How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with a 'tier' field (value 3) and a 'result' field containing the tier-dependent analysis output for the submitted text. The exact shape of 'result' varies based on the tier's analytical depth.
Example use cases
Customer feedback deep analysis
“Run a deep tier-3 text analysis on this customer review for me: 'The onboarding was smooth and the support team was helpful, but the billing system is confusing and hard to navigate.'”
Content quality evaluation pipeline
“I need you to analyze this article excerpt at the deepest level available and return the structured result: 'Climate change is accelerating at an unprecedented rate, with Arctic ice coverage reaching historic lows for the third consecutive year.'”
Agent-automated text classification
“For each support ticket summary I send you, run tier-3 text analysis through ONE Engine and return the structured output so I can route tickets automatically.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/text-analysis/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deeper, higher-tier text analysis compared to lower-tier siblings (t1, t2), and you need a low-cost, pay-per-call model without subscription overhead. Ideal for autonomous agents making sporadic or high-volume text analysis calls on Base using USDC microtransactions via x402.
Side effects
- Missing or empty 'text' field returns a validation error
- Insufficient USDC balance or failed x402 payment causes a 402 Payment Required response
- Overly long text strings may be truncated or rejected
- Network timeout from Cloudflare Worker under high load
- Malformed JSON body returns a 400 error
