Comparison
Sinyx is built for source-aware AI agent context.
The web extraction space is crowded. Sinyx wins by staying focused: one lightweight API for turning public URLs into Markdown, semantic chunks, citation metadata, freshness, and quality signals that an agent can use immediately.
Where Sinyx Fits
| Question | Why it matters | Sinyx answer |
|---|---|---|
| Do I get more than Markdown? | Agents need content plus source signals, not only converted page text. | context returns Markdown, chunks, citation, freshness, and quality together. |
| Can my agent cite the source? | Source attribution is important for research, documentation ingestion, and audit trails. | Sinyx returns title, author when available, source domain, canonical URL, fetched time, APA, and MLA. |
| Can I store it in RAG? | Raw pages are awkward for vector storage and retrieval. | Sinyx includes semantic chunks with heading paths, character counts, and priority scores. |
| Can I judge whether the page is useful? | Agents should avoid treating every extracted page as equally valuable. | Sinyx returns freshness and quality signals including page type, word count, tables, code blocks, and link density. |
The Sinyx Wedge
The differentiator is format: "context". It returns the content and the source signals together:
{
"url": "https://example.com",
"format": "context"
}
| Field | Why an agent needs it |
|---|---|
markdown |
Readable source content for prompts, summaries, and tool output. |
chunks |
Semantic blocks with heading paths and priority scores for retrieval and memory. |
citation |
Title, author when available, canonical URL, fetched time, APA, and MLA strings. |
freshness |
Fetched time, published/modified dates when available, age in days, and recent signal. |
quality |
0-1 score with page type, word count, code/table detection, and link-density signal. |
Live Context Benchmark
These results were produced through the same RapidAPI path customers use, with format: "context". The benchmark intentionally uses stable public URLs so builders can reproduce the shape of the response.
| URL | Result | Context Signals | Latency |
|---|---|---|---|
| example.com | 200 OK, 149 Markdown chars, 1 chunk | citation domain example.com, quality 0.30, page type webpage |
2.6s |
| IANA example domains | 200 OK, 877 Markdown chars, 2 chunks | citation domain iana.org, quality 0.55, page type webpage |
1.7s |
| MDN HTTP GET | 200 OK, 3,475 Markdown chars, 5 chunks | citation domain developer.mozilla.org, quality 0.73, page type docs |
3.7s |
| Node.js introduction | 200 OK, 3,862 Markdown chars, 2 chunks | citation domain nodejs.org, quality 0.66, page type docs |
2.0s |
| Wikipedia Markdown | 200 OK, 30,000 Markdown chars, 3 chunks | citation domain en.wikipedia.org, quality 1.00, page type docs |

Why Builders Pick Sinyx
- One response shape for agent context instead of stitching together separate extraction, chunking, citation, and scoring steps.
- RapidAPI billing and keys, so teams can test without setting up a separate Sinyx account.
- MCP package for Codex, Claude Code, Cursor, Windsurf, and other agent tools.
- Security controls for SSRF, private networks, protocols, content types, response size, redirects, and timeouts.
