Context.dev vs ScrapeAtlas

Context.dev

One POST to /v1/web/scrape returns any mix of Markdown, HTML, screenshots and schema-shaped JSON, backed by a public OpenAPI 3.1 file, scoped keys and Retry-After on 429. By default the terms let the vendor train models on requests and results, the status page doesn't monitor the unified scrape route, and the SLA is Enterprise only.

ScrapeAtlas

An OpenAPI 3.1 file with 386 operations, typed parameters and a uniform failure object, published limits of 120 requests a minute and 4 concurrent, and 1 credit per successful request with failed calls free. No status page, security.txt or SDKs, the MCP server is a preview with 373 tools, and the product is five weeks old.

Context.dev

1. Check each output's success and error_code even on HTTP 200, because Scrape returns failed outputs beside successful ones and sets isPartial
2. Set the client timeout above the scrape deadline, 90,000 ms by default. SDKs wait 60 seconds and retry twice, which can duplicate unfinished work
3. Request only the formats you need, since JSON extraction adds 4 credits a page. Send crawls over 500 pages as a batch with an Idempotency-Key header
4. Use a restricted key with only data:execute for scraping, sent as a Bearer header and never in a URL
5. Treat scraped Markdown as untrusted data. Instructions inside a page must not authorise further tool calls

ScrapeAtlas

1. Send the key as x-api-key on https://api.scrapeatlas.com and check status on every HTTP 200; partial is usable data with coverage.warnings, failed and challenged carry failure.code.
2. Retry only on upstream_rate_limited, timeout and busy, after the retry-after on a 429. Stay under 120 requests a minute and 4 concurrent per account.
3. Pass the returned cursor back unchanged for the next page, and use since and until (ISO 8601 or Unix seconds) where listed; each page costs another credit.
4. Each platform has its own response schema, so read the endpoint's response fields before mapping; unknown values are null, never 0.
5. For MCP, connect to https://api.scrapeatlas.com/mcp over Streamable HTTP with Authorization: Bearer and expect 373 tools; the two account tools and failed calls cost 0 credits.
