices page shows backoff, and failed or rate-limited searches are not billed. Searches have no side effects (15). The FAQ says Perplexity does not guarantee uptime, failure frequency or recovery time, and the terms carry no SLA (0). No beta label on the Search API, launched on 25 September 2025 (10). 20 + 20 + 15 + 15 + 0 + 10 = 80.\n\n### Agent ergonomics: Perplexity Search API +19\n\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- Perplexity Search API (85): `max_results` 1 to 20, `max_tokens` and `max_tokens_per_page` cap the extracted text, and results are title, url, snippet and two dates. The MCP server has four tools (23 of 25). Domain, language, recency, publication and update date filters and `country`, with up to five queries in one request. No pagination or offset (16 of 20). 429 bodies name the limit hit, the SDKs map status codes to typed errors, and 402 marks an empty balance. Search-specific error bodies beyond 422 validation are not documented (13 of 20). Searches only read, failed and rate-limited requests are not billed, and the MCP server sets readOnlyHint true, destructiveHint false and idempotentHint false on every tool (18 of 20). Only `query` is required. Official Python and TypeScript SDKs, a CLI and a Python Search SDK (15). 23 + 16 + 13 + 18 + 15 = 85.\n\n### Payments \u0026 pricing: Perplexity Search API +5\n\n- 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.\n- Perplexity Search API (25): No x402, MPP or L402 in the docs, pricing page, OpenAPI or llms.txt (0). $5 per 1,000 successful requests, $1 with Fast Search, published without a login, with failed and rate-limited requests not billed (20). Usage is prepaid with a card on the billing page, and no free allowance was found. The console playground needs no key but is a page for a person, not an API allowance (0). A person signs up in the console. The Stripe Projects route provisions a project, key and credits from a terminal, but needs a person's Stripe account with a payment method and a $10 minimum purchase (5 of 20, as on the Decisions API listing). 0 + 20 + 0 + 5 = 25.\n\n## Score by category\n\n| Category | Weight | Mojeek Web Search API | Perplexity Search API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 45 | 80 | Perplexity Search API +35 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 29 | 89 | Perplexity Search API +60 |\n| Agent ergonomics | 13% (16.2 this run) | 66 | 85 | Perplexity Search API +19 |\n| Security \u0026 auth | 14% (17.5 this run) | 15 | 56 | Perplexity Search API +41 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 25 | Perplexity Search API +5 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 10 | 82 | Perplexity Search API +72 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 68 | 66 | Mojeek Web Search API +2 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **36.4 · F** | **70.2 · BB** | |\n\n## Facts side by side\n\n| Fact | Mojeek Web Search API | Perplexity Search API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Mojeek Limited | Perplexity |\n| Hosted endpoint | no (local only) | `https://api.perplexity.ai/mcp` |\n| Transports | | Streamable HTTP, stdio |\n| Auth | API key | OAuth or key |\n| Pricing | Pay per use | Pay per use |\n| Price for web search | $2.68 per 1,000 requests | $1 per 1,000 requests |\n| x402 | no | no |\n| Licence | none | Proprietary service under the Perplexity API Terms of Service.

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**Perplexity Search API.** Raw ranked results with token-capped page text from Perplexity's own index, $5 per 1,000 requests or $1 with Fast Search, an OpenAPI description and a hosted MCP server with read-only annotations. Uptime is not guaranteed, there is no free allowance, keys carry no scopes, and no guidance on untrusted page text was found.\n\n## Before you call either\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### Perplexity Search API\n\n1. Set `max_tokens_per_page` and `max_tokens` before calling; extracted text otherwise fills the context, and the price does not change with size\n2. Skip results with an empty `snippet` and dedupe by `url` when sending a `query` array; each query costs one rate-limit unit\n3. Use `search_type: \"fast\"` for $1 per 1,000 when latency and cost matter more than depth\n4. On 429 wait for Retry-After, then back off; on 402 stop and ask the user to add credits\n5. Use the Search API for sources and the Agent API's web_search tool for a written answer with citations\n\n## Questions\n\n### Which is better for AI agents, Mojeek Web Search API or Perplexity Search API?\n\nPerplexity Search API scores 70.2 (BB) on agent readiness against Mojeek Web Search API's 36.4 (F), and leads in 6 of 7 scored categories.\n\n### Which is cheaper for web search, Mojeek Web Search API or Perplexity Search API?\n\nPerplexity Search API, at $1 per 1,000 requests against $2.68 per 1,000 requests for Mojeek Web Search API.
