# Agent Digest

> Agent Digest is a paid API for AI agents from kassa-402.annushka1190.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Summarizes text into key-sentence bullets, labels sentiment, and extracts entities (emails, URLs, EVM/Solana addresses) in a single pay-per-request call.

## 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 agent-digest-dd2f725f -d '<json body>'
```

Example prompt: Can you digest this text for me — pull out the key bullet points, tell me the sentiment, and extract any emails, URLs, or crypto wallet addresses you find: "We loved the product! Contact us at hello@example.com or visit https://example.com. Send rewards to 0x1234abcd..."

## When to prefer this

Choose this endpoint when you need lightweight, multi-function text processing — summarization, sentiment, and entity extraction — in a single low-cost call without setting up API keys or accounts. It is ideal for AI agents that process arbitrary user-supplied text and need to extract structured signals (crypto addresses, emails, URLs) alongside a digest, especially in Web3 or crypto contexts where EVM/Solana address extraction is a first-class feature. Prefer alternatives if you need deep NLP pipelines, custom entity types, or bulk batch processing.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text below minLength of 1 character rejected
- Payment not completed via x402 results in 402 Payment Required response
- Extremely long text may be truncated or timeout
- No entities of a given type found returns empty array for that category
- Malformed payment header causes authentication failure

## How this service works

Lightweight text utilities for AI agents: key-sentence digest, sentiment label, and entity extraction (email, URL, EVM/Solana addresses). Pay-per-request in USDC on Base and Solana via x402. No API keys, no accounts, no signup.

## Output

Returns a JSON object with a 'count' of key sentences and a 'bullets' array of those sentences, plus a sentiment label (positive/negative/neutral) and a list of extracted entities including emails, URLs, EVM wallet addresses, and Solana wallet addresses found in the input text.
