Call before moving funds on Solana: decision-grade account snapshot — kind; mint decimals/supply/authority; whole-account balance and recent signatures — keyless solana-public-rpc.

Base64 encode or decode a string — base64 encoder/decoder (body {mode:encode|decode,input}).

Hex encode or decode text — hex string encoder/decoder.

conclavex402.pythonanywhere.com

SHA-256 hash/digest of a text string — also sha512 and sha3-256; returns hex.

URL encode or decode a string (percent-encoding) for query, path or fragment.

Call before pricing or settling a crypto payment: live spot prices for one or more coins by CoinGecko id (USD price, 24h change, market cap) from a keyless multi-source chain that never returns an upstream 429.

Call before trading or pricing a token: normalized live onchain snapshot (price, 24h change, liquidity, 24h volume, top DEX pair) plus a transparent buy-side verdict, for a Solana mint (base58) or a Base/EVM token address (0x...).

Call before adding or upgrading a dependency: package-registry metadata for one package (PyPI or npm): latest version, summary, license, dependency count; PyPI also returns 30-day downloads.

Call before onboarding, screening or paying a counterparty: full-text search of SEC EDGAR filings for an enforcement/regulatory phrase; returns matching filings (company, CIK, form, filed/period, state, SIC, accession + official sec.gov deep-link). Phrase search: quote your term, filter by form/date.

Call before moving funds on Solana: decision-grade account snapshot — kind; mint decimals/supply/authority; whole-account balance and recent signatures — keyless solana-public-rpc.

Decode a JWT — parse header and payload claims without a key (no signature verification).

Generate a random UUID (uuid v4, RFC 9562) — 1..100 per call; format uuid|urn|hex|int.

Validate, pretty-print (0-8 spaces), or minify JSON — json formatter/validator.

Validate an IBAN (international bank account number) — check the country, length and ISO 13616 mod-97 checksum; returns validity, country and check digits.

EVM address format, lowercase form and EIP-55 checksum in checksum mode — check an Ethereum/Base address before sending funds.

Base58 encode or decode bytes/hex (Solana-style base58).

Difference between two ISO-8601 timestamps in days/seconds (date diff).

Call before routing or accepting an x402 payment: multi-rail health (facilitators, settlement, market) across x402 rails (JSON).

World clock and timezone converter — convert timezones (timezone convert) for the current time or any instant (`at`) in IANA zones (`tzs`, e.g. Europe/London,Asia/Tokyo) or a fixed utc_offset (+05:30); returns local time, UTC offset, weekday and DST.

Preflight one x402 seller before paying it: ?origin=<seller-url> gives reachable, accepts and findings; omit it for the ecosystem snapshot (JSON).
