API Reference

Blast commands, REST endpoints, Python SDK, and 21 MCP tools. Everything you need to integrate.

Blast Commands

The fastest way to use c4reqber from the command line. All commands support --help for detailed options.

$ blast solve "your research question"
$ blast turbo "complex multi-step problem"
$ blast flash "quick check"

Command	Description	Latency
`blast solve`	Standard discovery pipeline — full Z₃³ traversal	~5s
`blast turbo`	Accelerated path — skips low-relevance states	~2s
`blast flash`	Instant answer — single best engine	<1s
`blast turbofactory`	Batch processing from file	~1s/query

REST API Endpoints (v5.6.0)

Base URL: /api/v1

GET /health Service health check

POST /solve Submit a problem for discovery

GET /solve/{job_id} Get discovery results

POST /agenda Create a research agenda

GET /agenda/{agenda_id} Get agenda status and results

POST /verify Verify a hypothesis against knowledge sources

GET /engines List available simulation engines

GET /sources List configured knowledge sources

Example: Solve a Problem

curl -X POST https://api.c4reqber.org/v1/solve \\
  -H "Authorization: Bearer $TOKEN" \\
  -H "Content-Type: application/json" \\
  -d '{
    "query": "Find novel approaches to protein folding",
    "engines": ["biology", "optimization"],
    "max_depth": 3
  }'

Example: Create Agenda

curl -X POST https://api.c4reqber.org/v1/agenda \\
  -H "Authorization: Bearer $TOKEN" \\
  -d '{
    "topic": "Quantum computing applications in drug discovery",
    "duration_days": 30,
    "milestones": 5
  }'

Python SDK

from c4reqber import Client

client = Client(api_key="your-key")

# Solve a problem
result = client.solve("Novel battery chemistry")
print(result.discoveries)

# Create a research agenda
agenda = client.create_agenda(
    topic="Climate adaptation strategies",
    duration_days=90
)

# Verify a hypothesis
verification = client.verify(
    hypothesis="Solar geoengineering reduces crop yields",
    sources=["pubmed", "nature", "arxiv"]
)
