## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 6/10 | Web scraping APIs typically return full HTML/content payloads; no evidence of field selection, structured response compression, or pagination hints in the available data. |
| Programmatic Access | 8/10 | Strong access coverage with REST API, official SDKs in Node.js and Python, an MCP server (@crawlbase/mcp), and Pipedream integration, though no OpenAPI spec or GraphQL option. |
| Autonomous Auth | 8/10 | API key-based authentication enables autonomous agent access without human-in-the-loop, and the homepage mentions agents explicitly, indicating design consideration for programmatic use. |
| Speed & Throughput | 5/10 | Web scraping inherently involves network latency to target sites; no data on rate limits, concurrent request support, or conditional request mechanisms like ETags. |
| Discoverability | 6/10 | Developer documentation exists and agents are mentioned on the homepage, but no OpenAPI spec, llms.txt, or agents.json file to aid agent discovery and integration. |
| Reliability | 6/10 | No evidence of idempotency keys, API versioning strategy, or published status page; SDK presence (v1.0.2, v1.0.0) suggests some stability, but limited transparency. |
| Safety | 5/10 | API key scoping appears available, but no evidence of sandbox/test mode, dry-run capability, or rate-limit safeguards specific to agents; robots.txt blocking suggests compliance considerations. |
| Reactivity | 2/10 | Web scraping is fundamentally a polling-based activity with no indication of webhook, streaming, or SSE support for real-time data delivery. |

## Biggest Friction

Lack of an OpenAPI specification and agent-discovery files (llms.txt, agents.json) means agents cannot auto-discover the API schema, requiring manual integration setup.

## Access Methods

- REST API
- SDKs: Node (crawlbase), Python (crawlbase)

## Auth

Methods: unknown. Human required: Yes. Scoped permissions: No.
