/api/v1/ai/comment-analyze

Analyze sentiment, intent category, topics, reply requirements, recommended actions, and priority of a single social media comment.

Base Billing 1 Credit
Typical Response 1-3 s
Client Timeout 15-30 s (recommended)
Provider Fallback Automatic
JSON Contract Envelope v1

Architecture Role & AI Definition

Comment Analyze API provides low-latency, deterministic REST execution for production engineering workflows. It processes structured payloads with strict schema validation, returns uniform JSON envelopes, and is secured via SHA-256 API key authentication with atomic credit pre-authorization locks.

Production Reliability Guidelines

1. Strict Timeout Windows

Configure a hard client timeout of 5 to 8 seconds. If network latency spikes, cancel connection to avoid holding open sockets in worker pools.

2. Exponential Backoff with Jitter

Upon receiving 429 Rate Limit or transient 5xx, pause with exponential backoff:
wait = min(max_backoff, base * 2^attempt + jitter).

3. Atomic Pre-Auth Locks

RSFlowHub acquires an atomic lock verifying base credits before model invocation. If validation fails, zero credits are deducted.

Common Failure Modes & Troubleshooting Matrix

HTTP Code Error Code Root Cause Recommended Remediation
401 API_KEY_MISSING / INVALID_API_KEY No key sent, or the key was mistyped or regenerated. Copy the current key from Dashboard → API Keys and send it as Authorization: Bearer (or X-API-Key).
402 INSUFFICIENT_CREDITS Your balance cannot cover the estimate for this call (base 2 credits plus input/output size). Buy a plan in Dashboard → Billing. Nothing was charged.
422 VALIDATION_ERROR A field is missing, too long or the wrong type, or the body is not valid JSON. Read error.details for the field messages and fix the request. Do not retry the same body.
429 RATE_LIMIT_EXCEEDED Your plan-wide or per-endpoint per-minute limit was reached. Wait the seconds in the Retry-After header, then retry with jitter. Rate limits
502 AI_PROVIDER_ERROR The AI model and its backup both failed. Retry with backoff and check the status page. Nothing was charged.

Technical Q&A (FAQ)

Each Comment Analyze API call costs 2 base credits, plus about 1 credit per 1,000 input characters and 1 credit per 500 output characters. Failed calls are not charged.

The comment field accepts up to 5,000 characters per request. Larger inputs return a 422 validation error, so split long content into chunks.

Comment Analyze API runs on Google Gemini (gemini-2.5-flash), with automatic fallback to OpenAI (gpt-4.1-mini) if the primary provider fails or rate-limits. Models are tuned per task, so your integration does not change when we upgrade them.

Yes. Identical requests within 24 hours are answered from cache, which is faster and free or discounted in credits.

Most requests complete in 1 to 3 seconds; set a client timeout of 60 seconds so a call that switches to a backup model can finish. On HTTP 429, wait for the Retry-After delay. Retry network errors once or twice with exponential backoff and jitter.
