All projects on Base matching “code”

Decode what an EVM payment authorization actually authorizes before signing.

Guess the character set of a base64-encoded byte buffer: sniffs a byte-order mark, then falls back to ASCII / UTF-8 validation and a UTF-16 NUL-pattern heuristic. Returns a best-effort charset with a confidence label — a low-confidence guess is still a successful 200.

Fetch any public URL and return its content as base64 with the content type and a ready-to-use data URI. Embed images, PDFs and files directly in LLM and API calls without downloading them yourself. Clean JSON.

Decode any x402/HTTP error into structured recovery instructions. POST /decode-error {"status": 402} or {"status": "timeout"}. Returns meaning, action, retries, backoff, and fix.

Package security scanner — CVEs, license check, typosquat detection.

Decode a MessagePack or CBOR byte stream (supplied as a base64/base64url/hex string) back into a JSON value. A malformed envelope, malformed bytes, or a value that is not JSON-representable is rejected before payment.

Returns a Markdown launch kit and seven-day checklist for an x402 service.
