# CSV Date Profile

> CSV Date Profile is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Profiles ISO date parse success rates for selected columns in a CSV dataset, returning counts, normalized values, and a versioned validation result.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/csv-date-profile
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/csv-date-profile-db0eeae1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_TXBPvWsmlMULq__DVIdIb

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability csv-date-profile-db0eeae1 -d '<json body>'
```

Example prompt: Can you profile the date columns 'order_date' and 'ship_date' in this CSV to see how many rows parse successfully as ISO dates and what the normalized values look like?

## When to prefer this

Use this endpoint when you need a fast, deterministic, in-memory check of ISO date parse quality across specific CSV columns before handing structured data to a downstream tool with a stricter schema contract. Prefer it over general-purpose data validation tools when you specifically need per-column date parse counts and normalized outputs in a versioned JSON format without any data retention.

## Known failure modes

- Malformed CSV text causing parsing errors
- Column names not found in the provided CSV
- Input text exceeding 8192 character limit
- Column array exceeding 256 items limit
- Non-ISO date formats causing low parse success rates returned as findings rather than errors
- Payment failure via x402 resulting in 402 response

## How this service works

CSV Date Profile: CSV Date Profile profiles ISO date parse success for selected CSV columns from bounded caller-supplied values without an external provider. Call CSV Date Profile before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Date Profile as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-…

## Output

Returns a versioned deterministic JSON object containing ISO date parse success and failure counts per column, normalized date values for parseable entries, and a structured validation finding summary — all computed in-memory without data retention.
