PR #173 - firecrawl/cli

What

Bumps the firecrawl SDK dependency from 4.24.0 to 4.26.0 so the bundled axios upgrades from 1.15.2 to 1.18.0.

Fixes #172.

Why

axios@1.15.2 (the exact pin inside firecrawl4.24.0) predates the CONNECT-tunneling fix shipped in axios@1.16.1 (axios/axios#10858, tracked by axios#6320 / axios#6330). Pre-1.16.1 axios sends HTTPS requests through an HTTP proxy in forward-proxy style (POST https://host/path HTTP/1.1) instead of issuing a CONNECT tunnel, so every proxy that only handles CONNECT for HTTPS (xray, squid, tinyproxy, mitmproxy, ...) rejects CLI requests with a non-2xx.

Observed in the wild behind https_proxy=http://127.0.0.1:10808:

$ firecrawl scrape "https://example.com" --json
Error: Request failed with status code 404

Workaround until now: no_proxy=api.firecrawl.dev firecrawl scrape ... (forces the SDK to skip the proxy).

The smallest change that resolves the bug is bumping the firecrawl dep. The axios CONNECT fix first ships in firecrawl@4.25.5 (which bundles axios@1.16.1); 4.26.0 bundles the newer axios@1.18.0 and was chosen to pick up the latest patch in the fix line while keeping the diff minimal. Bumping only to 4.26.0 (rather than straight to 4.31.1) avoids pulling in unrelated changes from later SDK releases.

How I verified

Check	Result
`pnpm type-check`	clean
`pnpm test` (vitest)	390 passed, 1 skipped (no new failures vs baseline)
`axios@1.15.2` through local xray proxy	ERR status=400 (bug reproduced)
`axios@1.18.0` through same proxy	200 OK (CONNECT tunneling works)

Smoke-test capture (ad-hoc script, not included in this PR):

$ node scripts/smoke-proxy.cjs node_modules/.pnpm/axios@1.18.0/node_modules/axios https://example.com
axios version: 1.18.0
OK status=200 bytes=559

$ node scripts/smoke-proxy.cjs node_modules/.pnpm/axios@1.15.2/node_modules/axios https://example.com
axios version: 1.15.2
ERR status=400

Risk

Low. The CLI only consumes public SDK types (Firecrawl, FirecrawlClientOptions, FormatOption, AgentWebhookConfig) and constructor patterns that are stable across 4.24.0 -> 4.26.0. Type-check and full vitest suite pass with no source changes.

Alternatives considered

pnpm.overrides forcing axios to >=1.16.1 while keeping firecrawl at 4.24.0. Works, but forks the dep graph away from what the SDK authors publish; a bump is the upstream-aligned fix.
Bump straight to latest 4.31.1. Also works, but pulls in seven minor versions of unrelated changes. Bumping only to 4.26.0 keeps the diff minimal and the review surface focused on the proxy bug.

AI assistance disclosure

This pull request was prepared with AI assistance. An AI agent (Sisyphus, running on GLM 5.2 via OhMyOpenCode) performed the dependency analysis, ran the verification steps described above, and authored the initial commit and PR description. The fix itself (a one-line dependency bump) was verified manually: the type-check, test suite, and proxy smoke test were all executed and confirmed by the human author before opening this PR. A separate AI-assisted code review (Oracle subagent) was also run on the diff; its findings (a factual correction to the minimum-version claim, now applied) are reflected in this description.

Summary by cubic

Bumped firecrawl to 4.26.0 to pull in axios@1.18.0, fixing HTTPS proxy CONNECT tunneling so the CLI works behind HTTP(S) proxies. Fixes #172.

Bug Fixes
- HTTPS requests now tunnel via CONNECT behind proxies (e.g., squid, mitmproxy).
- The no_proxy=api.firecrawl.dev workaround is no longer needed.
