• get_key

  Get a FlexYield API key with no signup: public supply, 10,000 weighted units per UTC day, 5 requests/s, every tool. Use it once, when you have no key yet; then send the key as the bearer on every other call. Not for a key you already hold (use what_can_i_do to see where it stands

• bind_key_start

  Step 1 of binding the API key you are calling with to a wallet: returns the exact SIWE (EIP-4361) message that wallet must sign. Use it when your key came from get_key and you want it to persist across sessions with 1M units/month. Not for claiming an agent you already run on ano

• bind_key_complete

  Step 2 of binding the API key you are calling with to a wallet: pass the wallet's signature over the message from bind_key_start. Use it right after bind_key_start, with the same key. Not for the first step (use bind_key_start) and not for agent claims (use claim_agent_complete).

• claim_agent_start

  Step 1 of claiming an agent by its EVM address for the account you are calling with: returns the exact SIWE message the agent's wallet must sign. Use it when an account owner wants a budgeted key for an agent that proves control of a wallet. Not for binding your own key (use bind

• claim_agent_complete

  Step 2 of claiming an agent: verify the wallet's signature over the message from claim_agent_start and equip the agent with its own budgeted API key (default 50000 requests/month). Use it right after claim_agent_start. Not for the first step and not for changing a budget later (u

• create_api_key

  Create an additional API key on the account you are calling with (a name, optional monthly unit cap). Use it to give a service or a teammate its own key with its own budget. Not for your first key (use get_key, no signup) and not for a wallet-proven agent key (use claim_agent_sta

• configure_key

  Configure one API key of your account by id: monthly_request_cap (a monthly unit budget; omitted = unchanged, 0 = remove the cap), enabled (the list of services it may use: rpc, data, gas, tx_status, ens, prices, contracts, utils) and caps ({service_key: units} per service). Use

• revoke_api_key

  Revoke one API key of your account by id; calls with that key stop working immediately and the key cannot be restored. Use it when a key leaked or a service is retired; ids come from list_api_keys. Not for pausing a key (set its budget to a small cap with configure_key instead) a

• list_api_keys

  List the API keys of your account (scope='keys', default) or its agent fleet with wallet claims and budgets (scope='agents'). Use it to find a key id before configure_key or revoke_api_key, or to see which keys are in use. Not for usage numbers (use get_usage) and not for your ow

• get_billing_status

  Billing state of your account: tier, whether payments are live, the subscription (plan, interval, price in USD cents, status, period end, cancel-at-period-end), the card on file (brand, last4, expiry — never the number), prepaid pack balances, any founding-price reservation and t

• configure_services

  Read or change the account-wide service settings: which gateway services (rpc, data, gas, tx_status, ens, prices, contracts, utils) are enabled and an optional monthly unit cap per service. Use it with no arguments to read; pass enabled and/or caps to change. Not for one key's bu

• update_account

  Update your account's preferences: notifications (notify_incidents, time_zone) and/or the insights that tailor the service (use_case, team_size, volume, region, previous_provider, referral_source, chains, wish_chains, wish_chain_other). Use it when the owner's preferences change;

• join_enterprise_wishlist

  Send FlexYield an enterprise wishlist: what would need to be true for you to run on FlexYield (chains, SLAs, compliance, features, prices; max 1000 chars) plus a contact email; the founders reply by email. Use it when the public plans do not fit and a human wants to talk. Not for

• join_waitlist

  Join the FlexYield early-access waitlist with an email and a qualifier (developer, investor or curious). Use it only when a human asked to be kept informed; an agent that needs access now should call get_key instead. Not for support (use manage_tickets) or enterprise needs (use j

• list_plans

  List FlexYield's public plans: price in integer USD cents, billing interval, monthly included units and burst rate limits, plus the enterprise line and the signup URL. Use it to compare plans or before telling an owner what an upgrade costs. Not for what a single call costs (use

• get_usage

  Your account's usage in one of three views. view='report': requests, weighted units, errors and latency per key, method and chain over a look-back window (hours, default 24; optional chain). view='stats': one console report — report='latency' | 'errors' | 'spend' | 'cache' — for

• get_statement

  Your account's statement for one billing period (default: the current one): invoice facts plus usage grouped by API key or agent, chain and method class — requests, weighted units, cache hits, refusals; period='list' enumerates the periods available. Use it for month-end reconcil

• manage_tickets

  Your support tickets with FlexYield. action='create' (subject, message, optional request_id of the failing call, optional category) opens a ticket with the call's evidence attached; action='list' (optional status); action='get' (reference); action='reply' (reference, message, opt

