Agent402 UK Tool Scaffolder
x402
Agent402 UK Tool Scaffolder is a paid API for AI agents from agent402.co.uk, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).
Generates JS or Python pure-function boilerplate code plus an OpenAPI fragment and x402 call pattern from a natural-language description, using deterministic templates with no LLM.

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
Returns a JSON object containing: the generated JS or Python code for the requested pure function, a boolean validity flag, a constraints object confirming pure/no-LLM/no-network properties, and the name of the matched deterministic template used to produce the code.
Example use cases
Luhn validator scaffold for payments
“Generate a pure JavaScript function that validates a credit card number using the Luhn algorithm, and include the OpenAPI fragment and x402 call pattern for it.”
Python codec boilerplate for agent tool
“Scaffold a pure Python function that encodes and decodes Base58 strings — I need the code stub, constraints proof that it has no network calls, and the matched template name.”
ISO IBAN validator tool bootstrap
“Create a pure JavaScript scaffold for an IBAN format validator, with the OpenAPI fragment included, so I can wire it into my agent as a leaf tool.”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/scaffold/toolWhen to prefer
Choose this endpoint when you need a deterministic, reproducible code scaffold for a pure function (validators, codecs, math) and want to guarantee no LLM non-determinism, no network calls, and no side effects in the generated code. Prefer it over LLM-based code generators when auditability, reproducibility, and strict purity constraints matter, or when you need an OpenAPI fragment and x402 payment pattern baked in from the start.
Side effects
- Description does not match any known deterministic template — returns unmatched template or error
- Unsupported language value (not 'js' or 'python') — likely 400 or validation error
- Description is too vague or ambiguous to map to a pure function — may return generic or empty scaffold
- Payment failure via x402 — call not executed if $0.001 USDC charge fails
