# BlorpAg — bounded text utilities for AI agents

Bounded text utilities over HTTP, paid per request with x402 (USDC on Base). No API key and no account: the paying wallet is the account. Discovery, catalog and quoting are free; execution costs money.

Base URL: https://x402.valintix.com

## Endpoints (paid)
- POST https://x402.valintix.com/v1/summarize — $0.01/request. Bounded extractive summary of the input text (1..8 sentences). Without a reachable gateway the text never leaves this container.
- POST https://x402.valintix.com/v1/transform — $0.01/request. Deterministic, bounded text transforms (case, whitespace, lines). No model involved, no outbound request.

## Free (no payment)
- GET https://x402.valintix.com/health — liveness and which services accept payment right now.
- GET https://x402.valintix.com/v1/catalog — machine-readable catalog: description, input_schema, output_schema, example and errors per service.
- GET https://x402.valintix.com/openapi.json — OpenAPI 3 document for the endpoints above.
- GET https://x402.valintix.com/discovery/resources — x402 discovery document with accepts per resource.
- GET https://x402.valintix.com/.well-known/x402 — the payment requirements a 402 challenge carries.
- GET https://x402.valintix.com/.well-known/agent-card.json — agent card (EIP-8004).
- GET https://x402.valintix.com/llms.txt — this file.
- GET https://x402.valintix.com/v1/privacy — what is stored (short answer: nothing of yours).

## Bounds
- input: 4000 characters, output: 2000 characters, request body: 16384 bytes.
- summarize returns extractive text unless the local model is configured; transform only applies named deterministic operations — no code execution.

## Payment
x402 v1 exact scheme, USDC on Base at $0.01 per request. Flow: POST -> 402 with an X-Payment-Required header and accepts[] -> sign EIP-712 TransferWithAuthorization -> retry with the X-Payment header -> 200. If execution fails the payment is not settled, so the buyer keeps the USDC.

## Not offered
- execute_code — no arbitrary code execution and no outbound fetching.
- scrape_url — no arbitrary code execution and no outbound fetching.
