How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
A JSON object with an 'ok' boolean, a 'meta' summary of valid/invalid counts, and an 'items' array with per-identifier results including: validity boolean, detected format, parsed fields (e.g. countryCode for IBAN, gtin14 for GTIN, checkDigit), and a 'reason' string explaining any validation failure.
Example use cases
Example prompt
“Can you validate these three identifiers for me in one go: IBAN 'DE89 3704 0044 0532 0130 00', ISIN 'US0378331005', and GTIN '0036000291452'? Tell me which ones are valid and why any might be invalid.”
Technical details
Endpoint
POSThttps://2s.io/api/validate/batchWhen to prefer
Use this endpoint when you need to validate multiple financial or trade identifiers in a single API call without setting up an account or paying monthly fees. Ideal for compliance pipelines, data quality checks on financial data ingestion, or verifying user-submitted codes across IBAN, ISIN, CUSIP, GTIN, LEI, BIC, GLN, ABA, and SSCC formats. Pay-per-call pricing via USDC makes it cost-effective for low-volume or sporadic validation needs.
Side effects
- Invalid identifier type string returns error for that item
- Empty items array rejected (minItems: 1)
- More than 100 items rejected (maxItems: 100)
- Malformed JSON body returns 400
- Payment failure via x402 returns 402 Payment Required
- Unsupported identifier type string causes item-level error
