How this service works
Call when an agent needs LEI-shaped tokens extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/regex-lei first.
Output
A list of up to 20 LEI-shaped token strings found in the input text, extracted via regex pattern matching. If no LEIs are found, an empty list is returned — but the call is still billed at $0.009 USDC.
Example use cases
LEI extraction from regulatory filings
“I have a block of text from a MIFID II trade report — can you pull out all the Legal Entity Identifier codes mentioned in it? The text is: 'The reporting entity 2138003EK6OUNFMVD668 transacted with 549300MLUDYVRQOOXS22 on 2024-01-15.'”
Compliance document LEI audit
“Go through this compliance document excerpt and list every LEI token you find: 'Firm A (LEI: 254900OPPU84GM83AG42) and Firm B (LEI: 335800CL3OEUVJNWC510) are both registered counterparties.'”
Financial contract counterparty identification
“Here's a section of a derivatives contract — can you identify all the LEI-shaped identifiers in it so I know which legal entities are involved? Text: 'The swap is between 969500CHL179GLOQ5834 acting as dealer and 222100ZUV97Z84LBSH51 as client.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-lei?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, deterministic, offline regex-based extraction of LEI-format tokens from text, with no LLM or network dependency. Prefer the free sandbox endpoint POST /v1/sandbox/regex-lei first for testing. Choose this over LLM-based entity extraction when you need exact 20-character alphanumeric LEI pattern matching at low cost and high reliability.
Side effects
- Empty match list returned (and billed) when no LEI-pattern strings exist in the input
- Input text exceeds 100,000 character limit — request rejected
- Input text is empty or missing — request rejected
- More than 20 matches exist in text — only the first 20 are returned, remainder silently truncated
- Payment of $0.009 USDC not provided — request rejected via x402