• manage_feedback

  Product feedback to FlexYield. action='submit' (kind: 'feature' | 'chain' | 'praise' | 'complaint' | 'other', title, optional body, optional chain) files it and we answer on the feedback page; action='list' (optional status) shows what you filed and our replies. Use it for ideas,

• get_balances

  Native balance and ERC-20 token balances of an address on one chain (eth_mainnet, base_mainnet, arbitrum_one, optimism_mainnet, polygon_pos, solana_mainnet; tokens where a data-capable upstream exists). Use it for a portfolio or a pre-flight funds check. Not for transfer history

• get_history

  Recent asset transfers (sent and received, newest first) of an address on one EVM chain with a data-capable upstream. Use it to answer 'what moved in or out of this address lately'. Not for current balances (use get_balances), one transaction's state (use get_tx_status) or Solana

• get_prices

  Prices. kind='gas' (chain): EIP-1559 gas recommendations (slow/standard/fast) computed from our pool on an EVM chain, 1 weighted unit. kind='token' (symbols, comma-separated e.g. 'ETH,USDC'): current token prices in USD. Use it before sending a transaction (gas) or to value a bal

• get_tx_status

  Status of one transaction hash on any supported chain: confirmed, failed, pending or unknown, with confirmations and gas on EVM chains or slot and commitment on Solana. Use it to poll a transaction you sent or were told about. Not for an address's transfers (use get_history) and

• resolve_ens

  ENS resolution on Ethereum mainnet: pass a name ('vitalik.eth') to get its address, or an address (0x…) to get its reverse-record name, read on-chain through our pool. Use it whenever a user gives you a .eth name instead of an address. Not for other name systems and not for balan

• get_abi

  The verified ABI of a contract (with its name and match level) from Sourcify's open dataset on eth_mainnet, base_mainnet, arbitrum_one, optimism_mainnet or polygon_pos. Use it before calling or decoding a contract you do not have the ABI for. Not for decoding a specific calldata

• decode_calldata

  Decode a transaction's calldata against the target contract's verified ABI (Sourcify): the function signature, its selector and the argument values (static types decoded; dynamic types shown raw and labelled). Use it to explain what a pending or past transaction does. Not for the

• convert_evm

  Offline EVM utilities, no chain call: op='checksum' (EIP-55 checksum and validity of input=address), op='convert' (unit conversion wei…gwei…eth: input=value, from=unit, to=unit), op='selector' (4-byte selector and topic0 of input=function signature) and op='keccak' (keccak256 of

• verify_signature

  Verify a signature offline: mode='personal' checks an EIP-191 personal_sign signature (message, 65-byte 0x signature, optional expected address); mode='siwe' checks a SIWE / EIP-4361 message (the exact signed text plus signature — parses the fields, checks signature and expiry; d

• what_can_i_do

  The status overview of the API key you are calling with: its door (how it was obtained: public via get_key, wallet-bound, or adopted by a paying owner), its tier, the budgets left (month, day, prepaid packs), the fences (its limits) each with a doorway (the path past that limit:

• get_quote

  Quote one JSON-RPC call before making it: the weighted units it costs (standard 1, heavy 2, or not offered) and the USD per 1M units on every lane (a lane = a price tier: cheap, balanced, fast). Use it when an owner asks what a workload would cost or before a heavy method. Not fo

• explain_error

  Explain a FlexYield error code (e.g. -32007): what it means, the steps to take and its doorway (the path past the limit that caused it). Use it whenever a call returned an error with a code you do not know, before retrying or filing a ticket. Not for upstream chain errors that ar

• recommend

  A recommendation from our live measurements. what='chain': which chain fits a task (optional family, candidates, prefer), ranked from our probes and method rules. what='route': which lane (price tier: cheap, balanced, fast) to use for one call (chain, method, optional need). Use

• migrate

  A compatibility report for switching your RPC provider to FlexYield: paste your current config as text (endpoint URLs, env lines, code) and get every endpoint mapped to our chain URL, every JSON-RPC method you name with its unit weight and limits, and the list of what changes (au

• buy_pack

  Start the purchase of a prepaid unit pack (size 's': 1.2M units $10, 'm': 7M $50, 'l': 32M $200, +5 % units when bought here) and get a checkout URL the account owner completes on a card; units become available when the payment lands, are consumed after the plan's monthly quota a

• rpc_call
