Agent402 UK Batch Utility Processor
x402
Agent402 UK Batch Utility Processor is a paid API for AI agents from agent402.co.uk, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Execute up to 50 deterministic utility operations in a single paid batch: hashing, base64, JSON formatting/diffing, text metrics, markdown-to-HTML, slugification, and UUID generation.

How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
A JSON object with a 'results' array (one entry per operation, each with ok: true/false, the op name, and the result payload) plus a summary object showing total, succeeded, and failed counts. On partial failure (when stop_on_error is false), completed operations still return their results.
Example use cases
Content pipeline slug and hash generation
“I need to process these 10 blog post titles: slugify each one and also SHA-256 hash each slug so I can use them as cache keys — do it all in one batch call.”
Multi-format JSON audit mid-task
“I have three JSON payloads from different APIs — can you format all three and diff the first against the second in a single batch, stopping on the first error?”
Markdown to HTML for multiple articles
“Convert these 8 markdown snippets to HTML and get word counts for each one in the same request — I need both outputs together before I publish.”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/utils/batchWhen to prefer
Use this endpoint when an agent needs 5 or more deterministic utility transformations mid-task and wants to avoid multiple round-trips and multiple payments. It is strictly better than calling individual utility endpoints when n≥5 because the $0.01 flat fee covers the entire batch. Prefer it over language-model-based transformation when exact, reproducible outputs are required (e.g., canonical hashes, RFC-compliant UUIDs, lossless base64).
Side effects
- Array exceeds 50 items — batch rejected
- Unrecognized op type — item marked failed with error detail
- Malformed JSON input for json-format or json-diff — item fails
- stop_on_error: true halts processing and returns only results up to the failed item
- Payment not received or x402 handshake fails — 402 response, no processing
- Missing required fields for a specific op — that item returns ok: false
