How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns a JSON object with a single boolean 'result' field indicating whether the query passed the voice synthesis extraction check — true or false with no additional detail or explanation.
Example use cases
Voice pipeline text eligibility check
“I need to know if this sentence is suitable for voice synthesis processing — can you run it through the NLP extractor: 'Welcome to our automated support system, please hold.'”
Batch text pre-screening for TTS
“Before I send these scripts to text-to-speech, check this one through the NLP voice synthesis extractor to see if it qualifies: 'Your appointment has been confirmed for Tuesday at 3pm.'”
Validate narration content
“Can you use the voice synthesis NLP extractor to check whether this narration snippet passes validation: 'In the beginning, the universe was created. This made a lot of people very angry.'”

Endpoint
POSThttps://api.m2mcent.com/nlp-voice-synthesis-extractor-mcp-138/api/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple pass/fail boolean extraction result from an NLP voice synthesis pipeline and are comfortable with the x402 micropayment model on Base L2. Prefer this over full TTS APIs when you only need a validation or eligibility signal rather than actual audio output.
Side effects
- Missing 'query' field returns 400 validation error
- Empty string query may return false or an error
- Payment failure via x402 results in 402 response blocking execution
- Ambiguous or malformed text may return unexpected false negatives
- No detailed error messages returned due to minimal response schema
