Search issues, merged pull requests, READMEs, and documentation. Use when the question is how a library or API behaves, what an error means, or whether a bug was fixed; prefer this over a general web page.

firecrawl developer

Answer a developer question from the primary source: the issue, the merged pull request that fixed it, or the README/docs passage that states the contract.

Quick start

bash

mkdir -p .firecrawl
firecrawl developer "how do I configure retries" --limit 10 -o .firecrawl/developer.json --json
jq -r '.results[] | .id, .url, .passages[].text' .firecrawl/developer.json

Run

firecrawl developer --help

for the full option list.

HTTP:

GET|POST https://api.firecrawl.dev/v2/search/developer

. MCP:

firecrawl_developer_search

. Each hit carries

id

,

url

,

passages

. Kind is the

id

prefix (

doc:

,

issue:

,

pull_request:

,

readme:

). Hits do not carry a

type

field.

Done when: the answer quotes a matched passage and cites its

url

(fall back to

url

when

title

is absent), or you have moved to the open web because the index had nothing to say.

Tips

Default first move is
```
firecrawl developer
```
. Use
```
search --categories developer
```
only when you are already running a web search and want developer hits in the same call (no passage control, no index filters).
Literal error or stack trace: search the string plus the library name. On HTTP,
```
types=["issue","pull_request"]
```
. Strip paths, line numbers, and ids, then retry.
API contract:
```
readme
```
and
```
doc
```
are authoritative. A merged PR supersedes an issue report. Never answer from an opening report alone.
Scope last: search the whole index, then narrow with HTTP
```
types
```
,
```
repos
```
, or
```
sources
```
. If a scoped search is empty, read the echoed
```
indexed
```
flag before concluding the repo is missing.
Repository filters (
```
language
```
,
```
topic
```
,
```
license
```
,
```
min_stars
```
, …) drop
```
doc
```
results unless you also pass
```
sources
```
.
```
types
```
,
```
repos
```
,
```
sources
```
,
```
passages
```
, and those repository filters are HTTP-only.
Comparison, opinion, news, or an unindexed project:
```
firecrawl search
```
, then
```
firecrawl scrape
```
.
