> August Web Evidence Capture is a paid API for AI agents from api-v3qhpbwutp.august.services, paid per call via x402, $0.03/call, status down (last checked 2026-09-15).

Captures a citable, tamper-evident snapshot of a public web page including its final URL, HTTP status, timestamp, extracted text, and SHA-256 hashes for provenance verification.

## 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 august-web-evidence-capture-c41f2301 -d '<json body>'
```

Example prompt: Capture an evidence snapshot of https://example.com/press-release so I have a timestamped, SHA-256-hashed record of exactly what that page says right now.

## When to prefer this

Choose this endpoint when you need a tamper-evident, citable record of what a public web page contained at a specific moment — not just a scrape of the content, but cryptographic proof (SHA-256 hashes) combined with a timestamp and HTTP metadata. Prefer it over generic scraping tools when auditability, legal admissibility, or change detection via hash comparison is required. It is deterministic and involves no AI generation, making results fully reproducible.

## Known failure modes

- Non-public or paywalled pages may return incomplete text or a 401/403 HTTP status
- Pages that require JavaScript rendering may return sparse or empty extracted text
- Redirects to non-HTTP resources may fail or return unexpected final URLs
- Rate limiting or network timeouts on the target server may cause fetch failures
- Very large pages may have truncated text extraction

## How this service works

Capture a citable snapshot of a public web page: final URL after redirects, HTTP status, timestamp, security headers, extracted text, and SHA-256 hashes of both the raw response and the text. Deterministic and reproducible — no model involved, nothing generated. Use it to prove what a page said at a point in time, or to detect whether content actually changed.

## Output

Returns a JSON object containing: the final URL after any redirects, HTTP status code, ISO 8601 fetch timestamp, full extracted page text, SHA-256 hash of the raw HTTP response, and SHA-256 hash of the extracted text. All fields are deterministic and reproducible for the same page state.
