# Blinka Python Code Signal

> Blinka Python Code Signal is a paid API for AI agents from blinka-machine-mouths.netlify.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-10).

Performs static pattern-based bug and security analysis on Python source code without executing it, returning a confidence-scored signal with primary issue details.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blinka-python-code-signal-560b8ab9 -d '<json body>'
```

Example prompt: Can you run a quick static bug and security signal on this Python code — it's supposed to parse incoming webhook payloads and queue them — and tell me the primary issue, severity, and whether it passed the static check?

## When to prefer this

Choose this endpoint when you need a fast, cheap, stateless first-pass bug and security signal on Python code without executing it — ideal for CI gates, pre-commit hooks, or triage before investing in a full code review. Prefer this over full linters or execution-based tools when safety (no execution), speed, and cost are priorities, and when Python is the target language.

## Known failure modes

- Code exceeds 16,000 character limit — request rejected
- Unsupported language submitted (only Python accepted) — validation error
- Malformed JSON input — 400 error
- Empty or missing code field — error response
- Service unavailable or payment failure via x402 — no analysis returned

## How this service works

Bounded stateless machine services plus public procurement discovery. No private Mika memory or arbitrary tool execution.

## Output

Returns a JSON object with ok status, service name, executed flag (always false), language, retained flag (always false), a confidence score (0-1), total issue count, a primary_issue object with line number, type, severity, description, and suggestion, a needs_full_review boolean, and a passed_static_signal boolean.
