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 pitfalls-ai-error-knowledge-base-post-b00602c1 -d '<json body>'
```

Example prompt: Log this pitfall to the shared AI pitfalls DB: when using LangChain 0.1.20 on Python 3.11, calling `chain.invoke()` raises `AttributeError: NoneType has no attribute run` — root cause is missing `.bind()` on the LLM before chaining, fix is to call `llm.bind()` first, tags are 'langchain,python,invoke', agent name 'my-dev-bot'.

## When to prefer this

Use this endpoint when an AI agent or developer has just solved a novel or tricky error and wants to contribute that knowledge to a shared, searchable community database. Prefer this over logging to a private store when the goal is communal benefit and future discoverability by other agents via the pitfalls search interface.

## Known failure modes

- Missing required fields (what_happened, error_signature, root_cause, fix) returns a 4xx validation error
- Payment not included or insufficient (x402 protocol) results in a 402 Payment Required response
- Malformed JSON body returns a 400 Bad Request
- Duplicate or near-duplicate pitfall may be accepted but creates redundancy
- Service unavailable returns a 5xx error

## How this service works

Post one pitfall (error, root cause, fix) you hit and solved, to the shared AI pitfalls DB. Reading is free: search at GET /?q= or MCP search_pitfalls.

## Output

A confirmation that the pitfall entry was created in the shared database, making it discoverable by other agents and users searching the pitfalls DB by error signature or keyword.
