How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with: the schema name (e.g. 'delx/util-public-registry-id-shape/v1'), a 'kind_guess' field indicating the most likely registry type (e.g. 'lei', 'isin', 'duns'), and a 'valid_shape' boolean indicating whether the string matches the expected format for that registry type.
Example use cases
Validate LEI before compliance filing
“I need to verify that '549300TRUWO2CD2G5692' has the correct format for a Legal Entity Identifier before I submit it in a regulatory filing — can you check its shape and confirm it looks like a valid LEI?”
Classify unknown corporate ID string
“I found this identifier '081420990' in our vendor database and I'm not sure what registry it belongs to — can you tell me what kind of public registry ID it might be and whether its format looks valid?”
Pre-validate batch of identifiers before lookup
“Before I run expensive lookups, can you check if '7LTWFZYICNSX8D621K86' has the right shape for a known registry type like LEI or ISIN, and whether it's structurally valid?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/public-registry-id-shape?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap format-level check on a registry identifier before committing to an expensive live registry lookup. Ideal for pre-validation pipelines, data cleaning, and compliance workflows where you need to classify and sanity-check identifier strings (LEI, ISIN, DUNS, etc.) at scale. Prefer this over full registry lookup APIs when you only need to know if the format is structurally valid, not whether the entity actually exists.
Side effects
- Empty or missing 'value' field returns an error or invalid result
- Ambiguous strings with no clear registry pattern may return a low-confidence kind_guess or null
- Non-string input types may cause validation errors
- Very short or very long strings may not match any known registry pattern
