How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing extracted token identifiers found within the input text, structured for downstream consumption by agents or pipelines. The exact fields are flexible (additionalProperties: true) but will reflect the identifiers detected in the provided text.
Example use cases
Extract IDs from invoice text
“Pull all the identifiers out of this invoice text so I can store them: 'Invoice #INV-2024-0042 references order ORD-9981, customer CUST-00123, and payment token PT-XYZ987.'”
Parse token references in agent logs
“Go through this agent log output and extract every token identifier you find — I need a structured list of them for downstream processing.”
Identify tokens in contract document
“Read this contract excerpt and give me all the identifier tokens in it — things like reference numbers, IDs, and codes: 'Contract REF-2024-CONTRACT-001 between entity ENT-A and ENT-B, tracking code TRK-55902.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/identifiers/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract or enumerate token identifiers from free-form text as a lightweight, pay-per-call utility. It is ideal for autonomous agent pipelines that process documents, logs, or unstructured data and need to surface structured identifiers cheaply ($0.0007 USDC per call). Prefer it over heavier NLP services when the task is specifically identifier/token extraction rather than general entity recognition or sentiment analysis.
Side effects
- Text exceeds 50000 character limit — request rejected or truncated
- Empty or missing 'text' field — validation error returned
- Payment failure via x402 — 402 response, call not processed
- Ambiguous or identifier-poor text — empty or minimal result set returned
- Service unavailability on Cloudflare Workers edge — 5xx error
