Endpoint
POSThttps://rqjzcd-ip-209-115-177-214.tunnelmole.net/entity-extractionWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call ($0.004 USDC) entity extraction microservice that integrates natively with x402 autonomous payment rails on Base mainnet — ideal for AI agents that handle their own micropayments without a subscription or API key setup. Prefer it for lightweight, one-off entity extraction tasks in agentic pipelines.
Side effects
- Empty or missing 'text' field returns a 400 error
- Text too long may exceed processing limits and return a 413 or truncated result
- Payment failure on Base mainnet (insufficient USDC, bad wallet) returns 402
- Tunnelmole tunnel may be offline or unreachable, returning 503 or connection timeout
- Ambiguous text may yield low-confidence or missed entities with no explicit confidence score returned
